摘要
目的:评价一种新的齿科铸造用纯钛制作总义齿基托及可摘义齿金属支架的临床效果。方法:选择就诊于北京大学口腔医学院修复科的牙列缺损或牙列缺失患者共60例,随机分为实验组和对照组(各30例),分别采用齿科铸造用纯钛(日进株式会社,日本)与Wironit钴铬合金(BEGO公司,德国)铸造局部义齿支架或总义齿基托,于义齿戴用后1周、1个月和3个月进行复诊,检查患者佩戴义齿的临床效果,评价义齿的安全性、强度、适合性。结果:采用的齿科铸造用纯钛或钴铬合金制作总义齿基托或者可摘局部义齿支架,两种材料在安全性、强度和适合性方面无显著差异。结论:所采用的齿科铸造用纯钛可以用于临床制作总义齿基托及可摘局部义齿支架。
Objective:To evaluate the clinical effect of pure titanium used for complete denture and removable partial denture.Methods: Sixty edentulous patients were selected.Thirty patients in the test group for pure titanium denture and the other 30 in control for Co-Cr Alloy denture.Results: No significant differences in clinical effect between dental casting pure titanium and casting Co-Cr alloy used for complete denture or removable partial denture.Conclusion: Due to the properties and biocompatibility,pure titanium can be used for denture base and frameworks of removable partial denture.
