摘要
目的:牙体预备时损伤邻牙,冠修复后出现食物嵌塞时的应对措施。方法:选择临床确诊为因牙体预备时对邻牙造成损伤冠修复后出现食物嵌塞的病例121例,以邻接缝隙大小分为:a,牙线有阻力,但接触关系为面接触;b,牙线可轻松通过;c,邻接有<0.5mm间隙三组。A,b,c三组采用恢复邻牙形态后冠修复;记录术后1周与6月复查食物嵌塞情况。结果:治疗后1周嵌塞症状完全消失111例,占91.7%;明显好转10例,占8.3%。术后6月复诊:嵌塞症状完全消失115例,占95.0%;明显好转6例,占5.0%。结论多数食物嵌塞症通过树脂恢复邻牙邻面形态再进行冠修复的方法可以取得良好的效果。
Objective:To study the solutions to food impaction after coronal restoration which cause by the injury of adjacent tooth when preparing tooth in the posterior area.Methods:Select 121 clinically diagnosed cases of food impaction after coronal restoration which cause by the injury of adjacent tooth when preparing tooth in the posterior area.Divide them into four groups according to the interproximal clearance.Namely group a:there exists resistance when using dental floss and the contact relation is surface-to-surface contact:group b:the dental floss can easily pass:group c:the interproximal clearance is less than 0.5mm:Group a,b,c restored the crowns after repairing the morphology of adjacent teeth.Record the situation of food impaction 1 week later and six months later after operation.Results:1 week later after operation,the syndrome of food impaction absolutely disappeared in 111 cases which accounted for 91.7%.The other 10 cases which occupied 8.3%improved markedly.Six months later after operation,the syndrome of food impaction absolutely disappeared in 115 cases which accounted for95.0%.And 6 cases which occupied 5.0%improved markedly.Conclusion:Most of the food impaction can achieve good effects by repair the morphology of adjacent tooth with resin.
