AIM
To present the 14 year follow-up of a case in which an avulsed permanent maxillary central incisor was replaced by autotransplantation of a mandibular premolar.
SUMMARY
A mandibular premolar (Moorrees' stage 3) was transplanted into the space left by an avulsed permanent maxillary central incisor after a delay of 3 months. Recall examination 14 years after transplantation revealed a normal periodontal architecture with absence of infection, ankylosis or progressive resorption. The transplantation of a premolar is seen as a promising method to replace a lost permanent tooth and to restore aesthetics and function.
KEY LEARNING POINTS
- Autotransplantation is a viable option for the treatment of a missing tooth or for replacement of avulsed and traumatized tooth when a donor tooth is available. * Autotransplantation is a therapeutic option for the substitution of missing anterior teeth in young patients who also need orthodontic treatment.
目的
介绍一例上颌恒中切牙脱位后自体移植下颌前磨牙,14 年随访的结果。
摘要
脱位 3 个月后,将一颗下颌前磨牙(Moorrees 分期 3 期)移植到上颌恒中切牙缺失的位置。移植后 14 年的复查显示,牙周结构正常,无感染、骨粘连或进行性吸收。前磨牙的自体移植被视为一种有前途的方法,可用于替代缺失的恒牙,并恢复美观和功能。
主要知识点
自体移植是治疗缺失牙或当有供体牙时,用于替代脱位和创伤牙的可行选择。
自体移植是年轻患者缺失前牙且需要正畸治疗时的一种治疗选择。
