Apicoectomy is an endodontic surgical intervention that requires high precision. The computer-assisted static guided approach has proven to increase the precision of dental implantation in a significant manner. The authors sought to transfer this precision to root-end resection with the use of custom designed trephine burs manufactured specifically for use in targeted endodontic microsurgery.
A set of custom bone trephines were designed and manufactured, then their digital models were integrated into an already existing implant surgical planning software, in cooperation with the software developer. Apicoectomy was performed in an actual case with the help of the new system.
It has become possible to plan root end removal in the virtual space and to manufacture 3D printed static surgical guides to help the execution of the surgery. A patient with persistent periapical lesion was successfully treated without complication. The 6-month follow-up found uneventful healing.
The presented system is a step toward a standardized digital system and workflow dedicated to guided endodontic surgery.
根尖切除术是一种需要高精度的牙髓外科手术。计算机辅助静态引导方法已被证明能显著提高牙种植的精度。作者试图通过使用专门为靶向牙髓显微手术设计的定制环钻，将这种精度应用于根尖切除。
设计并制造了一套定制骨环钻，然后与软件开发人员合作，将其数字模型集成到现有的种植手术规划软件中。在新系统的帮助下，对一个实际病例进行了根尖切除术。
已能够在虚拟空间中规划根尖切除，并制造3D打印的静态手术导板以协助手术执行。一名患有持续性根尖周病变的患者成功接受治疗，无并发症发生。6个月的随访发现愈合顺利。
所介绍的系统是迈向致力于引导牙髓手术的标准化数字系统和工作流程的一步。
