The screw-joint stability of single-tooth implant-supported restorations has been shown to be significantly improved with an abutment system (CeraOne) that uses a gold-alloy screw tightened at a prescribed amount of torque. The abutment system requires the cementation of the restoration to the abutment. This negates the possibility of accessing the abutment screw when the removal of the restoration is desired. This article described two alternative restorative techniques to maintain accessibility to the screw joint.
单颗牙种植支持式修复体的螺钉连接稳定性已被证明，使用一种在规定扭矩下拧紧的金合金螺钉的基台系统（CeraOne）可显著提高。该基台系统要求将修复体粘结到基台上。当需要取下修复体时，这就排除了接触基台螺钉的可能性。本文介绍了两种替代修复技术，以保持对螺钉连接的可及性。
