Orthodontics, Cleft & Orthognatic

Background of research

This collaborative, innovative and dynamic research group, aimed to produce good quality, high impact research on three main principal areas, namely orthodontics, cleft and orthognathic. Orthodontics is a specialty in dentistry that addresses the diagnosis, growth modification, prevention, and management of the dentofacial deformities and malocclusion including cleft and orthognathic.
