摘　　要：目的:研究磁性附着体用于牙列缺损修复的临床效果及对牙周微生态的影响。方法:选取2014年8月至2015年8月我院接诊的80例牙列缺损患者作为研究对象,按照随机数表法分为观察组40例和对照组40例。对照组采用常规修复,观察组采用磁性附着体治疗,观察两组患者治疗后固定力、咀嚼效力、舒适程度、语言功能、外观及牙周微生态。结果:治疗后,观察组固定力、咀嚼效力大于对照组[(4.07±0.38)N vs(3.10±0.29)N,(0.80±0.23)%vs(0.59±0.21)%],两组比较差异具有统计学意义(P<0.05);观察组舒适程度、语言功能、外观均优于对照组[(4.21±0.45)score vs(3.10±0.42)score,(4.79±0.50)score vs(3.90±0.42)score,(3.98±0.61)score vs(2.76±0.56)score],两组比较差异具有统计学意义(P<0.05);观察组PLI、PD显著小于对照组[(1.34±0.31)°vs(1.49±0.43)°,(1.53±0.29)mm vs(1.67±0.32)mm],两组比较差异具有统计学意义(P<0.05)。结论:磁性附着体治疗牙列缺损疗效显著,能够减少对牙周组织的损伤,提高舒适度和咀嚼功能。Objective：To study the curative efficacy of magnetic attachment in the treatment of repair of dentition defect and its effects on the periodontal micro ecology.Methods：80 patients of defect of dentition who were treated from August 2014 to August 2015 in our hospital were selected as the research objects.The control group was treated with routine repair,while the observation group was treated with magnetic attachment.Then the fixation force,masticatory effectiveness,comfort level,language function,appearance,periodontal micro ecology in two groups after treatment were compared.Results：After treatment,the fixed force,chewing effect of observation group were better than the control group[（4.07± 0.38）N vs （3.10± 0.29）N,（0.80± 0.23）% vs （0.59± 0.21）%]（P〈0.05）;the comfort level,language function,appearance were better than the control group [（4.21± 0.45）score vs （3.10± 0.42）score,（4.79± 0.50）score vs （3.90± 0.42）score,（3.98± 0.61）score vs （2.76± 0.56）score]（P〈0.05）;the PLI,PD were less than the control group [（1.34± 0.31）＆#176; vs （1.49± 0.43）＆#176;,（1.53± 0.29）mm vs （1.67± 0.32）mm]（P〈0.05）.Conclusion：Magnetic attachment was effective for the repair of dentition defect,which could reduce the damage to periodontal tissue and improve the comfort and chewing function.
