老年人牙列重度磨耗伴牙列缺损垫式可摘局部义齿的修复

Occlusal Splint Removable Partial Dentures for Restoration of Severe Attritional Occlusion Accompanied with Dentition Defect in the Elderly

目的探讨垫式可摘局部义齿修复老年人牙列重度磨耗伴牙列缺损的临床疗效。方法对37例牙列重度磨耗伴牙列缺损患者,先行修复设计,然后进行过渡塑料垫式可摘局部义齿的修复,每月复查并调改至最适颌位。观察3~6个月后,制作永久性垫式可摘局部义齿修复,嘱6个月复诊1次。结果 37例患者中双重建者13例,单重建者24例;随访2年,垂直距离得到恢复,咀嚼功能明显改善,肌疲劳感消失,颜面及外形、发音功能恢复良好,修复体对口腔软组织无损伤。结论老年患者由于牙列重度磨耗导致的咬合垂直距离降低有必要进行咬合重建修复,而永久性垫式可摘局部义齿修复可取得满意的效果。

Objective To investigate the clinical effect of occlusal splint removable partial dentures for restoration of severe attritional occlusion accompanied with dentition defect in the elderly.Methods Severe attritional occlusion accompanied with dentition defect was restored by the transition of plastic dental splint removable partial dentures in 37 elderly patients after restoration design.Patients were reviewed monthly for locating the optimal jaw position.After observation for 3-6 months,the permanent occlusal splint removable partial dentures were prepared for restoration.Then patients were asked a return visit per 6 months.Results Among the 37 patients,13 were restored by the two occlusal reconstruction and 24 were restored by a single occlusal reconstruction.After 2 years of follow-up,vertical distance was restored,chewing function was improved,muscle fatigue disappeared,the face and form and the function of pronunciation recovered well.The restoration did not create damage to oral soft tissue.Conclusion It is necessary for the elderly patients with reduction of occlusal vertical dimension induced by severe attritional occlusion to perform occlusal reconstruction.The permanent occlusal splint removable partial dentures can lead to satisfactory results.
