The stress distribution of telescope and clasp removable partial dentures on the periodontal tissue was studied with strain gauge measuring. The results indicated that the stress distribution of telescope denture was more close to the intact dentitions than the clasp denture did. The telescope denture may produce physiological stimulation to the supporting tissues of edentulous area, hereby it may lengthen the service time of the natural teeth and slow the absorption of alveolar bone.
采用应变片测量法研究套筒冠和卡环可摘局部义齿在牙周组织上的应力分布。结果表明，套筒冠义齿的应力分布比卡环义齿更接近天然牙列。套筒冠义齿可能对无牙区的支持组织产生生理性刺激，从而延长天然牙的使用寿命并减缓牙槽骨的吸收。
