序列调法治疗运动型食物嵌塞的临床观察

Clinical observation of sequential occlusal adjustment for kinetic food impaction

目的探讨治疗运动型食物嵌塞的调方法及效果。方法选择邻面接触关系正常的食物嵌塞患者36例为研究对象,分析其咬合面形态及咬合关系,采用序列调方法进行治疗,并培养合理的饮食习惯。序列调法包括:调磨并消除对杵臼式牙尖、加深面发育沟、调磨嵌塞间隙远中牙齿的近中斜面。治疗后1周、2周和6个月复查食物嵌塞情况。结果术后1周,36例患者中有32例的食物嵌塞症状消失,4例症状改善;术后2周,所有患者食物嵌塞症状完全消失;术后半年后复查,并无1例发生食物嵌塞。结论序列调法是治疗某些运动型食物嵌塞的有效方法。

Objective To study the effectiveness of sequential occlusal adjustment for kinetic food impaction. Methods 36 patients who claiming food impaction with normal proximal contact were examined and analyzed about their occlusal relationship and configuration. Sequential oeclusal adjustment was made to reduce pestle-mortar-like cusp, to create food escaping groove and to decrease mesial surface of the distal tooth cusp. One week, two weeks and six months later, the patients were reexamined and their oral conditions were evaluated. Results An elimination of food impaction was claimed for 32 patients in one week appointment and all 36 patients in two-week appointment. Six months later, no patient reported food impaction. Conclusion The use of sequential occlusal adjustment results in an effective elimination of some kind of kinetic food impaction.
