磁性附着体覆盖全口义齿的远期疗效观察

目的：比较磁性附着体与传统卡环固位体在全口义齿修复中的远期临床效果及并发症发生情况。方法：选取我科治疗的牙列缺损患者60例,按照治疗方式分为两组,即观察组为磁性附着体义齿修复,对照组为传统卡环固位修复。随访3年并比较患者的主观满意度及客观牙周检查指标。结果：①观察组患者主观满意度包括咀嚼功能、美观性、固位情况、舒适性均明显高于对照组（P〈0.05）,提示磁性附着体对于患者的主观改善效果更为明显。②观察组患者牙龈指数、松动度、牙周袋深度以及牙槽骨高度均显著优于对照组（P〈0.05）。结论：磁性附着体在患者全口义齿修复中能更好的提供舒适性、咀嚼功能等主观感受,对于维持牙周组织健康效果明显,优于传统卡环固位体修复。

Clinical Study of Long Term Effect of Complete Over-denture with Magnetic Attachment

Objective： To compare the clinical effect of magnetic attachment and traditional clasp retainer on the treatment with complete over-denture.Method： 60 patients with complete over-denture were selected,and divided into two groups randomly.Patients in the observation group received magnetic attachment and patients in the control group received traditional clasp retainer.The satisfaction of patients and the periodontal health of abutments were observed after 3 years.Result： ①Comparison results of patient satisfaction showed that there were significant differences on the aesthetics,retention conditions and comfort between observation group and control group（P〈0.05）.②The clinical examination of periodontal pocket depth,gingival index and abutment mobility showed that there were significant differences between observation group and control group（P〈0.05）.Conclusion： Magnetic attachment in complete overdenture can be used to improve the retention and maticatory efficiency,provide better satisfaction of patients and the periodontal health of abutments.
