: The purpose of this study is to observe the usefulness of autogenous tooth transplantation by examining the cumulative survival rate according to the period of auto-transplanted teeth as pre-implant treatment. : This study was conducted on 111 patients who visited Kyungpook National University Dental Hospital and underwent autogenous tooth transplantation between November 2008 and January 2021 (about 13 years). The cumulative survival rate of autogenous tooth transplantation according to the causes of extraction of the recipient tooth (caries, periapical lesion, crack, crown fracture, periodontitis) and condition of opposing teeth (natural teeth vs. fixed prosthesis). The cumulative survival rate of autogenous tooth transplantation according to the age (under 30 vs. over 30) was also investigated and it was examined whether there were any differences in each factor. : The average follow-up period was 12 months, followed by a maximum of 162 months. The 24-month cumulative survival rate of all auto-transplanted teeth was 91.7%, 83.1% at 60 months and the 162-month cumulative survival rate was 30.1%. There were no statistical differences between the causes of extraction of the recipient's teeth, differences in the condition of the opposing teeth, and differences under and over the age of 30. : The survival rate of autogenous tooth transplantation appears to be influenced by the conditions of the donor tooth rather than the conditions of the recipient tooth. Although autogenous tooth transplantation cannot completely replace implant treatment, it is meaningful in that it can slightly delay or at least earn the time until implant placement is possible.
: 本研究旨在通过检查自体牙移植的累积存活率，观察自体牙移植作为种植前治疗的效果。 : 本研究共纳入 111 例患者，他们于 2008 年 11 月至 2021 年 1 月（约 13 年）期间在庆北国立大学牙医院接受了自体牙移植。根据受植牙（龋齿、根尖周病变、裂纹、冠折、牙周病）和对颌牙（天然牙与固定义齿）的拔除原因以及情况，观察自体牙移植的累积存活率。还调查了自体牙移植的年龄（<30 岁与>30 岁）的累积存活率，并检查了各因素之间是否存在差异。 : 平均随访时间为 12 个月，最长随访时间为 162 个月。所有自体移植牙的 24 个月累积存活率为 91.7%，60 个月的存活率为 83.1%，162 个月的累积存活率为 30.1%。受植牙拔除原因、对颌牙状况、年龄<30 岁与>30 岁之间的差异无统计学意义。 : 自体牙移植的存活率似乎受供体牙的条件影响，而不是受受体牙的条件影响。虽然自体牙移植不能完全替代种植治疗，但它具有一定的意义，因为它可以稍微延迟或至少获得直到可以进行种植体放置的时间。
