目的:观察钛合金铸造支架可摘局部义齿的临床疗效。方法:采用随机抽样的方法选取2012年3月至2014年3月我科共制作29件钛合金铸造支架可摘局部义齿,将这些义齿作为研究组,另选取28间普通金属支架可摘局部义齿和34件塑料基托可摘局部义齿分别对位对照1组和对照2组,运用调查问卷及口内义齿检查的方式综合评价义齿使用的主客观效果。结果:研究组义齿的阳性率6.9%(2/29)显著低于对照1组、对照2组17.9%(5/28)、29.4%(10/34)(P<0.05)。结论:钛合金铸造支架较普通金属支架和塑料基托可摘局部义齿的临床疗效显著,值得推广。
Objective: To observe the clinical effect of removable partial dentures on titanium alloy cast stents. Methods: A total of 29 removable partial dentures made of titanium alloy cast stents were selected from March 2012 to March 2014 in our hospital from March 2012 to March 2014. The dentures were selected as the study group. 28 common partial removable partial dentures And 34 pieces of plastic base removable partial denture were compared with control group 1 and control group 2 respectively. The questionnaire and oral denture examination were used to evaluate the subjective and objective effects of denture use. Results: The positive rate of denture in study group was 6.9% (2/29), which was significantly lower than that in control group 1, 17.9% (5/28) and 29.4% (10/34) in control group 2 (P <0.05). Conclusion: The clinical effect of titanium alloy cast stent is better than ordinary metal stent and plastic base removable partial denture, which is worthy of popularization.
