邻接紧密型食物嵌塞的发病机制与诊疗技术研究进展

Etiology and clinical technology of the food impaction with tight proximal contacts

邻接紧密型食物嵌塞,也称运动型食物嵌塞或无解剖结构破坏型食物嵌塞,是指咬合运动过程中相邻牙齿的邻面接触区出现短暂分离而造成的食物嵌塞,其患病率较高,是一种顽固性食物嵌塞。目前,学术界认可的邻接紧密型食物嵌塞的发病机制主要有两种:①咬合瞬间远中牙齿的可逆性近中移位不足以及牙齿生理性不可逆性近中移位与邻牙不同步;②食物溢出途径缺失,此机制目前尚缺乏定量研究附证。邻接紧密型食物嵌塞的首选治疗方式为调,但包含调磨位置、面积、体积等内容的个性化及定量化治疗标准以及调磨结果的定量预测与评估方法,目前尚不明确。本文针对邻接紧密型食物嵌塞的发病机制和具体治疗方式现状进行综述,以期为科学研究和临床应用提供参考。

Food impaction with tight proximal contacts, also known as kinetic food impaction and food impaction without anatomical structure destruction, is mainly caused by a transient separation in contacts area during mastication. It′s an intractable food impaction with high morbidity and low cure rate. There are two kinds of pathogenesis accepted: the shifting of anterior teeth incongruous with adjacent teeth or lack of anterior shifting;lack of food escape grooves. The preferred treatment is occlusal adjustment, but it′s difficult to determine the area and extent of selective grinding, to quantify the occlusal adjustment, or to predict the prognosis. This review summarized the pathogenesis and treatment modality for kinetic food impaction in order to provide evidence for future researches and clinical application.
