摘    要:目的:研究磁性附着体在单颌全口覆盖义齿中的临床修复效果。方法:20例患者,单颌选择1-4个基牙放置磁性附着体制作全口覆盖义齿,其中上颌全口覆盖义齿患者5例,下颌全口覆盖义齿患者15例,共采用41个磁性附着体。在修复后1个月、3个月、6个月、1年、2年、3年、4年及至今5年分别进行回访复查,主要观察固位体周围牙龈的健康状况,基牙松动度,继发龋,义齿的固位,稳定性,咀嚼效率的变化及舒适度。对义齿咀嚼效率的变化及舒适度衡量主要依赖患者的直接主观感受。结果:患者对义齿的舒适性和稳定性均表示满意,3个基牙出现松动,2个基牙出现继发龋,1个磁体脱落,其余良好。结论:采用磁性附着体的单颌全口覆盖义齿可以提高义齿的舒适性和稳定性。

Abstract:Objective: To study the five years clinical restoration effects of single complete overdenture with magnetic attachment. Methods: Twenty patients were restored with complete overdenture in which one to four magnetic attachments were used. It included 5 maxilla complete overdenture patients and 15 mandible complete overdenture patients. Fourty-one magnetic attachments were used. The gingiva health, mobility and secondary carried of abutment teeth were observed at one month, three months, six months, one year, two years, three years, four years and five years after restoration. Result: All patients were satisfied with the comfort and stability of the complete overdenture with magnetic attachment. Three abutment roots lost stability, secondary caries occurred in two abutment roots, a magnet retainer failed. Conclusion: Complete overdenture with magnetic attachment can improve the comfort and stability of the denture.
Keywords:magnetic attachment  denture  overlay  denture  complete  stability
