以固定修复的磨牙近中接触面为研究对象。实验组制作比健侧稍紧的邻面松紧度，对照组常规制作试戴修复体。分别于粘固后1、6、12个月随访，比较两组食物嵌塞的发病率。1个月的随访资料表明实验组与对照组食物嵌塞发病率的差异无统计学意义。6个月和12个月的随访资料表明实验组与对照组食物嵌塞发病率的差异有统计学意义(P<0．05)，表明固定修复时制作稍紧的邻面松紧度能降低食物嵌塞的发病率。

Using the fixed restoration of the molar as the research object. The adjacency relationship was made a little tight. Conventional method was used to adjust the fixed denture in control group. Each group were given clini-cal follow-up after 1,6,and 12 months, respectively, the incidence of the food impaction in the two groups could be compared. The follow-up data of 1 month showed that the difference between experimental group and control group in the incidence of food impaction had no statistical significance and the follow-up data of 6 months and 12 months showed that the difference of experimental group and control group in the incidence of food impaction had some sta-tistical significance(P<0. 05). The method in this paper could reduce the incidence of food impaction after fixed restoration.
