作者在下颌单侧游离端义齿的模拟模型上,设计金属、厚度、形态皆不同的舌杆,测得其负重水平变位量,探讨了舌杆对抗基托颊舌侧旋转所需要的强度。实验用的舌杆是用钯—银合金、铂—金合金和钴—铬合金分别铸造成舌杆与舌板、以及用成品杆用Co—Cr合金线弯制而成,舌板宽7mm、厚 The author designed the tongue with different thickness, shape and shape on the simulation model of unilateral mandibular free end denture. The level of displacement of the mandible was measured, and the intensity of the tongue against the buccolingual lingual rotation was discussed. The experimental tongue is made of palladium-silver alloy, platinum-gold alloy and cobalt-chromium alloy, respectively, into a tongue and tongue plate, and finished rod made of Co-Cr alloy curved, tongue width 7mm, thick
