目的：牙齒自體移植是個適合用來修復缺牙的一種手術方式，其中包括了手術相關及牙齒本身治療的研究，自20世紀就開始不少學者討論將牙齒移動到他處去取代空缺處，其中展現出的高成功率和存活率讓這類型的研究持續發展著。其中近代討論到的3D模型技術輔助可以有效地降低捐贈牙的體外時間，進一步的降低以往對於牙周韌帶的影響，也同時有更多的研究探討手術中去進行其他的操作，進一步讓完整牙根發育之牙齒可以有更多的機會移植。本研究的目的是針對2015年至2023年期間共40位患者共45顆牙齒進行完整發育牙根之牙齒自體移植分析，評估成功率及存活率，及其根管治療介入的方式種類及影響。
材料與方法：經過檢查2015年至2023年在國立成功大學醫學院附設醫院口腔醫學部(臺灣)接受移植的患者的醫療記錄，放射線影像則由三位專科醫師判讀。僅考慮完整發育牙根之牙齒移植的患者，統計分析評估存活率和成功率，及根管治療介入之影響及其他影響可能變量。
結果：手術平均年齡為35.1 ± 12.5歲，平均追蹤時間為11.7 ± 9.9個月，最近一次回診成功率為64.1%，存活率為89.7%。根管治療介入沒有顯著差異影響。
結論：牙齒自體移植之存活率跟以往研究類似，而成功率屬於範圍內但是偏低，有可能是採用了較嚴格的方式判引起。但就存活率來看，照流程操作的牙齒自體移植是個適合彌補缺牙區的方式，也同時目前的證據顯示根管治療介入不會有影響。

Objective: Tooth autotransplantation is a surgical method for the rehabilitation of missing teeth. It was reported to have high success and survival rates. Recent research has shown that using 3D modeling technologies effectively reduces the extracorporeal duration of donor teeth, thereby decreasing the damage to the periodontal ligament. Additionally, there has been increased research into other treatment interventions during surgical time. This study aims to analyze tooth autotransplantation performed on 40 patients involving 45 teeth from 2015 to 2023, assessing the success and survival rates, along with the types and effects of endodontic interventions.
Materials and methods: Medical records of patients with tooth transplantation from 2015 to 2023 were reviewed. Radiographic images were examined by three specialists. Only patients with fully developed teeth were included. Statistical analyses were conducted to evaluate survival rates and success rates, and the impacts of endodontic interventions and others.
Results: The mean age of the patients at the time of surgery was 35.1 ± 12.5 years, with a mean follow-up duration of 11.7 ± 9.9 months. The success rate at the latest follow-up was 64.1%, while the survival rate was 89.7%. There was no significant difference from endodontic interventions.
Conclusions: Though the small sample size and short follow period, the survival and success rates are similar to those reported in previous research, confirming the effectiveness of tooth autotransplantation with complete root formation when strict protocols and appropriate indications are followed. Moreover, this study indicates that endodontic treatments do not interfere with the transplantation outcomes.
