Can we practice evidence-based orthodontics? Dealing with uncertainty...
Thursday 8.45am
In this presentation I will discuss the dilemma of attempting to practice evidence-based orthodontics. I will use examples from my own work on how research reduces, or increases, clinical uncertainty. While this presentation will be based on orthodontic examples, I will also discuss other areas of dentistry to illustrate that orthodontics is not the only area of work in which recognising and dealing with uncertainty is becoming increasingly important particularly with respect to the regulation of dentistry.

In the land of no evidence; is the Salesman King?
Thursday 1.30pm
Over the past few years in dentistry advertising by both the supply companies and individual practitioners has been increasing. This is directed at both the promotion of products and the introduction of new philosophies. In this lecture I will evaluate the effect of advertising, that is not supported by scientific evidence, on current practice. I will also discuss the "teaching" of orthodontics and other treatment to general practitioners by short courses from a regulatory viewpoint.

Social media driven orthodontics: quacks, healers and blogs
Thursday, 2.15pm
Over the past few years in dentistry advertising by both the supply companies and individual practitioners has been increasing. This is directed at both the promotion of products and the introduction of new philosophies. In this lecture I will evaluate the effect of advertising, that is not supported by scientific evidence, on current practice. I will also discuss the "teaching" of orthodontics and other treatment to general practitioners by short courses from a regulatory viewpoint.

How do you read a trial and systematic review?
Friday 11.00am
Contemporary research methods are more complex. As a result, it is becoming more difficult to interpret and understand many of the trials and systematic reviews that are being published. In this presentation, I will provide information on methods of understanding research, using examples from the literature.
Pre reading recommended: document 1 and document 2

Adolescent class II treatment - twin blocks, mandibular growth and systemic reviews
Friday 11.45am
Most research has concluded that the best time to provide functional appliance treatment is during the pubertal growth period. However, there is still uncertainty on the type of appliance that we should use. I will provide evidence from clinical trials and systematic reviews that should underpin our treatment decisions.

Socio-psychological effects of orthodontic treatment - are we interested and do we care?
Saturday 9.45am
The most common reason for providing orthodontic treatment is to improve the appearance of the face and teeth. While this assumption is logical there is limited research into the effectiveness of orthodontic treatment on psychosocial status. I shall describe current research into this area and raise fundamental questions on the value of orthodontics on psychosocial benefit. Finally, I shall discuss whether we simply need to correct the aesthetic appearance of the front six teeth "the social six" as opposed to achieving a perfect occlusion.

Early Class II treatment. Does the cost outweigh the benefits?
Saturday 11.45am
In this presentation I will outline the results of my own research into early Class II treatment. In addition, I will present data from our recently updated Cochrane review into Class II treatment. This will involve a consideration of important factors such as self-esteem, treatment duration, reduction of trauma and overall cost.

Sunil Kapila

Sunil earned his Bachelor of Dental Surgery degree from the University of Nairobi (Kenya) in 1981. Afterwards, he was a dental officer at the Kenyatta National Hospital in Nairobi for two years and then became a clinical instructor and tutor in orthodontics at the University of Nairobi Dental School. He came to the U.S. in 1984 as a Fulbright-Hayes scholar to obtain a master's degree in orthodontics which he received three years later from the University of Oklahoma. In 1994, Dr. Kapila was awarded his doctorate in oral biology which he earned while teaching at UCSF. He began teaching there part-time in 1988, and become a full-time Assistant Professor in 1993. He was tenured in 1999 and was appointed as Chair of the Division of Orthodontics in 2000 and named the first Eugene E. West Endowed Chair in 2001. He was recruited to the University of Michigan in 2004 and served as the Chair of the Department of Orthodontics and Pediatric Dentistry and the Graduate Orthodontics Program Director from 2004-2015.

His practice philosophy includes preadjusted appliances using continuous archwire or segmented mechanics and contemporary wires. He teaches in the graduate orthodontic clinic on Tuesday afternoons and teaches biomaterials and biomechanics to the residents. He also provides lectures on biomechanics and TMJ pathobiology at national and international meetings. Dr. Kapila is the recipient of several research awards including the AADR Hatton Award in 1994 and the AAO Milo Hellman Award in 1995. He was also awarded the Outstanding Alumnus Award by the Department of Orthodontics at the University of Oklahoma in 2007.

Orthodontics in 5D: enhancing treatment efficiency and outcomes
Thursday 10.45am, Friday 9.00am, 1.45pm, Saturday 9.00am
The long duration of treatment is one of the biggest limitations of orthodontic therapy. For this reason, there is a constant demand for methods that expedite tooth movement and increase efficiency of orthodontic treatment. Thus surgical methods that have recently regained visibility and the introduction of new devices attest to the continued interest in enhancing tooth movement rates. However, there is limited evidence for the efficacy of many of these methods to expedite tooth movement. In his lecture, Dr. Kapila will provide a historical perspective and current evidence for methods proposed to enhance treatment efficiency. He will also describe approaches to optimally utilize 3D information and biomedical approaches to enhance both orthodontic treatment efficiency and outcomes. Application of strategies of optimal 3D diagnosis, treatment planning and implementing biomechanics in 3D will contribute to success in the fourth dimension of time by delivering efficient treatment and the in fifth dimension with improved treatment outcomes. The audience will learn about:

• The current status of and evidence for surgical and mechanical approaches to expedite tooth movement
• Novel approaches using biomedical agents to enhance tooth movement rates
• The application of simple and effective biomechanics in 3D to optimally control tooth movement and anchorage in 3D to improve treatment efficiency and outcomes
• Using 3D Image-aided treatment and biomechanics for improved success and efficiency in retrieving impacted and transposed teeth

3D image aided treatment of impacted and transposed teeth
Saturday 1.45pm
Three-dimensional (3-D) imaging rendered by Cone Beam Computed Tomography (CBCT) facilitates refined diagnosis and enables fine-tuning of treatment plans in specific types of cases. In patients with impacted and transposed teeth, the information derived is particularly important in enhancing efficiency of treatment, rates of success and minimizing collateral damage during treatment. In his talk, Dr. Kapila will present the indications and uses of CBCT imaging in diagnosis and treatment planning for impacted and transposed teeth, including protocols for communicating with the surgeon to achieve optimal surgical access, bond placement and soft tissue support, and the utilization of this information to implement efficient three-dimensional mechanics. He will also discuss the use of refined spring designs to tract the teeth along the shortest path through bone while minimizing damage to roots of neighboring teeth.

The attendees will learn about:
1. The use of CBCT in refining the diagnosis of impacted and transposed teeth.
2. Defining 3-D treatment plans, surgical access, bond placement and biomechanical objectives for impacted and transposed teeth.
3. Designing and implementing optimal traction auxiliaries for 3-D tooth control while minimizing damage to neighboring teeth and adverse movements of anchor teeth.
