烤瓷固定夹板修复牙周病伴缺牙患者的临床应用

Clinical Effect of Porcelain Fixed Splint on Patients with Missing Teeth and Periodontal Disease

目的探讨烤瓷固定夹板修复牙周病伴缺牙患者的临床疗效。方法20例成人牙周炎患者，经牙周基础治疗后行烤瓷固定夹板修复牙列缺损，共制作义齿26例，追踪观察时间为6～24个月。通过检测牙龈指数（GI），牙周袋探诊深度（PD），临床附着水平（CAL），影像学改变以及问卷调查义齿戴入后患者的主观感受来评价修复治疗效果。结果20例患者经牙周夹板修复后，在不同的观察时间内，关键牙周指数得到改善（P〈0．05），咀嚼功能恢复良好，患者对义齿的总满意率达90％。结论采用烤瓷固定夹板修复治疗牙周病伴牙列缺损的患者，具有良好的临床效果。

Objective To investigate the clinical effect of porcelain fixed splint on patients with missing teeth and periodontal disease. Methods 20 Patients with periodontitis were treated with porcelain fixed splints after initial periodontal therapy. 26 dentures were fabricated and followed for 6 to 24 months. Gingival index （GI）, pocket depth （PD）, clinical attachment level （CAL）, image changes and questionnaires were measured and collected to evaluate the clinical effects. Results During the study period, crucial periodontal indexs of 20 patients were improved （P 〈0.05）, and masticatory fimction was restored well. Ninety percent of the patients are satisfied with the treatment. Conclusions Porcelain fixed splint can be successfully used in the patients with missing teeth and periodontal disease.
