Keynote: 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

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

3.00pm - 3.30pm
Tea Break & Visit Exhibition
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

10.00am - 10.30am
Tea Break & Visit Exhibition
10.30am - 11.30am
Keynote: Advances in Aligner Biomechanics, Materials, Attachments and Applications for Surgery First Patients
Ravindra Nanda

During the last two decades aligner treatment has become an important tool to correct various malocclusions. Aligners work in a rather predictable manner with certain types of tooth movements, but complicated movements often do not track as perceived. Limitations are often due to material of aligners and vertical and translatory movements beyond 2-3 mm. Additional devices such as attachments, mini screws and elastics may be required to achieve optimal treatment outcomes. This presentation will describe biomechanics, new materials and role of attachments.

Learning Objectives:

  • To understand aligner biomechanics
  • To learn new aligner materials
  • To understand application of aligners for Surgery First Patients

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.

Tea Break & Visit Exhibition
3.30pm - 4.30pm
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
  • New aligner thinking

8.30am - 9.15am OBSTRUCTIVE SLEEP APNOEA PROGRAMME (OSA)
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.

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

Keynote: The Future of Orthodontic Retention and How to get your Patients to Wear their Retainers
Simon Littlewood

What is the future for orthodontic retention? Dr. Littlewood will explore the fascinating new technological breakthroughs and new materials that may help us to reduce the amount of unwanted post-treatment changes after orthodontic treatment, as well as looking at biological approaches to reducing relapse and the controversial approach of treating patients without any retainers. He will also discuss how the findings of qualitative research is helping us to better understand ways of getting our patients to wear their removable retainers – something that would be helpful for all clinicians who prescribe removable retainers for their patients.

Learning Objectives:

  • Be aware of new materials and technology used to reduce unwanted post-treatment changes
  • Understand the use of biological approaches to reducing relapse
  • Be familiar with methods of improving our patients’ adherence with using removable retainers
