Course Description

The David Turpin Symposium on Evidence-Based Orthodontics has been designed to appeal to both clinicians and academicians. For clinicians, there will be a heavy emphasis on utilizing the current evidence in everyday practice. This includes updates on topics like self-ligation, sleep apnea, vibration, TAD-borne maxillary expansion, anterior openbite, and more. For everyone, there will be lectures on advances in technology, in particular, 3-D imaging and printing. For academicians, the symposium will offer insights into clinical research and the publication process. Additionally, a session is devoted to the critical appraisal of clinical trials, which will assist the researchers who conduct these studies, and the clinicians who will utilize findings from these trials.

More information on Course Topics

Supporting Clinical Decisions with Evidence – Dr. Greg Huang
There are currently more than 300 systematic reviews on orthodontic topics, with more being published every month. The quality of these reviews has steadily improved, and orthodontists should actively utilize these reviews to assist with clinical decision making. Dr. Huang will discuss the evidence for topics like self-ligation, accelerated tooth movement, and TADs, as they relate to the treatment of an actual patient.

Surgical Management of the Transverse Dimension – Dr. Donald Joondeph
Orthopedic expansion of the maxilla can be considered if a patient is young and the midpalatal suture is still patent and amenable to skeletal expansion. As growth diminishes however, the midpalatal suture undergoes morphologic changes that make traditional orthopedic expansion less predictable and the clinician must accept more dentoalvealor change. In that case, one must consider an adjunctive surgical procedure such as surgically assisted expansion, LeFort maxillary surgery or mandibular construction to achieve transverse skeletal alteration. The indications, response and stability of each of these procedures will be illustrated and discussed.

3-D Printing and Lingual Appliances – Dr. Chris Riolo
Throughout our specialty, the transition to digital orthodontics is driving the development of custom orthodontic appliances and 3D printing applications. The false choice that is commonly presented to patients, between therapy with buccal fixed appliances or no treatment at all will be described. This lecture will present examples of custom lingual orthodontics and 3D printing applications to illustrate how esthetic orthodontic care can be delivered to benefit our adult patients. There are a number of compelling reasons why all orthodontic specialists should have some basic capability to employ lingual fixed appliances; this presentation will demonstrate the benefits of using lingual appliances for both the patient and the practitioner.

Surgical Orthodontic Tx for Sleep Apnea – Dr. Jorge Faber
Patients with Obstructive Sleep Apnea Syndrome (OSAS) have an associated risk for cardiovascular events, including arterial hypertension, stroke, and arrhythmias. There is evidence that maxillomandibular advancement (MMA) is the most successful surgical treatment for OSAS. However, MMA through conventional surgical-orthodontic treatment comprises a pre-surgical orthodontic stage, which might not be adequate unless the patient uses a CPAP. A surgery-first approach eliminates orthodontic preparation for orthognathic surgery. This lecture will cover the diagnosis and MMA treatment planning for OSAS under the light of the 14-year clinical experience with surgery first approach. This will be illustrated with a case series to exemplify and contrast the several pieces of evidence available on the literature.

3-D Imaging and Orthognathic Surgery – Dr. Tung Nguyen
With increasing concerns related to the effective use virtual surgery when planning treatment, Dr. Nguyen has some new interesting data. One of these findings concerns the identification of condylar remodeling when condyles are torqued with the surgical movements. Some of the software programs now in use make outrageous claims leading to the opportunity for his group at UNC to test most of them. Participants will benefit from hearing what constitutes good 3D superimposition and how small errors in superimpositions or the selecting reference planes can result in large measurement errors.

Statistics that make a Difference – Dr. Nik Pandis
Good quality randomized clinical trials and systematic reviews are highly desirable as sources of evidence. It is apparent that the number of randomized trials and systematic reviews has increased dramatically over the last 20 years, however, a lot remains to be done. This presentation will highlight common and recurring errors at the design, conduct and reporting stages of clinical trials and systematic reviews. The concept of research waste resulting from conducting studies of poor methodology as well as poor reporting will be introduced. Finally, initiatives for improving trial conduct and reporting within the specialty will be highlighted.

Changing Modes of Decision-making – Dr. David Turpin
The treatment planning skills of these selected speakers will focus on combining 3-D solutions to solve a myriad of orthodontic problems. These include how to get the most out of skeletal anchorage, the use of 3-D printing and Invisalign, orthognathic surgery to resolve maxillary width and even sleep apnea problems. For clinicians as well as orthodontic educators, it is believed that more clearly designed clinical research studies will lead to improved acceptance rates for studies submitted to the world’s leading journals.

Common Mistakes made by Authors when Preparing Manuscripts – Dr. Jorge Faber
Framing relevant questions is the key to successful clinical research. Additionally, authors need to enhance the phrasing of the article itself. A poorly presented study tends to cause the reader to question whether the authors themselves are not wary when writing the manuscript. During this presentation I will cover the most common mistakes most authors make when they prepare and submit their manuscripts for publication.

The National Adult Anterior Openbite Study- Dr. Greg Huang
Open bites are some of the most challenging malocclusions to correct, and stability after correction is never certain. Dr. Huang will describe an ongoing study of more than 300 adult open bite patients treated by more than 90 practitioners from across the US. What techniques are commonly recommended by orthodontists, and do patients accept these recommendations? Which techniques result in the highest rates of successful treatment, and do patient characteristics affect success rates? How satisfied are patients with the results of treatment, and what factors influence their satisfaction?

Another Approach to Bone Anchorage – MARPE/SARPE – Dr. Tung Nguyen
At UNC we are now analyzing two samples of consecutively treated cases with three CBCT time points. For the SARPE patients, 64% had some form of dehiscence before treatment. After treatment, 95% had dehiscence while in the retention phase, it went up to 100%. With MARPE I was expecting better numbers, but initially 56% had dehiscence and that increased to 88% and remained about the same during retention. It appears that neither surgical cuts nor mini-screws really helped to decrease the incidence of dehiscence.

Mini-workshop: Designed to critically appraise a published trial – Dr. Nik Pandis
Randomized clinical trials (RCT) are considered the gold standard to assess the efficacy and safety of an intervention and RCTs form the backbone of high quality systematic reviews. This presentation will use an interactive approach and guide the participants in how to critically appraise a published clinical trial. Instead of initially presenting the fundamentals of a clinical trial, the presentation will start and end with the appraisal of the selected publication. During the appraisal, the relevant concepts of clinical trial methodology will be explained and immediately applied to the example at hand. The published trial and the appraisal form will be sent to the participants at least a week in advance to allow time for preparation
