Management of Complex Situations Due to Missing Teeth in the Smile Area
Ute Schneider-Moser

Patients affected by missing teeth in the aesthetic zone due to agenesis or transpositions, impacted or retained teeth, tooth malformations such as dilaceration or fusion, and the entire range of dental trauma may sometimes require unusual treatment approaches. The therapeutic challenge in these patients is to select 1. the most appropriate orthodontic strategy, possibly without extremely sophisticated mechanics, 2. to keep treatment time within acceptable limits for not risking iatrogenic damages, e.g. major root resorptions and 3. to avoid the necessity for a future extensive implanto-prosthodontic rehabilitation. An interesting array of complex clinical patients who were treated by application of simple, but efficient mechanics will be presented.

Learning Objectives:

  1. To understand the pros and cons of space closure and opening for missing teeth in the anterior maxilla
  2. To develop efficient treatment plans without particularly sophisticated mechanics
  3. To handle situations with extreme hard and soft tissue defects due to traumatic tooth loss in the smile aera

Managing Complex Orthodontic Malocclusions with and without TADs
Ravindra Nanda (Remote Speaker)

Complex malocclusions demand a different set of additional considerations in diagnosis, treatment planning and execution of mechanics plans. The patients are often adults with missing teeth, severe deep and open bites with transverse, anteroposterior and vertical problems. This presentation will describe use of TADs and their application for various movements such as distalization, space closure, and en masse movement of teeth.

Learning Objectives:

  • To learn best sites for TAD application
  • To understand biomechanic considerations for complex malocclusions
  • To learn en masse space closure with TADs

11.30am - 12.30pm
Success and Pitfalls in Clear Aligners Therapy, Using the Clear Correct System
Hironobu Fumino

Ultimately, aligning patients with what they need, is why I choose Clearcorrect®. With the rapid development of digital transformation, comprehensive orthodontic treatment with aligner therapy has become a viable option for many patients. As patients seek easier ways to improve their oral health, aligner therapies continue to develop at brisk speed, to meet their needs.

For orthodontists, providing an effective aligner orthodontic treatment also requires conducting a thorough diagnosis, for visualizing individualized treatment goals and planning. Currently, it’s still impossible to design and make such individualized aligners automatically. AI (artificial intelligence) cannot replace great orthodonists, yet.

Numerous orthodontic treatment methods can be applied for various orthodontic cases, nowadays. Depending on how you plan to treat your patients, options can include Straight Wire Appliances; Lingual Bracket Systems; Temporary Anchorage Devices; Aligner Therapy etc. The choice of mechanics plays a crucial part in any successful treatment.

In my presentation, I will provide possible reasons for both success and failure in treatments, and how I apply clear aligners. I will present several cases of different degrees of malocclusions and oral dysfunction, using Clearcorrect®.

On a personal note, it’s my goal to create as many “Celebrity Smiles” as I can. While treating patients with clear aligners, I hope to help change people’s lives to a happier and healthier one.

Learning Objectives:

  • The importance of the functional unlocking concept for oral dysfunction.
  • The effect of treatment results with Clearcorrect® clear aligners.
  • Strategies for the proper choice of clear aligners with Clearcorrect®.

Management of Bone Loss, Ankylosed Teeth and Facial Asymmetries due to Trauma
Ali Darendeliler

It is always challenging to treat cases with ankylosed or missing teeth due to trauma, not only because missing teeth need to be replaced but also trauma mostly causes bone loss, and this makes their management difficult especially in young patients. Management of trauma cases will be discussed in terms of treatment timing, types of treatment and possibilities. Ankylosis of anterior teeth in early ages due to trauma is also quite frequent and causes, aesthetic, functional, retardation of vertical growth and management problems. A new protocol for alveolar distraction of ankylosed upper incisors which was recently introduced at the University of Sydney will and management of jaw asymmetries due to trauma will be described and discussed.

Learning Objectives:

  1. Consequences of trauma to the teeth and / or jaws
  2. Management of tooth and bone loss in different ages
  3. Management of ankylosed teeth

3:30pm – 4:30pm
Keynote: Bonded Retainers - Everything You Wanted to Know But Were Too Afraid to Ask?
Simon Littlewood

Bonded retainers are one of the most controversial topics in orthodontics. Some clinicians love them and regard them as the best way to maintain stability after treatment with less compliance from patients. Other clinicians have concerns about unwanted side-effects and problems of long-term maintenance.

This talk will explore the evidence behind the use of bonded retainers, how they compare to other methods of retention, as well as exploring the different types of materials, adhesives and techniques for their placement to reduce bonded retainer failures.

Dr. Littlewood will provide an entertaining and clinically-relevant practical, evidence-based guide to the use of bonded retainers that is relevant to all orthodontic clinicians.

Learning Objectives:

  1. Be aware of best current evidence comparing bonded and removable retainers
  2. Be familiar with different bonded retainer materials and the evidence that supports their use
  3. Learn practical techniques to reduce bonded retainer failures

4:30pm – 5:30pm
Pre-operative Anxiety and the Orthognathic Patient
Florence Kok

Orthognathic treatment involves the use of orthodontics and maxillofacial surgery to correct severe dentofacial discrepancies and has the potential to significantly benefit patients. However, research indicates that patients awaiting orthognathic surgery often experience increased anxiety, and this may result in slower recovery and more post-operative symptoms which can negatively affect the patient’s satisfaction with treatment. It is therefore important to identify factors that the clinical team may influence to minimise patient anxiety and enhance the treatment experience.
Drawing from Dr Kok’s PhD research involving a cohort of Singaporean and UK patients, a number of factors associated with pre-operative anxiety in orthognathic patients will be discussed, along with potential clinical applications on managing this anxiety.

Learning Objectives:

  1. Understanding patient anxiety in the approach to orthognathic surgery
  2. Highlighting potential aspects for consideration in the clinical implementation of strategies to manage patient anxiety prior to surgery

8.30am - 10.00am
Keynote: The Digital (R)Evolution?
Ute Schneider-Moser

Despite the ongoing ‘digital revolution’ in dentistry and in particular in orthodontics, the principles of comprehensive treatment remain still valid today. Without any doubt, 3D-technology is helpful for acquiring more diagnostic information, for planning treatment and, especially for the interdisciplinary patient, to continuously exchange records and to communicate with the treating dental specialists and the patient. Moreover, temporary anchorage devices have widened the range of orthodontic tooth movement and being able to substitute fixed braces with clear aligner systems will enable the orthodontist to convince the more aesthetically demanding adult or adolescent patient to undergo treatment.

No matter how promising these new technologies may be, they are only tools and cannot substitute traditional principles and proven strategies for comprehensive treatment planning with due respect for the patient’s individual situation and by applying sound biological and biomechanical knowledge. Clinical examples to illustrate this concept will be presented.

Learning Objectives

  • to understand the advantages of implementing digital technology in orthodontics and dentistry in general
  • to acknowledge that proven traditional concepts are still valid despite digital innovations

Managing the Temporomandibular Joint: Pathology, Treatment and Future Innovation
Kau Chung How

The temporomandibular joint (TMJ) represents a complex articulation system that connects the jaw bones to the cranium. In times of dysfunction, it can be a challenging problem for the dental team. Orthodontists play a role in the diagnosis and management of TMJ disorders as they have an ability to change the occlusion through selective tooth movement. This lecture will describe the current evidence on TMJ disorders and outline new methods in the management of patients who seek treatment in the clinical setting. Some new 3D imaging techniques and clinical treatment outcomes will be presented to the audience. New techniques including 4D jaw tracking will also be described.

Direct Printed Orthodontic Appliances: Where Are We Now?
Simon Graf

So far Simon Graf was known for his 3D metal printed orthodontic appliances, but now, as new materials are emerging, he continues to integrate them in the orthodontic workflow.

In the first part, he will focus on 3D metal printed appliances in combination with mini-implants. He will show the appliances from planning to printing, including post-processing, to the insertion in the mouth.

A very important part, insertion guides for mini-implants, will be covered as well.

In the second part, he will talk about direct printed aligners and removable functional appliances. Simon Graf will show some cases with direct printed aligners and functional appliances, and how to plan and produce them.

There will be no new aligner-protocol, but many new approaches for direct printed aligners and its possibilities to include other elements, not just attachments.

Learning Objectives:

  • How to plan and connect 3D metal printed appliances with TADs
  • Planning of mini-implant insertion guides
  • How to print aligners directly without cast

Paediatric Obstructive Sleep Apnoea, An ENT's Perspective
Dawn Teo

The incidence of Sleep disordered breathing (SDB) is on the rise. Snoring may be indicative of a more severe problem like SDB. SDB is associated with multiple morbidities. The role of dentistry is important in identifying and managing patients with OSA. The treatment of SDB often involves combined approach involving ENT and dental. The ENT role involves a comprehensive assessment of the airway. A nocturnal attended sleep study can be done to confirm the severity of OSA. There are multiple ENT causes of OSA in children. The most common cause of pediatric OSA is adenotonsiller hypertrophy. As such the first line treatment of paediatric SDB is adenotonsillectomy (T&A). CPAP is offered for those not amenable to surgery, or when there is relapse of recurrent symptoms. However, it is poorly tolerated in the paediatric population. A dynamic assessment of airway may be needed in complex cases or recurrent cases. There are multiple challenges faced in management of SDB in children. However, early intervention has been shown to reduce the morbidities associated with OSA.

Learning Objectives:

  • The incidence of Sleep disordered breathing (SDB) / OSA in the paediatric population is increasing.
  • Early intervention reduces the morbidities associated with sleep disordered breathing.
  • The role of dentistry is important in identifying and managing patients with OSA. The treatment of SDB often involves combined approach involving ENT and dental.

Multidisciplinary Treatment of Obstructive Sleep Apnoea: The Key to Precision Therapy
Shaun Loh

This session will cover the clinical assessment of patients with Obstructive Sleep Apneoa from a dental perspective. The speaker will cover how treatment strategies can be tailor made for CPAP failures to target the primary issue. Strategies being discussed include: oral appliance selection combined with dental ENT experience, orthognathic surgery in skeletally restricted patients, soft tissue ablation in soft tissue hypertrophy and hypoglossal nerve stimulation in poor muscle tone. The speaker will share several case studies of patients who have benefited from a dental-ENT management strategy to illustrate the above treatment strategies.

Role of the Orthdontist in the Surgical Management of Adult Obstructive Sleep Apnoea
Lye Kok Weng

Obstructive Sleep Apnea (OSA) has been gaining prominence in the last 30 years as a chronic medical condition with multiple serious health implications. There are a large variety of surgical procedures that are performed for OSA treatment. Traditional orthognathic surgery has been used to treat Obstructive Sleep Apnea for the last 25 years. To date, the Maxillomandibular Advancement (MMA) is one of the most efficacious surgical procedures to manage OSA. Several modifications to the basic orthognathic design and adjunctive procedures have been used to improve the success rate and manage the potential complications.

Orthodontic therapy is an important part of most MMA procedures. A good understanding of the different demands of this group of patients and collaborative partnership between the surgeon and the orthodontist is crucial. Appropriate orthodontic planning and preparation will aid in achieving timely and predictable surgery and good overall results.

Learning Objectives:

  • Basic information about OSA
  • Understand the role of Orthognathic Surgery in treatment of OSA
  • Understands the orthodontic requirements of MMA treatment

11.30am - 12.30pm
TAD-supported Maxillary Expansion and its Effects on the Airway
Lee Kee-Joon

Respiration and breathing is essential to life. Accordingly, airway management recently gained attention in the clinical orthodontics field. It has been claimed that in cases of transverse problems maxillary expansion not only increases the dental arch dimension but also nasal airway volume. Either surgical or nonsurgical maxillary expansion has been suggested as favorable to nasal airway enhancement. However, several points have to be empirically examined to advocate the actual effect of maxillary expansion. First of all, the biomechanical aspect of the expander design and related clinical outcome reveals possible limitation of conventional RPE and surgically assisted RPE in terms of airway volume. Therefore, the expander design and expansion protocol have to be clearly understood. Secondly, the conflict between the airway and facial esthetics must be discussed. Major expansion in the zygomatic area leads to unfavorable esthetic outcome in the face. Then the question is whether the zygomatic expansion is desirable for facial esthetics. Thirdly, the airway enhancement must be viewed from both nasal and pharyngeal area. Finally, alternative treatment modality for majority of the skeletal Class III discrepancy exhibiting maxillary deficiency must be suggested. In this regard, induced symphyseal remodeling to replace mandibular setback surgery with effective maxillary expansion using MARPE will be extensively demonstrated and explained.

Lunch Talk: Integrating Oral Health Therapists into Your Clinic’s Workflow
Janelle Joy Foo

Do you know how can Oral Health Therapists be seamlessly integrated into your practice’s workflow? This young budding profession can be overlooked and often misunderstood for the roles they are given in the clinic. There is much more that this community of professionals can offer and add value, only if we know how to embrace them and the profession.

2.00pm - 3.00pm
Class III Mechanics with Invisalign for Complex Cases
Kamy Malekian

Class III Malocclusion could be considered one of the most challenging maxilofacial disorder with a mean prevalence of 5,92% among caucassian and higher values (19%) among some Asian regions.

Class III sequential lower distalisation with Invisalign technique is a minimal invasive (Non-Extractions-TAD´s and Surgery) applied in the lower arch in order to treat Class III Malocclusions.

Sequential Attachment Placement on lower distalised molars and premolars increases aligner fitness and lower arch anchorage. With Aesthetic Start Motivation Strategy, patients achieve short-term lower anterior aesthetic results keeping high motivation and full time aligner and elastic wear during total treatment time.

Clincheck planification and clinical tracking is the key factor for successful finishing cases together with high patient compliance aligner wear.

During the presentation we will review comprehensive Class III complex malocclusions in teen and adult patients and Class III complex malocclusions combined with vertical discrepancies such as anterior open bite or underbite cases.

Learning Objectives:

  • Sequential Lower Arch Distalization Protocol
  • Digital workflow from clinical and radiographic diagnosis and iTero scanning post lower wisdom extractions. Clincheck comprehensive planning and clinical tracking for Class III Complex Malocclusions
  • Lower sequential molar distalization is an effective and safe orthodontic alternative with Invisalign technique for Class III dento-skeletal and/or Skeletal Class III Malocclusions

If Pinnochio was an Orthodontic Salesman?
Nikhilesh Vaid

Orthodontic Appliances are no longer just brackets and wires. Technology has ushered in an era of integrated appliance systems, on both vestibular & lingual surfaces as well as removable aligners, that are slowly gaining global acceptance. Integrated systems, however, are marketed by corporations that have financial considerations that sometimes take precedence over science and clinical common sense. This presentation will present a comparative analysis and an experimental clinical audit of contemporary appliance systems and adjuncts from an independent evidence-based perspective.

Learning Objectives:

  • Peruse marketing and advertising claims made by various appliance & adjunct manufacturers.
  • Analyse data from experimental designs evaluating appliance performance on efficacy & efficiency parameters.
  • Compare different appliance systems evaluated based on standard clinical excellence standpoints.
  • Analyse the web presence of Orthodontic information and its effects on orthodontic care protocols.
