An innovative abutment system has recently been developed to address the well-known limitations of screw- and cement-retained implant restorations. This abutment system offers retrievability by replacing the cement layer with a precision-engineered nickel-titanium sleeve that switches between shapes that lock and unlock the prosthesis. The avoidance of cement precludes cement-related periimplant complications, while the elimination of occlusal screw access holes may enable predictable control over occlusion and improve the structural integrity of the prosthesis. By eliminating the need for cement clean up, occlusal access closure, and occlusal adjustments after insertion, the dentist is afforded more time to attend to the patient's general needs. This paper describes the design rationale for and clinical treatment using this novel abutment system.
最近开发了一种创新的基台系统，以解决螺钉固位和粘结固位种植体修复众所周知的局限性。该基台系统通过用精密设计的镍钛套筒取代粘结层来实现可取出性，该套筒在锁定和解锁假体的形状之间切换。避免使用粘结剂可防止与粘结剂相关的种植体周围并发症，而消除咬合螺钉接入孔可实现对咬合的可预测控制并提高假体的结构完整性。通过消除植入后清理粘结剂、封闭咬合接入孔和进行咬合调整的需要，牙医有更多时间关注患者的一般需求。本文描述了这种新型基台系统的设计原理和临床治疗方法。
