Tooth autotransplantation (AT) involves the surgical relocation of a tooth from 1 site in the mouth to another site within the same patient. This approach is a good option in a growing patient when dental implant placements or fixed bridges are not suitable and when preserving natural teeth is a priority. Tooth AT is a complex procedure that requires specialized skills from a multidisciplinary team with careful patient and tooth selection and treatment planning.
The authors provided a review of the state of knowledge and research on tooth AT and presented a case scenario and barriers to adoption, with a focus on the United States.
Success rates for tooth AT can vary depending on several factors, including the patient's overall health, specific tooth involved, skill of the dental surgeon, and postoperative care provided. Long-term outcomes of autotransplanted teeth have been cited in the literature with impressive longitudinal follow-up spanning up to 26 years. Results of several systematic reviews showed survival rates from 75% through 98%.
Adoption of tooth AT has grown over the years, owing to advancements in dental techniques, improved patient outcomes, and increased awareness among both dentists and patients. Increasing awareness and availability of tooth AT to replace missing teeth can provide a natural and functional alternative to traditional prosthetic options. Tooth AT helps preserve the alveolar bone in growing patients and can offer excellent esthetic and functional outcomes.
牙自体移植（AT）涉及将牙齿从口腔中的一个位置手术转移到同一患者体内的另一个位置。在需要种植体植入或固定桥不适合且保护天然牙齿是首要任务的生长患者中，这种方法是一个不错的选择。牙 AT 是一项复杂的手术，需要由多学科团队具备专业技能，精心选择患者和牙齿，并进行治疗规划。
作者对牙 AT 的知识和研究状况进行了综述，并提出了一个案例场景和采用的障碍，重点是在美国。
牙 AT 的成功率可能因多种因素而异，包括患者的整体健康状况、具体涉及的牙齿、牙医的技能以及提供的术后护理。文献中引用了自体移植牙的长期结果，最长纵向随访时间长达 26 年。几项系统评价的结果显示，存活率从 75%到 98%不等。
由于牙科技术的进步、患者结果的改善以及牙医和患者对其的认识提高，牙 AT 的应用多年来有所增加。增加对牙 AT 的认识和可用性，以替代缺失的牙齿，可以为传统修复选择提供自然和功能替代方案。牙 AT 有助于在生长患者中保存牙槽骨，并能提供出色的美观和功能结果。
