摘　　要：目的:观察垫式可摘局部义齿对牙齿重度磨耗伴缺牙的患者的修复效果。方法:对25例缺牙伴重度深覆患者进行取模型、用蜡堤确定颌位关系并升高咬合1mm-2mm,在上颌制作铸造支架式活动义齿,并在余留牙上制作铸造金属垫。于治疗后1、2周,1、2、3个月进行定期观察。结果:戴用义齿2周内有3例不愿继续使用义齿,其余的22例均适应了义齿并正常行使咀嚼功能,这其中有4例患者出现过牙周病加重。结论:牙合垫式可摘局部义齿能修复缺损的牙列,减小深覆,加大面下1/3的高度,是修复牙齿重度磨耗伴缺牙的一个可行修复方法。Objective： To observe the clinical effect of occlusal-splint removable partial denture for patients with severe teeth wear and tooth loss.Method： Twenty-five patients with severe deep overbite occlusal were randomly selected.Impressions were taken and occlusion relationship were fixed with wax,followed by raising occlusion 1-2mm.Casting frameworks of removable partial denture in maxillary and casting metal occlusal splint on the remaining teeth were fabricated.The follow-up time points were 1 week,2 weeks,1 month,2 month and 3 months.Result： Three individuals refused to use complete dentures within 2 weeks,while the other 22 were satisfactory in masticatory function,however with 4 cases occurred with aggravating periodontal disease.Conclusion： Occlusal-splint removable partial dentures could repair dentition defect,decrease the degree of deep overbite occlusion,and increase the height of the one-third below.It is a feasible method for repairing severe dental attrition.
