种植义齿邻接触丧失的研究现状

Interproximal open contacts between implant restorations and adjacent teeth

随着种植义齿越来越多地应用于治疗牙列缺损,许多研究者发现种植戴冠后种植义齿与相邻天然牙之间逐渐发生了邻接触变松或丧失,邻接触丧失导致的食物嵌塞是种植修复的主要并发症之一。国内外学者对种植义齿邻接触丧失的发生率、发生原因以及治疗措施进行了深入研究,本文对相关研究结果进行总结。

Implant-supported protheses are considered a predictable option for dentition defects.Many researchers have observed the loss of proximal contact between implant-supported protheses and adjacent natural tooth.Food impaction,which mainly caused by proximal contact loss,is one of the main complications of dental implants.This article reviews research advancements on the prevalence,contributing factors and treatments of this complication.
