摘　　要：目的:调查种植固定义齿与天然邻牙间食物嵌塞的患病率,分析其发病原因,为种植固定义齿修复后食物嵌塞的防治提供参考。方法:选择2014年6月至2016年6月于我院接受种植固定义齿修复的患者300名男性150人,女性150人;年龄60~71岁,平均64岁;共620枚植体,376个种植修复体,600个邻接区进入调查。采取问卷调查结合口腔检查的方法,对其性别、牙尖斜度、口腔卫生习惯、种植方案、修复方案等进行调查,并将数据进行统计分析。结果:食物嵌塞患病率为32.0%,单因素分析显示邻接区位置、种植位置、骨增量手术、邻接强度、邻接区到牙槽嵴顶距离、种植区角化龈宽度、种植体与邻牙水平距离和台阶有统计学差异(P<0.05),多因素分析显示邻接区位置、邻接强度、邻接区到牙槽嵴顶距离、种植区角化龈宽度、种植体与邻牙水平距离和台阶为种植固定义齿食物嵌塞的影响因素。结论:种植固定义齿修复后食物嵌塞患病率较高,良好的邻接及软硬组织健康状况可以预防食物嵌塞。Objective:To investigate the prevalence of food impaction between implanted-fixed prostheses and natural adjacent teeth,analyze the causes of the disease,so as to provide reference for the prevention and treatment of food impaction after implanted-fixed prostheses repair.Methods:From June 2014 to June 2016,300 patients(150 males and 150 females)who received implant fixed denture prostheses in our hospital were selected.The average age was 64;Range,60-71 years old,a total of 620 implants,376 implant prostheses and 600 adjacent areas were investigated.Questionnaire survey combined with oral examination was used to investigate the gender,inclination of cusp,oral hygiene habits,planting plan and restoration plan,and the data were statistically analyzed.Results:The prevalence rate of food impaction was 32.0%,Univariate analysis showed that there were statistically significant differences in location of adjacent area,Implant location,guided bone regeneration,adjacency intensity,distance from adjacent area to alveolar crest,the width of keratinized gingival,horizontal distance between implant and adjacent tooth,and the step(P<0.05).Multi-factor analysis showed that location of adjacent area,intensity of proximal contact,distance from adjacent area to alveolar crest,the width of keratinized gingival,horizontal distance between implant and adjacent tooth,and the step were the influencing factors.Conclusion:The prevalence of food impaction between implanted-fixed prostheses and natural teeth is higher,Good abutment and healthy soft with hard tissue can prevent it.
