[摘要] 目的 探讨比较应用不同材料支架义齿修复下牙列缺损的临床效果。方法 以2008—2014年在该院进行可摘局部义齿术的1 200例下牙列缺损患者为研究对象，义齿共1 452个。按照患者选择的支架义齿材料的不同，将患者分为纯钛组、钴铬合金组和Vitallium2000组。修复前，检查和记录患者的口腔情况，修复后，比较3组患者义齿就位率、2W调整率、义齿性口炎发生率、咀嚼效率、不良症状发生情况以及患者对义齿各个方面的满意度。结果 与纯钛组与钴铬合金组相比，Vitallium2 000组患者义齿就位率和咀嚼效率较高，2W调整率和义齿性口炎发生率较低，差异有统计学意义（P<0.01）；较少发生咀嚼功能不佳、发音不良等不良症状，阳性率较低，差异有统计学意义（P<0.05）；在美观度、舒适度等方面满意度更高（P<0.05）。结论 与纯钛支架和钴铬合金支架相比，Vitatlium2000支架义齿更为轻巧稳固，美观度和舒适度更高，患者咀嚼功能良好，患者的2W调整率以及义齿性口炎率降低，患者满意度提高。

[Abstract] Objective To discuss and compare the clinical effects of frame denture made of different materials for the repair of lower dentition defect. Methods 1200 cases with lower dentition defect underwent removable partial denture surgery（1452 dentures） in our hospital from 2008 to 2014 were selected as the subjects and divided into the titanium group， cobalt-chromium alloy group and Vitallium 2000 group in accordance with the material of framework denture selected by the patients. Before the repair， the conditions of the oral cavity of the patients were examined and recorded. After repair， the rate of denture in position， 2W regulation rate， incidence of denture stomatitis， chewing efficiency， incidence of adverse symptoms and patient satisfaction with various aspects of the denture of the three groups were compared. Results Compared with titanium and cobalt-chromium alloy group， Vitallium 2000 group had much higher rate of denture in position， chewing efficiency and obvious lower 2W regulation rate and incidence of denture stomatitis，The difference was statistically significant（P<0.01）； significant less poor chewing function and poor pronunciation and other adverse symptoms and lower positive rate，The difference was statistically significant（P<0.05）； and much higher satisfaction with the denture appearance and comfort and so on，The difference was statistically significant（P<0.05）.Conclusion Compared with titanium and cobalt-chromium alloy framework denture， Vitallium 2000 framework denture is lighter， solider， prettier and more comfortable with higher chewing efficiency and lower 2W regulation rate and incidence of denture stomatitis， patients are more satisfied with it.

牙列缺损是一种常见的口腔疾病，目前主要的治疗修复方式是可摘局部义齿[1-2]。不同材料的支架义齿对患者治疗效果不同，因此根据患者的病理特点、经济情况等原因选择合适的支架义齿材料，修复患者缺失的牙列，对口腔修复工作极为重要[3-4]。该研究以2008年—2014年在该院进行可摘局部义齿术的1 200例下牙列缺损患者为研究对象，观察比较不同材料支架义齿应用的临床效果，现报道如下。
