50例磁性附着体在口腔义齿修复中的应用效果观察

目的：观察磁性附着体在口腔活动义齿修复中的应用效果。方法选择2012年4月至2014年4月于该科治疗的覆盖义齿修复患者共50例，对基牙进行预备后行磁性附着体修复，观察并记录患者咀嚼效率、满意度及修复后并发症的发生情况。结果给予磁性附着体修复后即刻咀嚼效率0．65±0．09，较修复前（0．22±0．04）咀嚼效率明显升高（t＝20．812，P＜0．05），修复后1年咀嚼效率（0．71±0．13），较修复前咀嚼效率高（t＝25．060，P＜0．05）。修复后即刻咀嚼效率与修复后1年咀嚼效率差异无统计学意义（t＝0．018，P＞0．05）。修复后即刻满意49例，较满意1例，满意度100％，明显高于修复前（46％），χ2＝31．815， P＜0．05。修复后1年满意45例，较满意5例，满意度100％，明显高于修复前（χ2＝31．815，P＜0．05）。结论采用磁性附着体修复牙列缺失或牙列缺损能明显改善患者的咀嚼效率，较传统活动义齿能明显缩短患者的适应时间，提高患者的满意度，具有广阔的临床应用前景。

Effect observation of 50 cases magnetic attachments application on oral denture restoration

Objective To observe the effect of magnetic attachments application on oral denture restoration .Methods A to-tal of 50 patients with overdenture restoration treatment in this department from April 2012 to April 2014 were enrolled .Abutment tooth were given magnetic attachments restoration after preparations .The masticatory efficiency ,patient satisfaction and post-resto-ration complication were observed and recorded .Results The immediate masticatory efficiency after magnetic attachments restora-tion (0 .65 ± 0 .09) was significant higher than that before restoration(0 .22 ± 0 .04) ,t= 20 .812 ,P< 0 .05 .After one-year′s magnetic attachments restoration ,masticatory efficiency(0 .71 ± 0 .13) was higher than that before restoration(t = 25 .060 ,P< 0 .05) .There was no statistic difference in magnetic attachments restoration between immediate masticatory efficiency and one-year masticatory efficiency(t= 0 .018 ,P> 0 .05) .There were 49 cases of immediate satisfaction and 1 case of satisfactory after restoration ,the patient satisfaction rate was 100% ,it was significant higher than that of before restoration(46% ) ,χ2 = 31 .815 ,P< 0 .05 .There were 45 ca-ses of satisfaction and 5 case of satisfactory after restoration ,the patient satisfaction rate was 100% ,it was significant higher than that of before restoration (χ2 = 31 .815 ,P< 0 .05) .Conclusion The masticatory efficiency could be improved significantly by mag-netic attachments to restore denture depletion or dentition defect ,compare with traditional denture ,it can significant shorten adapt time for patients ,and it can enhance patient satisfaction .It has wide prospect for future clinical application .
