Dr. Zongyang Sun received his dental degree
in 1996 and an MS in Oral Anatomy and Physiology in 1999 from
West China University of Medical Sciences, Chengdu, China; he
then obtained an MSD in Orthodontics and a PhD in Oral Biology
in 2007 from University of Washington, Seattle. In 2008, he
joined the Ohio State University (OSU) College of Dentistry and
became an assistant professor in the Division of Orthodontics.
Dr. Sun’s general research interest is craniofacial skeletal
growth, repair and regeneration. His present research areas
- Mechanical, cellular and molecular
changes of alveolar bone following tooth extraction
- Craniofacial repair and regeneration using bone marrow stromal
- Characterization of mandibular periosteum
- Palatal expansion and circumaxillary suture strains
- Factors affecting the accuracy of alveolar bone measurements
from CBCT images.
His research is currently supported by NIH/NIDCR, American
Association of Orthodontists Foundation, Delta Dental and OSU
College of Dentistry. Dr. Sun is a board certified orthodontist
and he practices in the college faculty practice and in the
Children’s Hospital evening clinic. He is involved in didactic
and clinical teaching for dental students and orthodontic
residents. He also serves as an active reviewer for American
Journal of Orthodontics and Dentofacial Orthopedics and a
graduate faculty in the Division of Oral Biology at OSU. Email:
