Dr. Bryon Viechnicki Wins Pennsylvania Orthodontic Award for Research in Jaw Growth

The Pennsylvania Association of Orthodontists has awarded Bethlehem orthodontist, Dr. Bryon Viechnicki, the David C. Hamilton Orthodontic Research Award.  The research award helps support continuing education and research at Pennsylvania’s orthodontic programs.

As seen in:

Dr. Viechnicki’s research demonstrates the uniqueness of lower jaw growth in adolescents using 3D technology. The research was conducted at the Department of Orthodontics at Temple University, Philadelphia, PA, where Dr. Viechnicki is a Clinical Adjunct Assistant Professor of Orthodontics.  His collaborators included Dr. Orhan Tuncay (Chairman, Department of Orthodontics), Dr. Jared Gianquinto orthodontist, Bakersfield, CA), and Dr. Jinwu Chen (Associate Professor, Fourth Military Medical University,China).

The award is named in honor of Dr. David C. Hamilton, New Castle, PA.  Few orthodontists in our state have contributed more to our specialty than Dr. Hamilton. He was one of the original founders of the Pennsylvania Association of Orthodontists, has served as President of the PAO as well as the American Association of Orthodontists, and lectured around the world to orthodontic groups and graduate students.

Dr. Viechnicki will present the findings of this new 3D research at the International Association of Dental Research General Session in Iguaçu Falls, Brazil on Saturday, June 23, 2012 at 9:00 a.m.

Research Synopsis

Three-dimensional analysis of mandibular growth aids the clinician to plan treatment in harmony with the individual growth of the patient. Current 3D visualizations of growth and development remain reminiscent of landmark-based cephalometric analyses used in 2D studies. Unfortunately, landmark-based cephalometrics belie the underlying mechanisms of surface apposition and resorption by which the mandible grows and develops. The objective of this study was to identify the 3D topographical changes of the mandible that occur during growth and development of adolescent orthodontic patients by developing a procedure for volumetric regional superimposition of serial CBCTs. Visualization of changes in mandibular surfaces offers a biologically meaningful assessment of growth and development and the effects of orthodontic treatment. The findings of this study corroborate theories of bone remodeling reported in histological, implant-based, and landmark studies of mandibular growth.
