两种金属支架可摘局部义齿修复效果的临床分析

目的：评估纯钛铸造支架义齿和钴铬铸造支架义齿临床应用效果。方法：为159例牙列缺损的患者制作110件纯钛支架义齿和123件钴铬合金支架义齿，比较修复后12个月和24个月两组患者的义齿断裂、义齿固位、基牙及义齿功能，评估纯钛铸造支架义齿和钴铬铸造支架义齿的临床修复效果。结果：患者佩戴义齿12个月时，基牙疼痛及咀嚼功能不佳两项，两组间比较有统计学差异（P〈0．05），其余各项两组间比较均无统计学差异。患者佩戴义齿24个月时，各项两组间比较均无统计学差异（P〉0．05）。结论：临床观察24个月时，纯钛支架（TiRPDs）和钴铬支架义齿（Co-CrRPDs）整体成功率没有显著差异。

Comparative study on clinical effect for two different frame removable partial dentures

Objective To evaluate the clinical effect of pure titanium and Co-Cr frame removable denture. Methods 110 pure titanium frame removable dentures and 123 Co-Cr alloy frame removable dentures were made respectively and followed up.try-in,adjustment,denture stomatitis and patients,satisfaction were examined after 12 and 24 months. Results Patients wearing dentures 12 months,denture tooth pain and masticatory dysfunction in two of the abutment teeth,a significant difference （P〈0.05） between the two groups,the remaining were not statistically different between the two groups.Patients wearing dentures 24 months, were not statistically different between the two groups. Conclusion The clinical success rates at 24 months showed no difference between Ti and Co-Cr RPDs.
