The Orthodontics Class of 2030 and Beyond: Future-proofing a New Generation of Orthodontists Amid Technology Trends
Kelvin Foong

According to Wikipedia, “future-proofing is the process of anticipating the future and developing methods to minimise the shocks and stress of future events.” In orthodontics where patient care is the primary responsibility in clinical practice, future-proofing an orthodontist means equipping the clinician with cognitive capabilities and skill sets to maintain high quality patient care amid a rapidly evolving practice landscape.

Two questions come to mind: when and how should the community of orthodontists prepare its future generations in the face of an increasing role of digital dentistry in clinical practice and a greater demand for orthodontic services from an adult and older patient population who are more educated but have chronic medical issues? This lecture will explain that future-proofing the new generation of orthodontists starts with the present. It will also discuss what university-based postgraduate orthodontic programmes, professional orthodontic societies, orthodontic departments within hospitals, and the community of private practice clinicians can do, individually and collectively, to future-proof the new generation of orthodontists. This lecture posits that the basic specialty training (BST) phase in university-based postgraduate orthodontic programmes will remain as the standard of educational practice to produce a competent practitioner and suggests “Interdisciplinary Learning” (different from “multi-disciplinary”) as an additional pillar of learning to the already rigorous BST course. Beyond the BST phase, the lecture will share how a “whole of community” approach can also help bring about a future-proofed generation of orthodontists.

Learning objectives

  1. How the Orthodontics Residency Programme at the National University of Singapore produces competent clinicians who can independently plan treatment and manage a wide range of malocclusions with high quality outcomes.
  2. What “Interdisciplinary Learning” is in the context of specialty orthodontic training.

Treating the Anterior Open Bit Patient - The Evidence So Far
Greg Huang

Anterior openbite is challenging to correct, and even more challenging to retain. Many studies have been conducted on the etiology, treatment and retention of these patients. Dr. Huang will review the literature on openbite treatment in three age groups - mixed dentition, permanent dentition adolescents, and adults. He will focus on systematic reviews and meta-analyses, where available, as they represent the best evidence we have. However, much of our evidence on anterior openbite is from observational studies, and better evidence is necessary to improve our understanding of this malocclusion.

Dr. Huang will also review some of his findings from a recently conducted National Network study focusing on adult anterior openbite patients. The study assessed the recommendations of practitioners, the acceptance by patients, the end-of-treatment results, and the stability one year later. Importantly, it included patients treated with two new modalities - temporary anchorage devices, as well as clear aligners.

Learning Objectives

  • The attendee will understand some common strategies employed for anterior openbite patients in various age groups
  • The attendee will be exposed to the systematic reviews and meta-analyses that deal with anterior openbite, and appreciate the limitations of the existing literature
  • The attendee will learn about factors associated with treatment success in adult anterior openbite patients

9.00am - 10.30am
Treatment of Anterior Open Bite - Nuts And Bolts
Chris Chang

Common anterior open bite corrections include extractions and a variety of appliances, such as, high-pull headgear, bite blocks, and elastics. In more severe cases, orthognathic surgery is required to correct the skeletal malocclusion. While surgery proves to be a reliable treatment option, many patients reject it for the prohibitive cost, pain and long recovery time. Recently, buccal shelf screws have allowed orthodontists to treat some of these patients without orthognathic surgery through intrusion of the posterior maxillary molars. They provide a treatment alternative for mild-to-moderate open bite cases without other skeletal contributing factors. This lecture will demonstrate how to properly identify and eliminate the etiology of anterior open bite and create effective strategies to correct it with TADs and extractions.

Learning Objectives:

  • After this lecture, you will be able to accurately diagnose different types of open bite malocclusions.
  • After this lecture you will be able to successfully identify possible etiological factors of different open bite malocclusions.
  • After this lecture you will be able to manage open bite malocclusion based on different etiological factors and patient preference.

Aligner Orthodontics: From Basic Research to Clinical Applications
Tomasso Castroflorio

The demand for minimally invasive solutions led to the development of appliances that combine effectiveness in correcting dental positions with comfort and aesthetics features. Despite the widespread use of orthodontic therapy with clear aligners, their level of efficiency is still controversial. However, the reliability of CAT has increased due to the implementation of the thermoplastic biomaterials and a better understanding of biomechanics applied in combination with the exponential number of biomedical studies.

Systematic reviews on the predictability of orthodontic movements of teeth with aligners showed that bodily movements, in the sagittal and vertical planes are unpredictable.

One of the reasons why the effectiveness of aligners is still under discussion could be the force transmission mechanism. In the traditional system, the orthodontic movement is the result of the interactions of metal wires and brackets to the tooth; conversely, in the aligners system, the forces and moments are generated by the difference between the shape of aligners and the teeth. In addition, the resolution of complex movements demands the use of attachments. The application of engineering knowledge in dentistry with the use of computational techniques has helped to understand oral biomechanics aspects. The finite element method (FEM) is a numerical technique used to perform finite element analysis (FEA) of any given physical phenomenon and is widely accepted for medical purposes. The aim of the lecture is to provide some clinical tips, on the basis of FEAs, in order to increase the predictability of some orthodontic tooth movement with aligners.

12.00pm - 1.00pm
The Difficult Class III Patient
Juan Carlos Perez Varela

This session will cover new frontiers and perspectives in the treatment of skeletal III malocclusions in adults and young adults. Around 60 % of Dr Huan Carlos Perez Varela's patients are adults and a significant percentage of them have skeletal III malocclusions. In this conference Dr Juan Carlos Perez Varela will present cases with different treatment alternatives including a new protocol with local anesthesia and sedation using 3D technology.

Learning Objectives:

  • After this lecture, you will be able to perform an adequate diagnosis of maxillary skeletal hypoplasia in adults and young adults.
  • After this lecture, you will be able to know how to use 3D technology to develop customized appliances.

1.00pm - 2.00pm
Vertical Issues
Joseph Bouserhal

Smile aesthetics is considered as the main objective to fulfill during our orthodontic treatment. In handling our patient’s problem list, we ask frequently ourselves:

  • Do we have to consider the incisor position ONLY in the sagittal plane or more and more in the vertical?
  • Should we have to apply a SYSTEMIZED treatment approach or must we INDIVIDUALIZE our treatment planning?

Our orthodontic philosophy has to consider the initial vertical position of upper and lower incisors at rest and during smiling in order to set up individualized treatment objectives and to attain the best final aesthetic result. Therefore, we have to apply individualized mechanics depending on facial growth pattern, occlusal plane inclination and smile line position.

Learning Objectives:
Attendees of this lecture will be able to:

  • Establish an individualized diagnosis based on the different components of the face.
  • Set-up an appropriate treatment planning according to smile aesthetics need.
  • Apply individualized mechanics depending on facial growth pattern, occlusal plane inclination and smile line position.

3.00pm - 4.00pm
Traditional Mechanics - Relevance in Clinical Practice
Steven Lindauer

Orthodontic practice is changing rapidly. New developments, including improvements in skeletal anchorage and aligner therapy, seemingly pull orthodontists in opposite directions as many patients demand faster treatment, better results, and all accomplished without tooth extractions or surgery. How do traditional treatment strategies and mechanics fit into the changing orthodontic practice of today and how have patient expectations regarding their treatment experience and outcome changed? This lecture will discuss the indications for adopting new orthodontic techniques and approaches to treatment for accomplishing goals that cannot be reached using conventional means. Conventional mechanics require the clinician to predict the wanted and unwanted side effects of appliance activations. Recent research on new methods for making orthodontic outcomes more predictable and reliable while reducing or eliminating unwanted side effects will be presented. Overall, biomechanical knowledge and creativity in appliance design are important tools that can be used dependably by orthodontists to accomplish dramatic changes for patients primarily using traditional mechanics and appliances, sometimes in conjunction with new techniques as indicated.

Learning Objectives:

  • To recognize that patients desire high quality outcomes and that this goal can be achieved with a variety of treatment strategies, techniques, and appliances.
  • To become familiar with current research trends in procedures to make orthodontic treatment more effective and predictable.
  • To know the indications for applying creative strategies using traditional mechanics to achieve desired outcomes efficiently by taking advantage of desirable side effects and avoiding unwanted side effects.

4.00pm - 5.00pm

Managing Difficult Impactions - Optimising Outcome with the Right Tools
John Yau

‘To save or not to save, that’s the question.’

Teeth impaction is one of the most commonly encountered clinical problems which require meticulous biomechanics for saving them, if not surgically removing them eventually.

Temporary anchorage devices (TADs) have been advocated in providing absolute anchorage for orthodontic treatment predictably. The advantage of TADs usage has significantly improved the prognosis and success rate of saving the heavily impacted teeth.

‘To wait or not to wait, that’s the second question.'

The timing of saving the impacted teeth can be as important as the technique in handling the problems themselves.

This lecture aims at demonstrating the versatility of TADs application in those challenging impacted teeth cases, as well as solving the problems without the use of TADs on different orthodontic systems. Careful case diagnosis, treatment planning and the potential complications will be discussed.

Learning Objectives:

  • To understand the therapy of saving impacted teeth on different orthodontic systems
  • To recognize the case diagnosis, treatment alternatives, limitations & complications
  • To design TADs insertion sites & respective biomechanics in different scenarios

The Quest For Quality - Tips, Tricks And Hacks
Ute Schneider-Moser

The fast technological and technical progress during the last years has considerably changed the face of orthodontics in terms of diagnosis and treatment planning with a much greater focus on dental and facial aesthetics than in the past. However important a ‘great smile’ is to our patients, we must not forget that function and maintainability of our treatment outcomes should not be sacrificed to bells and whistles and to meeting mere cosmetic demands which are subject to fashion trends and change over time.

Proven treatment principles such as respecting the patient’s individual physiognomy, skeletal relationships, and the bony and soft-tissue envelope of the dentition still hold true today, even if rapid palatal expansion or whole-arch distalization supported by skeletal anchorage, corticotomies coupled with bone and soft tissue grafts, and photobiomodulation for faster and less painful treatment gain more and more momentum - pushing the boundaries of conventional orthodontics.

However appetizing and promising these new-age approaches may be, it is important to understand that a thorough diagnosis based on sound clinical examination and analysis of good quality standard records, a comprehensive differential treatment plan, correct timing, considerate application of simple but efficient mechanics guided by common sense, and a critical review of every single treatment result is still more important than a fancy virtual simulation for achieving the so-called ‘ideal smile’ and the insertion of a high-tech digitally planned and printed appliance as heavily advertised in every media. Instead, careful and selective implementation of the recent advancements in our field, providing complex treatment by a skilled and well-orchestrated interdisciplinary team, and continuous synchronization of the clinician’s experience with the latest evidence based on sound high-quality research is the key to excellence.

Learning Objectives:

  • To understand which proven concepts to achieve excellent treatment results on a regular basis are still relevant today
  • To learn which recent advancements should be implemented to continuously improve orthodontic treatment results
  • To understand that orthodontics is not a stand-alone specialty anymore, but should be considered as an integral part of interdisciplinary patient-centred care

4.00pm - 5.00pm

Dialogue Session "Demise Of The Bracket - A Looming Certainty?"
Kau Chung How, Chng Chai Kiat, Nikhilesh Vaid, Simon Graf, Greg Huang, Chris Chang, Tommaso Castroflorio

We are standing at the precipice of changing trends in our orthodontic specialty today. The many recent advances in technology like Digital Orthodontics, Artificial Intellignce (AI), Clear Aligners etc and their potentially disruptive effects may change the practice of Orthodontics as we know it. Will the advent of AI and big data analytics coupled with an ever-changing consumerism behaviour signal the demise of the bracket? Is this piece of plastic overtaking a position in which the orthodontist has reigned supreme with his bracket and wire- bending skills? Let this panel of experts give us an insight and perhaps gaze into the crystal ball of our specialty.

8.30pm - 9.30pm
Artificial Intelligence Driven Orthodontic Care: A Flight to Utopia?
Nikhilesh Vaid

AI applications in Orthodontics are relatively young but growing at a rapid pace. This presentation aims to:

  1. Explain conceptually how AI algorithms work.
  2. Classify AI applications and their scope in orthodontics.
  3. Asses clinical scope, performance and risks associated in therapeutics.
  4. Propose an outline for audit of AI applications in orthodontics.

The lecture will explain how AI is a set of tools for problem-solving that can assist orthodontists with extra powerful and applied tools to provide better standards of care. AI can assist orthodontists to choose the best way to move a tooth or group of teeth, but AI today completely ignores the existence of oral diseases, does not fully integrate facial analysis in its algorithms, and is unable to consider the impact of functional problems in treatments. The lecture will also deliberate the risks associated with AI application. As AI enters practice, clinicians need to know how law will assign liability for errors that arise from interaction between algorithms and practitioners. These issues are likely to arise sooner rather than later. Responsibility and the varied scope of these applications will also be deliberated.
