长期来活动部分义齿的设计主要根据临床经验和一般性推理来进行,缺乏客观的实验依据。为了弄清不同设计的活动部分义齿在承受咬合力时,向基牙、基托下组织(主要是牙槽嵴区)传递力量的大小与方式,以明确怎样设计才能使基牙、基托下组织既能有效地支持义齿所承受的(牙合)力,又不至于使本身受到损伤。为此,我们采用电阻应变仪法(电测法)对上颌五种类型的游离端义齿进行了实验研究。经过 For a long time, the design of some dentures is mainly based on clinical experience and general reasoning, lacking objective experimental evidence. In order to understand the activities of different parts of dentures in the acceptance of occlusal force, to the abutment, the base of the organization (mainly alveolar ridge area) the size and manner of power transfer to determine how to design in order to enable the abutment, Tissue can not only effectively support the denture (occlusion) forces, but also not to damage itself. To this end, we use the resistance strain gauge method (electrical measurement method) on the maxillary five types of free end denture were studied. after
