牙列缺损患者56例的修复治疗

Prosthodontic treatment for dentition defect: a report of 56 cases

目的对牙缺损患者的修复治疗进行总结分析。方法选取我院自2009年2月至2011年5月口腔科收治的牙列缺损患者56例,按照年龄分为观察组(60岁以下)和对照组(60岁以上)两组,均采用套筒冠义齿方式进行修复治疗,然后采用Bergendal的相关标准,对治疗后的整体效果分别评价并进行比较分析。结果观察组14例患者总优良率达到100.0%,优12例,占85.7%;良2例,占14.3%;对照组42例患者总优良率为95.2%,优28例,占85.7%;良12例,占28.6%;差2例,占4.8%。观察组总优良率更高,但与对照组不存在明显性差异(P>0.05);但在优、良、差三项评价中,观察组较之对照组均具有比较明显的优势,差异具有显著性(P<0.05)。另外,两组患者均未见修复体折断患者,整体效果佳,优良率达96.4%;对照组出现的2例较差患者,主要为咬合效果和稳定效果不佳。结论牙列缺损修复治疗时,应根据患者的具体情况选择合适的方式,套筒冠义齿是一种有效的牙列缺损修复方式,值得临床推广。

Objective To summarize and analyze the prosthodontic treatment for dentition defect. Methods Fifty-six patients with dentition defect who were admitted to the department of stomatology in our hospital from February 2009 to May 2011 were enrolled in the study. These patients were divided into observation group （under 60 years） and control group （above 60 years）. Both groups received prosthodontie treatment using telescopic denture. The treatment outcomes of the two groups were evaluated and compared according to Bergendal standards. Results Of the 14 cases in the observation group, 12 （85.7%） had excellent outcome, and 2 （14.3%） had good outcome, with an excellent and good rate of 100.0%. Of the 42 cases in the control group, 28 （66.7%） had excellent outcome, 12 （28.6%） had good outcome, and 2 （4.8%） had poor outcome, with an excellent and good rate of 95.2%. The observation group had a higher excellent and good rate than the control group, hut there was no significant difference between the two groups （P〉0.05）. However, the observation group had significantly higher excellent rate, good rate, and poor rate than the control group （P〈0.05）. In addition, no restorations fracture occurred in both groups patients. The overall excellent and good rate was 96.4%. The 2 cases had poor outcome mainly due to unsatisfactory occlusion effect and stability. Conclusion Proper therapy should be adopted based on the specific condition of the patient during prosthodontie treatment for dentition defect. Telescopic denture is an effective technique for treating dentition defect and worthy of clinical application.
