The aim of this study was to determine the long-term outcome of autotransplanted maxillary canines and to investigate the influencing parameters. Seventy-one patients (84 transplanted canines) volunteered to participate in this study. The mean follow-up time was 21 years. In case of tooth survival and when patients were found willing for recall, teeth were investigated clinically and radiographically. Transplanted teeth were compared to the contralateral canine and scored with an aesthetic and radiographic index. The survival rate was 67.9%, considering that 27 transplanted teeth were lost before examination. The mean survival time was 15.8 years. Maxillary canine autotransplantation may have a successful outcome up to 21 years after transplantation requiring minimal patient compliance and low financial costs. The survival rate can be considered favorable realizing that autotransplantation is a treatment option in a selected group of cases.
本研究的目的是确定自体移植上颌尖牙的长期预后，并调查影响因素。71名患者（84颗移植尖牙）自愿参与本研究。平均随访时间为21年。对于牙齿存活且患者愿意复诊的情况，对牙齿进行临床和影像学检查。将移植牙与对侧尖牙进行比较，并用美学和影像学指数评分。考虑到27颗移植牙在检查前已丢失，存活率为67.9%。平均存活时间为15.8年。上颌尖牙自体移植在移植后长达21年可能会有成功的结果，所需患者依从性极低且费用低廉。鉴于自体移植是特定病例组的一种治疗选择，可以认为其存活率是令人满意的。
