目的探讨套筒冠在牙周病牙列缺损中的应用效果。方法本文选取2008年8月~2011年7月在我院口腔科接受治疗的21例中、重度牙周病患者作为研究对象,进行套筒冠义齿修复治疗,分析其疗效。结果套筒冠义齿修复后患者主诉固位稳定,咀嚼功能恢复良好,治疗效果比较满意。经检测,本组患者的菌斑指数、牙龈指数、牙周袋深度修复前后存在明显差距(P<0.0001),健康情况明显改善;基牙松动度修复前后变化也发生明显改变(P<0.0001),基牙松动度在修复后明显好转。X片影像修复前后对比,修复前牙周膜明显变宽,骨小梁排列紊乱、疏松,骨质稀疏,修复后牙周膜变宽不明显,骨小梁排列整齐、紧凑,骨质密致。结论圆锥型套筒冠义齿能有效修复中、重度牙周病患者的牙列缺损,对病情发展起到一定的控制作用,而金合金是目前较为理想的修复材料,可优先考虑。
Objective To investigate the effect of sleeve crown on dentition defect of periodontal disease. Methods Twenty-one patients with moderate and severe periodontal disease undergoing oral stomatology in our hospital from August 2008 to July 2011 were enrolled in this study. The cuff prosthesis was repaired and the curative effect was analyzed. Results After the crown prosthesis was repaired, the patient complained of the stable position and good masticatory function. The treatment effect was satisfactory. After testing, the plaque index, gingival index and periodontal pocket depth of the patients had obvious difference (P <0.0001) before and after the repair, the health condition improved obviously; the change of abutment mobility also changed obviously before and after the repair (P <0.0001) , The abutment mobility significantly improved after the repair. Before and after X-ray image restoration, the periodontal ligament before repair was obviously widened, the trabecular arranged disorderly, loosely, the bone was sparse, the periodontal ligament broadening was not obvious after the repair, trabecular arranged neatly, compactly, . Conclusion Conical telescopic canopy denture can effectively repair dentition defects in patients with moderate and severe periodontal disease and play a certain role in the development of the disease. However, gold alloy is an ideal repair material and can be given priority.
