摘　　要：影响全口义齿的因素很多，其中义齿的固位和适合度对其功能的行使有密切的关系。本文采用软性衬垫材料，对２２名戴用全口义齿后因固位不良、疼痛等以致咀嚼效能下降者进行加衬治疗，并在治疗前后，采用吸光度法进行咀嚼效能的测定比较。结果表明全口义齿的固位和适合度与咀嚼效能关系密切。加衬治疗后的全口义齿，由于固位改善、适合度提高，其咀嚼效能立即有了明显改善。治疗后的咀嚼效能平均是治疗前的２０９％。接受治疗的病例中，９０％以上患者是下颌义齿，说明戴全口义齿后下颌变化明显大于上颌。作者认为，软性衬垫材料对牙槽嵴及粘膜条件较差者和年老体弱者是一种适宜的材料。There are many facts of effection on complete denture. Retention and adaptation are vrey important to denture's function among them. This thesis uses soft relining material for 22 complete denture's patients whose pain, non-retention and etc. resulted in the decline of masticatory efficiency to be treated. Masticatory efficiency is measured and analysed by light absorption method after treatment. The result shows there is closed relationship between full denture's retention and adaptation and masticatory efficiency. After relining, patient's masticatory efficiency is greatly improved due to increasing retention and adaptation. the masticatory efficiency after/before treatment is average 209%. Among these patients,mandibule changes are larger than maxilla.Author considers that soft relining is a good material for poor condition of alveolus dentis,mucosa and for old fragile man.
