目的:总结磁附着体覆盖义齿修复的临床效果。方法:选取牙列缺损需进行磁附着体覆盖义齿修复的患者86例。经基牙根管治疗、根帽制作、义齿制作、义齿试戴、完成磁附着体义齿修复。观察磁体固定前、固定后即刻、固定后6周义齿的固位力,测定患者咀嚼效率及不良反应发生情况。结果:磁附着体义齿修复后即刻固位力、固定后6周固位力和即刻咀嚼效率、固定后6周咀嚼效率均优于磁体固定前,且差异具有统计学意义(P<0.05)。经磁附着体义齿修复后,出现1例不良反应,表现为牙周炎,不良反应发生率为1.16%。结论:磁性附着体用于口腔覆盖义齿修复,能够有效提高固位力及咀嚼效率,不良反应少,临床效果好。
Objective: To summarize the clinical effect of magnetic attachment overdenture repair. Methods: Totally 86 patients with denture defect undergoing magnetic attachment overdenture repair were selected. The root canal treatment of root canal, root cap production, denture production, denture try to complete the magnetic attachment denture repair. The fixation of the denture was observed 6 weeks after the fixation, immediately after the fixation, and the masticatory efficiency and adverse reactions of the patients were observed. Results: The retentive force, the repositioning force and immediate mastication efficiency at 6 weeks after fixation were significantly higher than those before magnet fixation (P <0.05). One case of adverse reactions appeared after the magnetic attachment denture was repaired, which showed periodontitis. The incidence of adverse reactions was 1.16%. Conclusion: Magnetic attachments for oral overdenture repair, can effectively improve the retention and chewing efficiency, fewer adverse reactions, clinical effect is good.
