宗旨和目标
软衬主要用于全口义齿，用于粘膜条件差的情况下，并用于咀嚼力的均匀分布。然而，对于软衬垫的弹性是否会干扰咀嚼功能存在一些疑问，因为义齿佩戴者可能需要额外的力来压缩软衬垫，导致肌肉疲劳。因此，本临床研究旨在评估和比较使用软衬和不使用软衬的全口义齿患者的咀嚼性能。
材料和方法
20名无牙颌受试者被选为研究对象。每例患者制作两套全口义齿。第一套不使用软衬，第二套使用软衬。选择花生作为研究的测试食物，将咀嚼的食物合并用于单次测量，然后倒在筛子上。收集过滤器和滤液并离心。本研究中的咀嚼性能通过将通过筛子的测试食物的体积除以回收的测试食物的总体积来定量。然后将该分数表示为百分比。
结果
经配对t检验，使用软衬与不使用软衬的全口义齿患者的咀嚼效能有显著性差异。平均性能差异为5%。
结论
本研究得出的结论是，与佩戴全口义齿而不使用软衬的患者相比，佩戴使用软衬的全口义齿的患者的咀嚼性能提高了5%。
临床意义
本研究显示，全口义齿患者使用软衬后，咀嚼效能有明显改善。
AIMS AND OBJECTIVES
Soft liners are mainly used with complete dentures in case of poor mucosal conditions and for the even distribution of masticatory forces. However, there is some doubt as to whether the elasticity of the soft liner disturbs masticatory function because denture wearers may need extra force to compress the soft liners, leading to muscle fatigue. So, this clinical study was done to evaluate and compare the masticatory performance in patients wearing complete dentures with and without the use of soft liners.
MATERIALS AND METHODS
Twenty edentulous subjects were selected for the study. For each patient two sets of complete dentures were fabricated. First set without the use of soft liner and the second one for using with soft liner. Peanuts were selected as test food for the study and the chewed food was pooled for a single measurement and then poured on sieves. Both filter and filtrate were collected and was centrifuged. Masticatory performance in this study has been quantitated by dividing the volume of test food passing through the sieve by the total volume of test food recovered. The fraction is then expressed as a percent.
RESULTS
With the paired t-test performed, significant difference was found between the masticatory performance in patients wearing complete dentures with and without the use of soft liners. 5% difference was seen in the mean performance.
CONCLUSION
It has been concluded from this study that, masticatory performance in patients wearing complete dentures with the use of soft liners was improved by 5% when compared to the patients wearing complete dentures without using soft liners.
CLINICAL SIGNIFICANCE
This present study indicates that the masticatory performance enhanced with the use of soft liners for complete denture patients.
