三种缓冲机制的根面附着体式覆盖义齿的电测应力分析研究
Study on electrical measurement stress analysis of root attachment overdenture of three different mecha-nisams
摘要
Abstract
Objective To analyze the stress difference of alveolar bone around the abutment and alveolar ridge of edentulous of three different kinds of root-attachment-supported overdenture under different load conditions, in order to provide a reference for the choice of clinical root attachment. Methods The occlusal force of overdenture was simulat-ed by electrical resistance strain measurement in vitro. The stress of the alveolar bone, the central part of the mandibu-lar arch and the first molar correspond to the alveolar ridge were measured. The stress difference of 3 kinds of attach-ment overdenture under different loading conditions were compared and analyzed. Results Under the same loading condition, all three kinds of overdentures had a certain degree of slip of the denture (magnetic attachment denture) or ro-tation (3 kinds of attachment dentures). The abutment neck in different parts of the dental arch and alveolar bone, anteri-or free end edentulous alveolar ridge stress distribution was significantly different. Conclusion ERA attachment over-denture was the most preferable, followed by the magnetic attachment overdenture. Suitable attachment should be select-ed based on specific clinical cases.关键词
