Objective: The objective of this study is to test whether the self-made denture adhesive paste can improve the chewing efficiency of complete denture.Methods: The abilities to improve chewing efficiency of two different materials, including self-made and Fixodent denture adhesive paste, will be investigated in this experiment. 24 patients were randomly selected, who wore complete dentures or mucous membrane supporting removable partial dentures because of the loss of most teeth. Identical test method was adopted by chewing peanuts. By employing a spectrophotometer, the absorbency values of chewed peanuts suspension before and after the use of self-made denture adhesive pasties were measured, and the differences could be obtained by calculation. The differences indicated the relationship between denture adhesive paste and chewing efficiency. Then the results of two materials would be compared and analyzed.Results: The statistical analysis revealed that both self-made denture adhesive paste and Fixodent resulted in remarkable difference in the absorbency values before and after use (P<0.01), however, there is no obvious difference in improving the chewing efficiency between the self-made and Fixodent denture adhesives (P>0.05).Conclusion: The self-made denture adhesive paste is the same as Fixodent in improving the chewing efficiency of denture.%目的:评价强力义齿稳固剂改善总义齿咀嚼效能的能力。方法: 随机选择戴有总义齿的无牙颌患者和采用粘膜支持式可摘局部义齿修复的多数牙缺失患者共24例，采用同体比较法，花生米作试料，分光光度计测定咀嚼后花生米悬浊液的吸光度，测定强力义齿稳固剂使用前后吸光度值的变化。观察义齿稳固剂与咀嚼效能的关系,并与国外产品Fixodent比较。结果: 数据统计分析表明，强力义齿稳固剂和Fixodent使用前后吸光度值的变化均具有显著性差异（P<0.01）；而两种稳固剂使用后吸光度值的大小无显著性差异（P>0.05）。结论: 强力义齿稳固剂同国外产品Fixodent一样能明显提高义齿的咀嚼效能。
