The aim of the present study was to evaluate the factors affecting the prognosis of the autotransplantation of teeth with complete root formation.
A total of 259 transplanted teeth were studied. The significance of each of the prognostic factors was examined in 2 ways, first in a univariate analysis and then in a multivariate analysis. The comprehensive risk combining these factors that remained after multivariate analysis was calculated.
Among 259 transplanted teeth, 27 (10.4%) were judged as unsuccessful cases. In the multivariate analysis, history of root canal treatment of donor tooth, multirooted, maxillary tooth as a donor, and duration of tooth absence at recipient site remained significantly associated with unsuccessful transplantation. Multifarious combination of the significant prognostic factors can decrease the comprehensive risk.
Minimizing the comprehensive risk by combining significant prognostic factors improved the prognosis of autotransplantation of teeth with complete root formation.
本研究旨在评估影响完全形成根的自体移植牙预后的因素。
共研究了 259 颗移植牙。通过单因素分析和多因素分析两种方法，分别检查了每个预后因素的意义。计算了多因素分析后剩余的综合风险因素。
在 259 颗移植牙中，27 颗（10.4%）被判断为不成功病例。多因素分析显示，供牙的根管治疗史、多根、上颌牙和受植部位牙缺失时间与移植失败显著相关。显著预后因素的多种组合可以降低综合风险。
通过组合显著的预后因素，降低综合风险，可改善完全形成根的自体移植牙的预后。
