The indications for autotransplantation of teeth in 45 patients have been analysed together with a follow-up of the success rate of surgery. Most of the transplants were mature teeth, 37 out of 51, with closed apex. The majority of transplantations were carried out in order to replace single tooth losses (40) but in 11 cases, the teeth were used as an abutment in prosthetic rehabilitation. In 14 cases, an impacted tooth was transplanted to its normal position. The follow-up ranged from 3 months up to 10 years. No progressive root resorption has been observed so far; only 6 cases with slight surface resorption. Clinical signs of anchylosis were noticed in 4 teeth and shallow bone defects in 6 patients. Small- or medium-sized periapical destructions were observed in 4 cases. Mature transplanted teeth were always subjected to endodontic therapy within a month; the immobilisation varied between 2-4 weeks, while trying to keep it as short as possible with maintained stability. The experiences so far achieved do encourage a more comprehensive use of the method to solve problems associated with oral rehabilitation, from both prosthodontic and orthodontic points of view.
对45例患者牙齿自体移植的适应证进行了分析,并对手术成功率进行了随访。大多数移植的是成熟牙齿,51颗中有37颗根尖已闭合。大多数移植手术是为了替换单颗缺失牙(40例),但在11例中,这些牙齿被用作修复重建中的基牙。在14例中,将阻生牙移植到正常位置。随访时间从3个月到10年不等。到目前为止,尚未观察到进行性牙根吸收;只有6例有轻微的表面吸收。4颗牙齿出现了骨性粘连的临床症状,6例患者有轻度骨缺损。4例观察到小或中型根尖周破坏。成熟的移植牙总是在一个月内接受根管治疗;固定时间在2至4周之间,同时尽量在保持稳定性的前提下使其时间尽可能短。到目前为止所取得的经验确实鼓励从修复和正畸的角度更全面地使用该方法来解决与口腔修复相关的问题。
