【摘要】：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(P0.05),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。
[Abstract]:The proximal and middle contact surface of the fixed restored molar was taken as the research object. The experimental group made the tightness of the adjacent surface slightly tighter than that of the healthy side, while the control group routinely made the prosthesis. The prosthesis was followed up for 1 month and 12 months after bonding respectively. 1 month follow-up data showed that there was no significant difference in the incidence of food impaction between the experimental group and the control group, and 6 and 12 months follow-up data showed that the experimental group and the control group had no significant difference in the incidence of food impaction. There was significant difference in the incidence of impingement (. P0.05). The results showed that the tightness of the adjacent surface in fixed repair could reduce the incidence of food impaction.

【正文快照】： 2014-11-13接收在咀嚼过程中,食物被咬牙合压力楔入相邻两牙的牙间隙内,称为食物嵌塞。临床上进行全冠修复时,常常会发生修复后食物嵌塞。全晓明等[1]报道食物嵌塞占固定义齿修复失败病例的17.5%。固定义齿修复后发生食物嵌塞的原因很多,其中最主要的原因是修复体邻接关系不良
