"Professor Hwang Chung-Ju’s Research Team Honored by theCollege ofdiplomates of the American board of orthodontics for best Case report of the year"

The College of Diplomates of the American Board of Orthodontics (CDABO) selected the Case Report by Prof. Hwang Chung-Ju and Dr Choi Sung-Hwan, Dept of Orthodontics College of Dentistry Yonsei University, “Orthognathic treatment with autotransplantation of a third molar”, as the 2013 CDABO Case Report of the Year Award.

This Award originated in the year 2000 by the College of Diplomates of the American Board of Orthodontics for the purpose of placing greater emphasis on improving the finishing of orthodontic treatment. The College also wanted to encourage more clinicians to publish their case reports in the American Journal of Orthodontics & Dentofacial Orthopedics (AJO-DO).

This article was published in the november 2013 issue of AJO-DO. These authors demonstrated successful orthognathic treatment that included autotransplantation of a maxillary left third molar in a patient with a missing mandibular right first molar, mandibular protrusion, and facial asymmetry. A 20-year-old woman had mandibular protrusion and facial asymmetry. Five years previously, her mandibular right first molar had been extracted because of dental caries. After preoperative orthodontic treatment with extraction of the maxillary first premolars and using temporary skeletal anchorage devices, we performed a LeFort I procedure and a bilateral intraoral vertical ramus osteotomy to correct the patient’s mandibular protrusion and facial asymmetry. During the postoperative orthodontic treatment, the maxillary left third molar was autotransplanted into the mandibular right first molar site. As a result of these therapeutic treatments with autotransplantion of a third molar, the patient’s facial appearance was improved, and an implant was unnecessary. The autotransplanted tooth effectively supported the adjacent teeth and maintained her chewing ability.

Prof. Hwang Chung-Ju and Dr Choi Sung-Hwan were presented with a framed certificate of the Award during the Annual CDABO Luncheon on Saturday, April 26th, 2014, at the Annual Session of the American Association of Orthodontists in new Orleans, La.
