【摘要】 背景:总义齿再修复中,充分参考旧义齿的可利用信息是获得良好治疗效果的关键。目的:观察硅橡胶材料在总义齿再修复中的应用效果。方法:选择10例戴用旧义齿多年的无牙颌患者,利用技工用硅橡胶翻制旧义齿,同时结合硅橡胶印模材料在试排牙后进行口内印衬的方法重新制作总义齿。采用重复测量方差分析法研究两组新义齿使用前(旧义齿)及使用后2周、1个月、3个月、6个月咀嚼效率的变化。另选择10例患者按照常规方法重做义齿为对照。结果与结论:时间、处理因素(不同制作方法)的作用以及两者之间的交互作用对义齿咀嚼效率的影响差异有显著性意义(P<0.01)。与对照组同一时点比较,实验组新义齿使用2周、使用1个月的咀嚼效率较高(P<0.05)。实验组新义齿使用2周的咀嚼效率较使用前有明显改善(P<0.01),与使用后1个月比较差异无显著性意义(P>0.05)。结果提示在总义齿再修复中,利用硅橡胶材料的特性,参考旧义齿的可利用信息,可使新义齿在戴牙早期即恢复较高的咀嚼效率,降低患者对新义齿的适应时间。更多还原

【Abstract】 BACKGROUND:In complete denture repair,it is suggested to fully consult the utilized information of the old denture,which is the key to obtain a good treatment effect.OBJECTIVE:To investigate the application effect of silicone rubber materials in repair of complete denture.METHODS:Ten edentulous patients wearing the old dentures for many years,were treated with new complete dentures using the old denture renovated by skilled workers with silicone rubber.Complete denture was prepared with denture lining method on the test teeth in combination with silicone rubber impression material.Repeated measurement analysis of variance was applied to observe the changes of masticatory efficacy of two new dentures before use(the old denture) and 2 weeks,1 month,3 months,6 months after use.Another 10 patients selected according to conventional methods for denture served as the control group.RESULTS AND CONCLUSION:The treatment and time,as well as the interaction between treatment and time,had statistically significant differences on the masticatory efficiency by test denture(P < 0.01).Compared with control group at the same time point,the masticatory efficiency of experiment group was higher after wearing new dentures for 2 weeks and 1 month(P < 0.05).The masticatory efficiency after wearing new dentures for 2 weeks was significantly improved compared with old dentures(P < 0.01),but was similar to one month after wearing(P > 0.05).By means of the characteristics of silicone rubber materials and the utilized information of old denture,it is feasible to recover high masticatory efficiency of new dentures in the initial phase,and to shorten the adaptation time of patients to new complete dentures.更多还原
