目的对比活动与固定义齿修复牙周病伴牙列缺损中的治疗效果。方法 86例牙周病伴牙列缺损患者,按照数学随机法分为A、B两组,每组43例。A组患者采用圆锥型套筒冠活动义齿修复,B组患者采用常规固定义齿修复。比较两组患者治疗前后的出血情况以及术后基牙的健康状况和咀嚼功能。结果修复后两组患者出血指数均有所下降,且A组下降程度明显优于B组,差异具有统计学意义(P<0.05)。B组患者术后基牙健康状况优良率90.7%以及咀嚼功能总有效率93.0%明显高于A组74.4%、76.7%,差异均具有统计学意义(P<0.05)。结论活动义齿修复用于治疗牙周病伴牙列缺损的出血情况优于固定义齿修复,但术后基牙的健康状况和咀嚼功能不如固定义齿修复,两种修复方法各有优势,具体选择哪种修复方法可根据患者实际情况确定。
Objective To compare the therapeutic effect of fixed denture with periodontal disease and dentition defect. Methods Totally 86 patients with periodontal disease and dentition defect were divided into A and B groups according to mathematical randomization, with 43 cases in each group. A group of patients with conical sleeve crown removable denture, B group patients with conventional fixed denture. The bleeding status before and after treatment and the health status and chewing function of the abutments were compared between the two groups. Results The hemorrhage index of both groups decreased after the repair, and the degree of decrease in group A was better than that in group B, the difference was statistically significant (P <0.05). The excellent and good rate of abutment dental health and the masticatory efficiency of 90.7% and 93.0% in group B were significantly higher than those in group A (74.4% and 76.7%, respectively). The difference was statistically significant (P <0.05). Conclusions Denture repair is superior to fixed denture in the treatment of periodontal disease with dentition defect. However, the health and chewing function of the abutment after operation are not as good as that of the fixed denture, and the two methods have their own advantages Methods of repair can be determined according to the actual situation of patients.
