Autotransplantation is a treatment option with high reported survival rates to replace failing teeth in the anterior maxilla. This treatment requires a multidisciplinary approach from orthodontists, paediatric dentists, restorative dentists, and oral and maxillofacial surgeons to achieve successful outcomes. Success is dependent on many factors including stage of root development, handling of the periodontal ligament, extra-alveolar time and splinting. This case report presents the novel use of digitally designed and three-dimensional (3D) printed surgical templates to aid intraoperatively and reduce the extra-alveolar time. A preoperative cone-beam computed tomography scan allowed digital planning and construction of surgical templates that replicated the exact root dimensions of impacted maxillary canines. These templates were subsequently 3D printed in resin, sterilised and utilised intraoperatively to aid socket preparation before the surgical autotransplantation.
自体牙移植是一种据报道具有较高存活率的治疗方法,用于替换上颌前部的患牙。这种治疗需要正畸医生、儿童牙医、修复牙医以及口腔颌面外科医生采取多学科方法,以取得成功的治疗效果。成功取决于许多因素,包括牙根发育阶段、牙周膜的处理、牙槽外时间和固定。本病例报告展示了数字设计和三维(3D)打印手术模板的新用途,以辅助手术操作并减少牙槽外时间。术前锥形束计算机断层扫描允许进行数字规划并构建手术模板,这些模板复制了上颌阻生尖牙的确切牙根尺寸。随后将这些模板用树脂进行3D打印、消毒,并在手术自体牙移植前术中用于辅助牙槽窝制备。
