摘　　要：目的测试分析长正中型总义齿的咀嚼效能。方法用解剖型和线性型作对照,采用多筛法测定长正中型总义齿的咀嚼效能,并应用Rosin-Rammler等式对检测结果进行描述。结果应用SPSS13·0随机配伍组方差分析检验显示咀嚼至吞咽前时,长正中型与解剖型总义齿的X50和b值之间的差异均没有统计学意义(P>0·05),而线性型总义齿是通过增加咀嚼次数(P<0·05)而获得了与长正中型、解剖型相似的X50和b值(P>0·05)。结论长正中型总义齿具有良好的咀嚼效能。Objective To study the masticatory efficiency of the long-centric occlusal pattern complete dentures. Methods Multiple seive method was used to evaluate the masticatory efficiency of the long-centric occlusal pattern complete dentures. The Rosin-Rammler equation was used to describe the particle size distribution of the comminuted test food. Linear occlusal dentures and anatomic occlusal dentures served as control. Results At the end of mastication, there was no statistical difference in the value of X50 and b between the long-centric occlusal pattern complete dentures and anatomic occlusal dentures and linear occlusal dentures. However, linear occlusal dentures were similar in masticatory efficiency to the other two occlusal pattern complete dentures by increasing the masticatory strokes before swallowing（P 〈 0. 05 ）. Conclusion The long-centric occlusal pattern complete dentures functioned very well for edentulous patients.
