Abutment screw loosening has been reported to be the most common prosthetic complications occurring in screw retained as well as cement retained implant restorations. Different methods to treat this issue have been reported in the literature so far; however these have their own short-comings. Retrievability of an implant restoration intact becomes a clinical challenge when the restoration is cement retained especially with an angulated abutment. This technique is aimed at accurately determining the position of the abutment screw in 3 dimensional relationships using a vacuum formed clear stent. This technique can be used as a viable protocol for management of screw loosening in cement retained implant restorations.
据报道，基台螺丝松动是螺丝固位和粘结固位种植体修复中最常见的修复并发症。迄今为止，文献中已报道了治疗该问题的不同方法；然而，这些方法都有其自身的缺点。当修复体为粘结固位时，尤其是使用角度基台时，完整取出种植体修复体成为一项临床挑战。该技术旨在使用真空成型透明支架精确确定基台螺丝在三维关系中的位置。该技术可作为粘结固位种植体修复中螺丝松动管理的可行方案。
