DENTOFACIAL EFFECTS OF FIXED ORTHODONTIC TREATMENT WITH MANDIBULAR SYMPHYSEAL DISTRACTION OSTEOGENESIS AND RAPID MAXILLARY EXPANSION: A ONE-YEAR FOLLOW-UP CASE REPORT

Abstract

In this case report, the outcomes of a 17-year-old male patient who underwent fixed orthodontic treatment with rapid maxillary expansion (RME) and tooh-borne mandibular symphyseal distraction osteogenesis (MSDO) were presented. Orthodontic analysis was performed before and after treatment and after one-year follow-up. A significant expansion (+9.9 mm) was observed in mandibular canines after distraction and a 6.1 mm relapse occurred after fixed orthodontic treatment. In conclusion, both the dental and skeletal improvements obtained by the combined use of MSDO, RME, and fixed orthodontic treatment were preserved in the one-year follow-up period.
