目的探讨钴铬合金支架可摘局部义齿及纯钛支架可摘局部义齿在牙列缺损患者修复中的临床应用效果。方法 98例牙列缺损患者,按修复材料的不同将其分为对照组(钴铬合金支架可摘局部义齿)与观察组(纯钛支架可摘局部义齿),各49例。对比两组修复效果。结果观察组患者6个月就位率、初戴2周调改率分别为91.84%、10.20%,优于对照组患者的73.47%、48.98%;观察组患者义齿性口腔炎发生率为12.24%,低于对照组的26.53%,差异均具有统计学意义(P<0.05);观察组患者美观满意度、语音满意度、咀嚼功能满意度、固位功能满意度及舒适满意度均明显高于对照组,对比差异均具有统计学意义(P<0.05)。结论同钴铬合金支架可摘局部义齿相比,纯钛支架可摘局部义齿在牙列缺损患者中的修复效果更为良好,具有较高临床推广价值。
Objective To investigate the clinical effects of removable partial denture with cobalt-chromium alloy stent and removable partial denture with titanium stent in the repair of dentition defect. Methods A total of 98 patients with dentition defect were divided into control group (Cobalt - chromium alloy removable partial denture) and observation group (Pure Titanium stent removable partial denture) according to the different repair materials, with 49 cases in each group. Compare the two groups repair effect. Results The 6-month placement rate in the observation group was 91.84% and 10.20% at 2 weeks, respectively, which was better than 73.47% and 48.98% in the control group. The incidence of denture stomatitis in the observation group was 12.24% , Which was lower than that of the control group (26.53%) (P <0.05). The aesthetic satisfaction, speech satisfaction, masticatory satisfaction, retention satisfaction and comfort satisfaction of the observation group were significantly higher than those of the control group Control group, the difference was statistically significant (P <0.05). Conclusion Compared with the removable partial denture with cobalt-chromium alloy stent, the removable partial denture with titanium stent can be more effective in repairing dentition defect and has higher clinical promotion value.
