Abstract

Implant restoration is currently the most mainstream method for repairing missing teeth. With the increasing number of plantings, various planting complications begin to be paid attention to. Among them, there are many reports of disability phenomena such as loose and broken abutment screws and broken top screws, which cause the implant to fail or fail to function. In recent years, with the development of computer-aided software and its application in the field of oral treatment, digital guide plates based on 3D printing of oral CBCT scanning data are widely used in oral implants. Therefore, we explore the application prospect of post-core crown restoration after removing broken screws from the implant abutment with a digital guide plate. We reported a case of upper right first molar implant abutment screws broken, which were removed by a digital guide plate and customized turning bur. The resin-matrix ceramics crown post core was prepared, and then the occlusal force was tested by the T-ScanIII system. It provides a reference for the application of digital guide plates in special cases such as broken screws of implant abutment.

数字导板移除种植体基牙上的断裂螺钉：一例报告和文献复习。

种植体修复是目前修复缺失牙齿最主流的方法。随着种植数量的增加，各种种植并发症开始引起人们的关注。其中，有许多关于残疾现象的报道，如基牙螺钉松动、断裂、顶部螺钉断裂，导致植入物失效或无法发挥作用。近年来，随着计算机辅助软件的发展及其在口腔治疗领域的应用，基于口腔CBCT扫描数据3D打印的数字导板在口腔植入物中得到了广泛应用。因此，我们探索了用数字导板去除种植体基牙断裂螺钉后核冠修复的应用前景。我们报告了一例右上第一磨牙种植体基牙螺钉断裂的病例，这些螺钉通过数字导板和定制的旋转钻移除。制备了树脂基陶瓷冠柱芯，并用T-ScanIII系统对其咬合力进行了测试。为数字导板在种植体基牙螺钉断裂等特殊情况下的应用提供参考。
