Tooth autotransplantation is the technique of transplanting embedded, impacted or erupted teeth from one site into another in the same individual. Autotransplantation can provide a long-term, cost-effective and biological solution for adolescent patients with congenitally missing teeth or significantly compromised teeth when a suitable donor tooth is available. Successful autotransplantation of immature teeth can offer many advantages for a growing patient, including a normally functioning periodontium, proprioception and preservation of alveolar bone volume. Even in the event that an autotransplanted tooth does eventually fail, the bone and soft tissue conditions are likely to be conducive for subsequent implant treatment. Despite the significant physiological and cost-benefit advantages, tooth autotransplantation remains relatively underutilized, as the procedure is considered to be technique-sensitive. Although carefully considered individual case selection and surgical skill are the critical determinants for success, advances in three-dimensional computed tomography and rapid prototyping have the potential to simultaneously reduce the technique sensitivity and increase the predictability of the autotransplantation procedure. It is hoped that this case series will provide greater awareness and an appreciation of the tremendous value of autotransplantation for the management of patients with congenitally missing or significantly compromised posterior teeth.
牙自体移植是指将同一患者的埋伏牙、阻生牙或已萌出的牙移植到另一部位的技术。当有合适的供牙时，牙自体移植可为青少年缺失牙或严重受损牙患者提供一种长期、经济有效的生物学解决方案。对于生长中的患者，成功的未成熟牙自体移植具有许多优势，包括正常功能的牙周组织、本体感觉和牙槽骨量的保存。即使自体移植牙最终失败，骨和软组织条件也可能有利于后续的种植治疗。尽管牙自体移植具有显著的生理和成本效益优势，但由于该手术被认为具有技术敏感性，因此其应用相对较少。尽管仔细考虑个体病例选择和手术技能是成功的关键决定因素，但三维计算机断层扫描和快速原型制作技术的进步有可能同时降低技术敏感性并提高自体移植手术的可预测性。希望本病例系列能使更多人认识到自体移植在治疗先天性缺失或严重受损后牙方面的巨大价值。
