Computer-guided flapless surgery for implant placement using stereolithographic templates is gaining popularity. The advantages of this surgical protocol are its minimally invasive nature, accuracy of implant placement, predictability, and reduced time required for definitive rehabilitation. One of the disadvantages, however, pertains to complete arch implant rehabilitation. An existing protocol for complete arch flapless computer-guided implant surgery necessitates the patient to be rendered completely edentulous and to wear a removable complete denture for varying periods of time. This may be objectionable to the patient. This article illustrates a technique which uses a modified radiographic template to overcome this limitation. The patient may have a tooth-supported or implant-supported fixed interim prosthesis during the entire rehabilitation process.
使用立体光刻模板进行计算机引导的无瓣种植体植入手术正越来越受欢迎。该手术方案的优点包括微创性、种植体植入的准确性、可预测性以及确定性修复所需时间的减少。然而，其缺点之一与全牙弓种植体修复有关。现有的全牙弓无瓣计算机引导种植手术方案要求患者完全无牙，并在不同时间段佩戴可摘全口义齿。这可能会引起患者反感。本文阐述了一种使用改良放射模板来克服这一局限性的技术。在整个修复过程中，患者可以佩戴牙支持或种植体支持的固定临时修复体。
