磁性固位技术的临床应用研究

Research on clinical application of magnetic retentive technology

目的:探讨磁性附着体在临床修复中的作用。方珐:分别采用日本生产Magfit各型磁性附着体,以磁力为固位形式,对32例牙列缺失及牙列伴牙槽骨缺损病例进行修复,并对患者主观感觉和临床客观检查结果进行分析。结果:磁性附着体义齿(MA)修复组的咀嚼效率明显提高,各组间咀嚼效率比较差异有统计学意义(P< 0.01)。修复前与常规义齿修复组比较咀嚼效率差异有统计学意义(P<0.01);常规义齿修复与磁性附着体义齿修复比较。咀嚼效率差异有统计学意义(P<0.01)。结论:与常规义齿比较,磁性附着体义齿修复更能提高咀嚼效率,义齿固位良好且美观。

Objective： To probing ways of application and effects of different types of magnetic attachments （MA）in clinical prosthesis. Methods. Treating 32 patients who bade lost teeth worth Magfit Ex600, denture individually, compared the reaction of patients and clinical results. Results： The masticatory efficency of MA was better than denture. Conclusion： Application Magfit attachments fits the biomechamical principles. It can improve the retention, masticatory efficency comparing to traditional denture.
