纯钛支架义齿与钴铬合金支架义齿修复效果的比较

A comparative study of clinical effect for titanium and cobalt-chromium frame removable partial dentures

目的评估纯钛铸造支架义齿的临床应用效果。方法为168例肯氏Ⅰ、Ⅱ类牙列缺损的患者制作71例纯钛支架义齿和97例钴铬合金支架义齿,通过比较两组患者临床试戴情况、初戴义齿适应期的调改情况、义齿性口炎的发生情况以及满意度,评估纯钛铸造支架义齿的临床修复效果。结果纯钛支架义齿比钴铬合金支架义齿就位顺利、调改少、患者满意度高,并且义齿性口炎的发生率低。结论纯钛铸造支架义齿与传统的钴铬合金铸造支架义齿相比临床修复效果好。
