Abstract:

Objective    To observe the clinical effect of magnetic attachment in complete overdenture in complete overdenture. Methods    Totally 22 complete overdentures were made with 52 Magfit magnetic attachments in 17 patients. The cases were observed and followed up for 6 to 18 months. The clinical results were evaluated and some related problems were observed. Results    In the 22 complete overdentures of 17 patients， there are 16 with satisfied retention，and 4 good retention；2 had improved retention. During follow-up， 2 patients had marginal gingivitis，and 1 patient had magnet detached from the denture， 1 patient with denture resin crack； they all continue to be used after being treated properly. Conclusion    Magnetic attachments are very useful in improving the function of complete overdentures. Magnetic attachments in complete overdenture can be used to improve the retention and masticatory efficiency， providing better satisfaction in patients and better results for the periodontal health of abutments.

摘要：

目的    评价磁性附着体在全口覆盖义齿中的临床应用效果。方法    对2012年11月至2013年11月于沈阳市和平区牙病防治所就诊的17例牙列缺损患者，以Magfit Ex400/Ex600磁性附着体为固位装置行全口覆盖义齿修复。共制作了22件全口覆盖义齿，使用了52枚磁性附着体。随访6～18个月，对义齿的固位效果进行评价，并对应用磁性附着体后义齿出现的问题进行观察。结果    17例患者的22件全口覆盖义齿，固位效果满意16件、良好4件、改善2件。随访中2例患者出现了龈缘炎、1例患者磁体从义齿中脱落、 1例患者义齿树脂托出现裂纹，均经适当处理后义齿继续使用。结论    磁性附着体能有效改善全口覆盖义齿的临床修复效果，为患者更好提供舒适性、咀嚼功能等主观感受，有利于牙周组织健康。
