种植固定修复后邻接关系不良的研究进展

Research progress on proximal contact loss between implant-supported fixed prostheses and adjacent natural teeth

随着种植修复技术的普及,种植修复后并发症的处理也越来越受到临床医生的关注。以前的研究热点主要在种植生物并发症和机械并发症上,但邻接关系不良也是种植固定修复常见的并发症,是导致食物嵌塞、影响咀嚼功能的主要原因,严重降低患者的义齿使用舒适度。近年来,多篇文献报道了邻接关系不良的高发生率,种植修复体邻接关系不良导致的食物嵌塞问题,已成为新的研究热点。本文就种植固定修复后出现邻接关系不良的原因、临床特点及对策进行综述。

With the popularization of implant restoration technology, the treatment of complications is increasingly becoming a concern of clinicians. Previous studies mainly involved implant biological and mechanical complications. However, approximal contact loss is also a common complication of implant fixed restoration, which is the main cause of food impaction and affects chewing function, thereby significantly decreasing the patient’s denture comfort. Many studies have reported high approximal contact loss incidence, and the problem of food impaction caused by approximal contact loss of implant restoration has become a new topic receiving considerable research attention. This article reviews the causes, clinical features, and countermeasures of approximal contact loss after implant fixation.
