In this report, treatment and long term effects of mandibular symphyseal distraction osteogenesis (MSDO) on dentofacial structures are presented. The distraction device used in the present case was a custom made tooth- and bone-borne distractor. Post-treatment records revealed elimination of mandibular anterior crowding, no temporomandibular joint (TMJ) disorder, no periodontal pathology and no root resorption. Follow-up records taken 6 years after the completion of the treatment indicated no mandibular anterior crowding or TMJ disorder. Treatment and long term results of this case suggest that mandibular widening with distraction osteogenesis is an efficient, safe and stable treatment modality for patients presenting transverse mandibular deficiency and/or mandibular anterior dental crowding. However, large sample studies are required to draw substantial conclusions about the long term effects of the MSDO on dentofacial structures.
本报告介绍了下颌正中联合牵张成骨（MSDO）治疗和长期效果对牙颌面结构的影响。本病例中使用的牵开器是一种定制的牙骨内牵开器。治疗后的记录显示，下颌前牙拥挤得到消除，颞下颌关节（TMJ）无紊乱，牙周无病变，无牙根吸收。治疗完成 6 年后的随访记录显示，下颌前牙拥挤或 TMJ 紊乱均无发生。本病例的治疗和长期结果表明，下颌骨扩弓牵张成骨是治疗横向下颌骨发育不足和/或下颌前牙拥挤患者的一种有效、安全、稳定的治疗方法。然而，需要进行大规模的研究才能对 MSDO 对牙颌面结构的长期影响得出实质性结论。
