摘要
目的:评价不同种类深覆牙列缺损修复的临床效果,探讨深覆牙列缺损的临床分类、诊断与修复方法的选择。方法:将46例深覆牙合牙列缺损的患者根据上前牙的倾斜情况、是否存在上前牙的缺失以及后牙的磨耗情况分为四类,根据每一类的缺失和咬合特点分别采用不同的修复方法,包括固定修复、固定和可摘义齿联合修复及可摘义齿修复,其中38例患者进行咬合重建,于修复治疗后分别检查义齿的使用情况与患者的面形及颞下颌关节健康状况。结果:46例患者随访1-5年,咀嚼效能提高,其中38例咬合重建的患者面形改善明显,颞颌关节症状基本缓解。经统计学分析,四类深覆牙列缺损的病例所选择的三种修复方法存在显著性差异(x2=27.32,P<0.005)。结论:对于需进行修复的深覆牙合牙列缺损患者,根据其临床分类及诊断选择不同修复方法,可取得满意的临床疗效。
Objective： To evaluate the clinical effect of different kinds of deep overbite patients with detition defect, and to discuss the clinical classification, diagnosis, and the choice of prosthetic methods. Methods： Forty-six patients with deep overbite and dentition defect were divided into four categories according to the incline of their maxillary incisor, lack of maxillary incisor, attrition of posterior teeth. According to each kind of detition defect and occlusal features, we adopted dif- ferent prosthetic methods, including fixed prosthesis, fixed prosthesis combined with removable partial denture and remov- able partial denture （RPD）. Thirty-eight patients were treated with occlusal reconstruction. After prosthetic treatment, the service conditions, face form and the health of temporomandibular joint （TMJ） were evaluated. Results： 1-5 years follow-up results of 46 patients showed that masticatory efficiency of patients was obviously increased and the face forms of the 38 patients with occlusal reconstruction were improved significantly with improved health of TMJ. Conclusions： As for the prosthetic treatment for deep overbite patients with detition defect, selecting prosthetic methods according to the clinical classification and diagnosis could obtain satisfactory clinical curative effect.
