The demand for esthetic orthodontic treatment has increased in the past few years. Clear aligner therapy has become widespread orthodontic therapy as an esthetic substitute to conventional fixed orthodontic appliance.
The effectiveness of clear aligners is still controversial due to limited number of research. The outcome of clear aligners had been studied using different indices such as Peer Assessment Rating (PAR) scores and American Board of Orthodontics objective grading system (OGS) occlusal criteria. While these indices are objective, they are only limited to assessing crown movements only.
Evaluating both crown and root movements and position are important during different orthodontic tooth movements and post treatment, respectively. Therefore, the primary aim of this presentation is to discuss the predictability of clear aligner treatment in achieving planned crown and root movements using Cone Beam Computed Tomography (CBCT) for maxillary transverse movements and incisor antro-posterior movements. In addition, the predictability of other tooth movements will be discussed.

Abstract

In recent years, clear aligner has become more and more popular. However, the clear aligner has its own defects, such as material defect, efficacy defect and mechanic defect. In addition, there are still some risks , which are mainly manifested in the risks of high initial stress, IPR risks, periodontal risks of opening deep bite, retracting anterior teeth and distalizing the molars. These defects and risks lead to more problems in clinic, therefore, the author proposes a programmed solution from the anchorage, overbite, torque controls and attachment design aspects including the design, auditing, and monitoring of using clear aligner.

Abstract

Relatively little attention has been devoted to the smile esthetics of elderly people. Possibly, because orthodontics has been historically entwined with the treatment of children and adolescents. Only about 20 years ago adults started to be consistently treated, and several studies have demonstrated the benefits of orthodontic treatment for these individuals, as well as improvements in their quality of life. This presentation will show the results of a prospective trial which enrolled 42 patients who were 65 or older. The protocol consisted of a 6-month-pre-established treatment time with aligners. Our results showed that patients were highly satisfied with the esthetics of the partial treatments. Most patients found that the 6-month treatment time was acceptable and that the clinical results were very positive. The orthodontic treatment significantly improved patients quality of life and self-esteem. Aligner use was comfortable, however, several specific changes in aligner prescription were necessary to solve the common problems presented by this age group. Orthodontic treatment with aligners should be considered as a valuable contribution for older patients quality of life and self-esteem.

Abstract

Clear aligner therapy is ubiquitous in contemporary orthodontics. However, the predictability of achieving specific tooth movements with clear aligners including space closure, distalization and expansion is not absolute. The adjunctive use of customised appliances, retained with mini-implants positioned in the anterior palate, provides the clinician the opportunity to realize specific treatment objectives with greater precision and accuracy. They can be used concomitantly, or as an intermediary step prior to the fabrication of clear aligners.

Abstract

The purpose of the lecture is to highlight the changes occurring during the intraoral service of aligners which includes an array of compositional, surface, structural and mechanical effects. The lecture has two axes: the establishment of effects reported to involve softening, decrease in roughness in the areas which are coming in contact with composite attachments, thereby substantiating a wear mechanism; changes in color, and structural alterations are also described. Having demonstrated the foregoing effects, a number of potential effects on the clinical aspects of aligner treatment and their biological reactivity are discussed. Evidence from studies reporting effect of aligner on oral flora, the release of compounds such as attrition products, release of BPA and monomers as well as attachment composite ageing will be shown. In addition, the assessment of their biological reactivity with emphasis on the cytotoxicity and xenoestrogenicity will be discussed, as well as the impact on efficiency arising from the alteration of hardness, stiffness and relaxation of materials. The implication of these changes and effects in everyday practice will be postulated and guidelines for the minimizing of relevant unwanted effects will be proposed.

Abstract

The high relapse incidence of anterior open bite malocclusion is frequently due to an anterior tongue rest posture. A maxillary fixed intraoral appliance with spurs is recommended to modify tongue posture. Research with this appliance in a large sample of anterior open bite patients demonstrated long term stability post retention.
You will learn why:
-Long term stability of open bite closure is no better than 80%.
-Myofunctional therapy with oral exercises is ineffective in closing open bites.
-TADs used for anterior open bite closure might not have a stable outcome.
-Fixed intraoral spurs are recommended to establish a normal tongue rest posture (a new engram).
-Spurs modify tongue posture and also interrupt digit sucking habits.
-The anterior open bite closes with spurs, without using brackets or wires.
-Long term stability post retention is achieved when spurs are used.
-Spurs are indicated or contraindicated.
-Early correction of open bite protects roots from resorbing.
-Intraoral spurs do not provoke psychological problems.
You will learn the:
-Risk factors for anterior open bite.
-In office construction of the spur appliance.

TMD, open bite, mini-implants and long-term stability

Abstract

Open bite has been one of interesting fields to me, since I started orthodontic residency in 1983. In my department, I have many open bite cases, especially with TMD, because they are referred from local clinics and other orthodontists. Seoul National University Dental Hospital is the final destination of problem cases in South Korea. I think more than 60 % of my patients are open bite cases.
Anterior open bite is a very challenging malocclusion even for excellent orthodontists. It is very difficult to diagnose differentially and to retain the post-treatment result well, because one case may have several etiologic factors. Since MRI and CT were used to screen the etiologic factors, I have realized once more that 'open bite' is one sign of different diseases caused by thumb sucking, tongue thrusting, low tongue posture, mouth breathing, macroglossia, temporomandibular disease and ankyloses of anterior teeth. It cannot be overemphasized to try to find and to remove the causing factors first. According to the causes the open bite should be treated differentially. In this lecture, the following contents will be presented.
1)Etiologic factors of open bite
2)How to find and resolve the etiologic factors
3)Mechanics to close the open bite efficiently
4)Strategies to obtain the long-term stability

Abstract

Anterior open bite is considered one of the malocclusions of most difficult treatment, especially regarding stability. The literature presents many researches on this subject, but with controversial information. There are disagreements on the definition of open bite, its etiology and types of treatment. Possibly, the lack of consensus on the etiology of the anterior open bite may have led to different types of treatment and can be the explanation for the high level of relapse of this malocclusion. The purpose of this presentation is to review the concepts of
anterior open bite focusing on etiology, treatment methods and their stability and present criteria for the diagnosis and treatment of this malocclusion, based in its etiology, with examples of treated cases, stable for over10 years.

Miniplates resist better high discontinuous forces than miniscrews do. Therefore they can be used for intermaxillary orthopedic traction. Class III elastics can be fixed between Bollard anchors on the buttress of the maxilla and in the canine region of the mandible in young growing patients. By stretching of the circummaxillary sutures, the forward growth of the maxilla can be increased, resulting in an anterior rotation of the zygomatico-maxillary complex. Thank s to the sk eletal anchorage, the amount of protraction of the midface is about double of the amount of protraction obtained with face mask . However, new evidence shows that also the chin can be moved back ward without posterior rotation of the mandible, thank s to modeling processes at the gonial angle. This results in a modification of the shape rather than the size of the lower jaw. Furthermore, modeling at the glenoid fossa repositions the mandible slightly posteriorly. The combination of growth modifications of the maxilla and the mandible may result in an important improvement of facial esthetics, also in cleft patients. Successful and stable orthopedics depend on good control of maxillary and mandibular rotations.

Abstract

Here we report a prospective controlled study evaluating the effect of bone-anchored maxillary protraction therapy (BAMP) on the skeletal and airway changes in cleft children with Class III malocclusion using CBCT-derived 3D surface models. Thirty-five unilateral complete cleft lip and palate patients with maxillary deficiency were included. CBCT scans were obtained from each patient before BAMP, 1.5 years and 3.5 years after. Age-matched untreated groups including both cleft subjects and non-cleft subjects served as controls. Majority of the patients showed improved lip projection towards more convex facial profile. The most significant skeletal changes on 3D surface models were observed at the zygomatic regions and at the maxillary complex in favor of the Class III treatment in cleft patients with maxillary deficiency. In addition, significant volumetric increase of the total airway and nasopharynx volumes were observed to a level comparable to a non-cleft control group with a skeletal Class I or mild Class II relationship. Taking into consideration of the effect of normal growth, BAMP can be recommended as an effective therapy for cleft lip and palate patients with favorable skeletal outcome and without impeding development of the airway.

Abstract

Transverse discrepancy is a common skeletal problem which necessitates radical orthopedic correction. The orthodontic envelope of discrepancy is reportedly narrow in the transverse direction, which is why surgically assisted palatal expansion is recommended particularly in grown-up patients. Recently a number of maxillary expanders have been introduced including bone-borne and tooth-and-bone-borne expanders (MARPE). Nonetheless, the expansion modalities have been controversial, due to the lack of understanding on suture biology. Latest findings on the characteristics of craniofacial sutures reveal clues for some critical points, such as speed of expansion, maximum possible age for success of orthopedic expansion, failure rate and optimal expander design etc., along with demonstration of nonsurgical correction of various skeletal problems including Class III and asymmetry

Orthodontists are afraid of causing external apical root resorption (EARR) in their patients as an unwanted side effect of orthodontic treatment. About half of all orthodontically moved teeth show mild to moderate EARR (< 2.5 mm), but luckily only a small percentage end up with severe apical root resorption, defined as a loss of 4 mm of the original root length or more than a third of the root. On the other hand, on the microscopic level over 90% of all orthodontically moved teeth exhibit EARR.
The etiology of EARR is still not fully understood resulting in much uncertainty about how to prevent EARR and how to manage it when it occurs during orthodontic treatment. Furthermore, little is known about the long-term stability and prognosis of affected teeth, including their mobility, vitality, and periodontal status. Despite these uncertainties, patients need to be treated. The Dutch Association of Orthodontists took the initiative to develop a clinical practice guideline through a rigorous methodological approach to support clinicians in making treatment decisions and informing their patients.

Abstract

We all learned that every time we move a tooth, root resorption occurs. However it is reversible and temporary unless it starts at the root apex. Severe root resorption is fortunately rare but nevertheless is still an important consideration. This presentation will summarize what we currently know from all the different studies that have been done ranging from animal studies to theoretical models to genetic studies but mostly from clinical studies and clinical experience. Eight of the most frequently asked questions will be answered that will provide the clinician with the most up to date knowledge focusing mainly on clinical management of root resorption if found at progress or at the end, and which patients are at greater risk.

Abstract

In a previous study (Dudic et al 2013) we found that during an experimentally induced orthodontic tooth movement the presence of interarch interferences decreased the amount of tooth displacement. In the treatment of Class II cases the shift of the molar occlusion from Class II to Class I is often essential to achieve an optimal treatment result. Our hypothesis was that the functional capacity of the masticatory musculature could be a predictive variable in determining the functional appliance treatment outcomes in Class II/1 malocclusion children. During the last decade, we tested this hypothesis in three different samples treated with Tween blocks, Schwarz activators and Andreasen activators, and we found that children with lower pre-treatment maximal molar bite force showed more mesial movement of mandibular first molars, distal movement of maxillary first molars, and larger change in molar class during treatment. Children with thinner pre-treatment masseter muscles demonstrated more mandibular first molar mesialisation and mandibular incisor proclination (Antonarakis, Kiliaridis, 2015, Antonarakis et al 2012, Kiliaridis et al 2010)
In conclusion, the initial condition of the masticatory muscles may partly determine treatment outcomes. Children with thinner pre-treatment masseter muscles or weaker bite force show greater dentoalveolar changes.

Abstract

Orthodontic forces stimulate cell signaling that leads to tooth movement via osteoclast-mediated resorption of alveolar bone adjacent to the pressure side of tooth roots. Because tooth movement is a biologic process, drugs developed to modulate inflammatory cell signaling pathways and/or bone cell activity can be utilized to control orthodontic tooth movement. This presentation will provide current results demonstrating the impact of locally injected drugs for increasing the speed of tooth movement, enhancing orthodontic anchorage during tooth movement, and inhibiting orthodontic relapse after movement. Results and discussion of potential iatrogenic effects of delivered drugs will be presented. Novel methods for polymer-based drug delivery systems to control movement of specified teeth in the mouth will also be discussed.

Abstract

Orthodontic tooth movement through an alveolar atrophic ridge is a treatment alternative for improving the surrounding bone implant dimensions. Sometimes, such challenging movement is needed to close missing teeth arch spaces and to correct an occlusal discrepancy. This presentation will show some studies that discuss the advantages and side effects of such movement, as , for example, root resorption and bone dehiscence. During the presentation, clinical situations will illustrate this important orthodontic strategy, particularly in interdisciplinary treatments.

Abstract

Over the past decade, advances in technology have paved the way for newer restorations fulfilling both esthetic and functional needs of our patients. Long span restorations, bridges, and plates have stepped aside for modern day bio compatible fixtures with superior quality making our treatment much more conservative bridging the gap between what is esthetically pleasing and functionally stable. One thing that has not changed much is the importance of occlusion as one of the main considerations in the treatment planning for restorative and prosthodontic cases. In this modern day of dentistry, planning for veneers, crowns, bridges and implants requires a TEAM APPROACH in order to achieve the best possible outcome. The orthodontic specialist plays a very important role in the establishment of occlusion placing the teeth in the best possible positions that will allow easier placement of the restorations in a much more ideal manner while maintaining a stable and harmonious bite that will ensure the longevity of not only the restoration itself but the supporting structures as well. This lecture will put emphasis on some treatment planning guidelines for adjunctive orthodontic procedures such as space management, control of midline, strategic movement of molars , planning for implants and veneers and other procedures that will help to establish both an eshtetically pleasing smile, healthy look and stable bite in preparation for other restorative and prosthodontic treatment.

Abstract

Tooth size arch length discrepancy (TSALD) is the main reason for the decision of extraction of dental units from the arches. The space thus created is used for alignment / decrowding or retraction of procumbent anteriors. The most common choice of extraction, for the space gaining in the management of malocclusion, is premolars. In some clinical situations, molars may have to be extracted if they have a poor prognosis. But there are a few cases where maxillary central incisor might be missing / avulsed / need extraction due to bad endodontic / restorative prognosis.

The manangement of the loss and/or extraction of the maxillary central incisor requires interdisciplinary orthdontic treatment. Carefully planned treatment mechanics and pre-charting of the post-treatment occlusal relationship along with proper group functional occlusal scheme are required for a better and stable final outcome. Thus the treatment protocol and mechanics for such cases are different than the routine mechanics. The adjunct periodontal, restorative and prosthodontic procedures require correct timing and need to be executed with perfection.

This presentation will discuss a rationale for extraction of maxillary central incisor, space closure mechanics; and highlight some of the problems and pitfalls with their successful management with presentation of clinical cases.

Abstract

As surgery first becomes more popular, the boundaries of the surgeon and the orthodontist becomes more intricately inter-twined when it comes to planning of such cases. It is therefore important that fundamental principles of both orthodontic and surgical aspects are understood by both for the successful planning of such cases. The paradigms of ortho-orthognathic management will be discussed and strategies to ensure successful and predictable outcomes in Surgery First.

Abstract

The profession of orthodontics is constantly under siege from differing forms of Industry Threats, Challenges and Disrupters. It is imperative that orthodontic professionals and professional societies or associations provide clear, honest, evidence-based information regarding orthodontic treatment to the public. In my opinion, it is a responsibility of professional associations or societies to mount public education campaigns to counter the Industry Threats, Challenges and Disrupters to the professional provision of orthodontic care. The Australian Society of Orthodontists (ASO)Public Education Campaign is at the forefront of public education on the benefits of seeking treatment from a highly educated orthodontist and providing the public with warnings regarding unconventional treatments and treatment delivery systems. This presentation will explore some of the Industry Threats, Challenges and Disrupters and display elements of the ASO's campaign to educate the public of the benefits of seeking an orthodontist's opinion and the risks of unconventional orthodontic delivery systems.

Yuko Shimizu
Dental Hygienist, Perth, Western Australia

Yuko Shimizu currently works as a dental hygienist at The Orthodontist, Perth's leading orthodontic clinic. After graduating from Tokyo Dental Association Dental Hygienist College in her homeland, Japan, in 1998, Yuko's passion for travel brought her to multicultural Australia, where she fell in love with the laid-back lifestyle. In order to live and work in Australia, Yuko undertook extensive English language studies before gaining her Associate Degree in Dental Hygiene from Curtin University of Technology in 2008. In addition to her duties in the practice's two Perth metropolitan clinics, Yuko is also part of a travelling team providing orthodontic treatment to patients in remote communities. Her daily interaction with patients from various cultural backgrounds has added a new dimension to Yuko's technical skills as a dental hygienist, making her a value member of the orthodontic services team at her practice. Yuko is a member of the Dental Hygienists Association of Australia.

Abstract

While technical skills as a dental hygienist can be transferred across borders, as a Japanese trained dental hygienist, the cultural exposure of working in Australia has been the biggest challenge, but also the most rewarding aspect of my career to date.
Less than 2% of Japan's population is non-Japanese, so the patient profile is very similar across the country. In Australia however, almost a third of the population are born overseas, every day brings new opportunities to learn more about the people we treat, and how to cater to their needs to ensure that they receive the very best of care.
Working in this environment has taught me to appreciate ethic and cultural diversity, how to communicate with individual patients accordingly, and how to respect the cultural sensitivities of my patients and colleagues in the clinic.
Through sharing my experiences, this presentation will discuss how cultural exposure and understanding can improve technical performance as a dental hygienist - something that simply can't be taught in a structured learning environment.

Abstract

Recently, many adult patients who are seeking orthodontic treatment visit orthodontic offices. Although there is regional difference, it is said that percentage of adult patients is about 20~30%.
Different from child or teenage patients, providers in orthodontic offices need another consideration for adult patients. The government survey in 2011 found the prevalence of moderate to severe periodontitis in 25~54 years of age were 18~34% in Japan.
Periodontal disease is called as silent disease, so it is difficult to be aware of involved this disease for patients. And for us, it is hard to evaluate condition of gingival tissue with just visual examination.
Oral cavity harbors more than 700 kinds of resident microbial species, they are usually as good bacterium and keep balance between periodontal tissue and microbiota. However, periodontal disease occurs due to break down of this equilibrium.
After placement of orthodontic appliances, plaque accumulation by inadequate oral hygiene enhances gingival inflammation such as reddish and bleeding. This kind of situation results in increasing periodontal pathogenic anaerobic microbial species in the subgingival site.
As above, we need to recognize patient´s history of periodontal treatment and know state of periodontal tissue before or during orthodontic treatment.

Main points are following,
Equilibrium between periodontal tissue and microbial species
Subgingival microbiota after placement of orthodontic appliances
Necessity of monitoring of periodontal tissue during orthodontic treatment
In order not to develop to periodontitis from gingivitis

Abstract

Orthognathic surgery has been used as an approach to correct significant dentofacial deformities. Orthognathic surgery primarily addresses jaw discrepancies in the 3 planes of space improving the facial esthetics and occlusion. However, in some instances the surgery may negatively affect some facial elements such as the nose or in some instances may not obtain the optimal facial esthetics such as addressing malar deficiency. Complementing the bimaxillary movements with esthetic adjuncts maximizes the facial esthetics results from orthognathic surgery.
This lecture will highlight the combination of orthognathic surgery with adjunct surgical procedures such as mandibular angle, malar, and chin implants, microfat grafting and lipectomies. Rhinoplasties a few months after the surgical procedure will be discussed as an option to refine the surgical outcomes. The virtual planning, sequence of procedures and execution of the surgery will be presented.

Abstract

Occlusion has been considered for years as one of the major aetiological factor causing Temporomandibular Disorders (TMD). Nevertheless, at now the associations reported are few, weak and not consistent across the studies. Hence at today, the role of occlusion in the aetiology of TMD has not been clearly addressed and therefore it should not be overstated. Actually, occlusion represents a highly complex specialized system of integration of neurological signalling originating from periodontal, dental, and soft tissue mechanoreceptors. This complex framework of information is continuously elaborated by the central nervous system, in order to adjust and refine jaw position and movements, according to peripheral inputs. Therefore, the board concept of occlusion does not involve only the peripheral input (the tooth to tooth contact), but also the way the same stimulus is interpreted by the brain of each individual. Hence, the central nervous system changes (sensorimotor neuroplasticity) are the major factors to determine how well an individual adapts to the occlusal and oral alteration that can result from any dental treatment.
Therefore, it seems crucial to correctly understand the connection between occlusion and TMD, but the paradigm shift requires moving to a more comprehensive interpretation of the occlusion and of the maxilla mandibular relationship. As no proven causal relationship exists, the role of malocclusion in the aetiology of craniomandibular disorders should be considered very limited. Instead, patients occlusal awareness and concerns have to be seriously accounted by clinicians during general and dental examination as specific group patients might develop iatrogenic maladaptive behaviours.

Abstract

It is known that the risks of systemic disease increase by losing teeth, possibly due to periodontitis which closely relates with malocclusion and bruxism. Past studies have suggested that occlusion influences general health. Particularly, it was reported that patients with skeletal Class III had more gastroesophageal reflux disease (GERD) symptoms than normal subjects, possibly due to low salivation. Regarding sleep bruxism, several negative influences on the dentofacial region are known, including tooth wear, TMDs such as myofascial pain, hypertrophy of the masseter muscle, and grinding sounds leading to sleep disturbance of family members. At present, there is no causative treatment although teeth can be protected from bruxism by wearing a splint. A previous study in 2003 found that swallowing was related with sleep bruxism, which inspired the hypothesis that gastroesophageal reflux (GER) may cause sleep bruxism. Surprisingly, the associated factors of sleep bruxism and the associated factors of GER are nearly matched. After examining the relationship between sleep bruxism and GER, it was found that intra-esophageal acid stimulation, which was a model of gastroesophageal reflux (GER), caused more numbers of swallowing and bruxism episodes. In addition, the other previous studies revealed that esophageal acidification causes sleep bruxism in normal subjects, and that the administration of a PPI (gastric acid secretion inhibitor) reduced the frequencies of bruxism episodes. Recent meta-analysis revealed that GERD is the most associated risk factor of sleep bruxism in adults. This suggests that GER-caused bruxism may be a physiological response to protect the esophagus.

Abstract

Bruxism is a repetitive jaw-muscle activity with two distinct manifestations, awake bruxism and sleep bruxism. Awake bruxism, i.e. the habit to clench the teeth during daytime, could simply be a learned habit that increases in frequency and duration under certain conditions, such as stress and anxiety. Sleep bruxism is a 'sleep-related' motor activity that is commonly observed also in non-bruxers. This activity increases in frequency in the presence of some triggers, such as stressors, anxiety, smoking, caffeine intake, heavy alcohol drinking and medications.
The diagnosis of bruxism is challenging and self-reports of bruxism patients obtained during interviews may be invalid. Tooth wear is not a proof of ongoing SB bruxism because of the natural variability of bruxism and wear could have occurred in the past. It is also incorrect to related the severity of tooth wear to the severity of bruxism activity.
As the vast majority of bruxing episodes last only a few seconds, the total sleep bruxing time per night amount to a few minutes. This raises the question whether this intermittent and short-lasting muscle activity is sufficient to be so deleterious as normally thought by dentists.
Patients with awake bruxism or sleep bruxism may present to orthodontists posing some challenges for the treatment. What does an orthodontist need to know about bruxism, and what are the implications of bruxism for the management of orthodontic patients? This lecture will summarise our current understand of bruxism, from an orthodontist's perspective.

Abstract

Orthodontists can do amazing things for bones and teeth, but what is actually going on? I have been asking the fundamental question about special bone cells called skeletal stem cells, and what these cells do for us over the last decade. Skeletal stem cells are the cells that can produce a variety of bone cells with important functions in bone health and diseases. Our recent findings are beginning to unravel their unique properties: these stem cells are diverse, malleable and local in nature. For example, we have identified skeletal stem cells in the resting zone of the growth plate cartilage - these stem cells look exactly like chondrocytes that usually make cartilages, but acquire special features of life-long self-renewal. The question is how a small number of skeletal stem cells are maintained in adulthood: our more recent findings point to the possibility that some types of functionally dedicated mature bone cells, such as those residing in bone marrow space termed bone marrow stromal cells, can revert into stem cells under special conditions. In this lecture, I will present the current concept on skeletal stem cells, and how they can help our daily and future orthodontic practice.

Abstract

Non-syndromic tooth agenesis or isolated hypodontia is the most common human malformation. The prevalence of the condition ranges from 1.6% to 9.6% in different populations. Non-syndromic tooth agenesis has been reported to be associated with heterozygous mutations in MSX1, PAX9, WNT10A and WNT10B. MSX1 and PAX9 are the most reported genes associated with agenesis of the premolars and/or molars. Oligodontia patients with PAX9 mutation exhibit clear phenotype with agenesis in molar region, on the other hand, the patients with mutations in MSX1 gene show various phenotypes including agenesis of the premolars.
Previous functional analyses for detected mutations have been examined with cell culture system because of the methodological limitation. It means that the causality of the reported mutations detected in small pedigrees or unclear phenotypes is not always reliable. Recently, more than half of patients with hypodontia were reported to have WNT10A mutation without any functional analysis of the gene, however, the causality is statistically questionable. For such a reason, the genotype/phenotype correlation is occasionally in a state of chaos.
The presentation will show the mutation detection of the genes for the patient with oligodontia using next-generation sequencing technology-based targeted panel sequencing analysis which improves the molecular diagnosis in target genes. The presentation will also make clear the causality of pathogenic SNVs using genome editing technology in mice. This strategy showing tooth phenotype can be a useful method to verify genotype/phenotype correlation of human disorders. For Msx1 gene, in vivo functional analysis for each conserved domain will also be presented.

Abstract

Young patients with a Class III malocclusion and maxillary deficiency are treated primarily with facemasks. However, because the force is applied to the teeth, the inevitable mesial migration of the dentition can result in anterior crowding and the need for a subsequent extraction therapy. Furthermore, the desired skeletal effect of this commonly used approach often turns out to be less than expected. To increase the advancement of the maxilla, facemask therapy is often combined with rapid palatal expansion (RPE) since stimulation of the midface sutures is expected. Temporary Anchorage Devices (TADs) can be inserted in the palate to avoid mesial migration of the upper molars when using a facemask and to minimize tipping or periodontal damage to the bicuspids /deciduous molars when expanding the maxilla. The author will present early Class III cases treated with the help of TADs and the skeletal and dental changes one will expect with the use of this device. After this lecture, the attendees of this lecture will be able to identify the type of Class III patients suitable to be treated with facemask, RPE and TADs; identify the various factors such as growth pattern, growth potential and the severity of malocclusion that can affect the treatment outcome with this appliance; and learn how to design and fabricate RPE with TADs that can be used in conjunction with a facemask.

Abstract

Mandibular prognathism and/or maxillary hypoplasia are the two most common features in pubertal patients with Class III malocclusion. Maxillary hypoplasia includes sagittal and/or vertical deficiency. The orthodontic camouflage treatment or orthopedic maxillary protraction in growing Class III patients usually focuses on the sagittal improvement of anterior cross bite and maxillary growth, but seldom on the maxillary vertical deficiency and control of mandibular growth. Furthermore, the subsequent relapse & cease of maxillary sutural growth after maxillary protraction, and outgrowth of mandible during puberty are substantially unsolved problems. Although we are not able to reduce the growth amount of mandible, the purpose of this presentation is to propose innovative thoughts and clinically feasible techniques for redirecting mandibular growth inferiorly and even posteriorly, and at the same time redirecting maxillary growth anteriorly and inferiorly by surface remodeling of maxilla (periosteal growth of maxilla). The rationales, clinical studies, and cases illustrations will be presented.

Abstract

Two female patients presented with gummy smile, maxillary dentoalveolar protrusion and total vertical maxillary excess, retroclined incisors, and increased overbite received orthodontic camouflage with straight wire mechanics by general dentists. The treatments caused severe bowing of upper occlusal plane which aggravated the gummy smile and had led them to seek specialist care. They were successfully managed by orthodontic camouflage and combined surgical orthodontic treatment, respectively, in conjunction with the application of miniscrews on straight wire mechanics. Aggravation of gummy smile by straight wire mechanics, use of visual treatment objective to differentiate between orthodontic camouflage and surgical cases, and LeFort I segmentalization were discussed.

Biology of tooth movement, biomechanics, craniofacial anomalies

Abstract

The achievement of a planned tooth movement is the result of the interaction between variables related to the orthodontist and variables related to the patient. The orthodontist plans the individual biomechanical system in relation to the centre of resistance of one tooth or groups of teeth. It is known that the location of the centre of resistance varies according to the patients' anatomical characteristics; the anatomy of the supporting tissues and the shape of the roots. The quality of the supporting tissues in terms of bone density has seldomly been taken into consideration as potential variable that could influence the location of the centre of resistance. Surgically facilitated orthodontic tooth movement is one of the various attempts of orthodontists to influence patients' response to enhance tooth movement rate. The principle is based on the local acceleration of bone remodelling activities occurring in bone repair processes, where bone density is initially decreased. Accelerated bone turnover in animal models has shown to increase tooth movement rate and the application of a single force induces a controlled rather than an uncontrolled tipping, as would under normal bone turnover conditions. A Finite Element analysis of tooth movement after corticotomy revealed that translation in corticotomized teeth occurs at a larger M/F ratio compared to normal bone turnover. In order to achieve this, a bigger moment needs to be inserted into the wire.

Abstract

This presentation will explore how recently published evidence (systematic reviews and randomized clinical trials) focused on impacted teeth has impacted my day to day clinical decisions when faced with a potential impacted canine. The following questions will be explored:
Does CBCT make always a difference? - diagnosis focus
Is there a better outcome if a specific surgical exposure approach is used? - management focus
Is it always worth to attempt to tract the impacted tooth down? - prognosis focus
Can early extraction of deciduous canines reduce the chances of permanent canine impaction? - prognosis focus
Clinical cases will be shown to facilitate the conversation.
