ERA种植覆盖义齿修复颌骨并牙列缺损的临床评估

Retrospective investigation of clinical application of ERA implant overdenture on jaw bone defect and dentition defect

目的:临床研究颌骨并牙列缺损采用ERA种植覆盖义齿进行修复的效果。材料与方法:23例的颌骨并牙列缺损患者采用ERA种植覆盖义齿修复。结果:经过1年至5年时间随访,100%的患者表示对该义齿的固位性能,咀嚼效能,舒适程度,以及装卸的方便程度感到满意。142个种植体,有2个病例6个月时出现4个种植体松动,进行了即刻补种,其余无失败病例。结论:ERA种植覆盖义齿进行修复颌骨并牙列缺损患者,临床观察患者非常满意,提示该方法是一种方便、经济、可靠的修复方式。本组病例应用美国Sterngold公司生产的太极扣(ERA)和Branemark系统,Implanmed种植体及太极扣种植体,ITIMark系统,XIVE系统等种植体。采用带血管腓骨瓣等移植完成骨基础重建,然后进行同期或延期种植,最后完成种植太极扣覆盖义齿修复。对23例颌骨缺损(142个种植体、63个扣)缺失牙病例进行了种植覆盖义齿修复,采用的是粘固桥式支架连接,太极扣固位,由于大量骨缺损,所以大量采取种植体支持,覆盖修复重建良好外形。观察1月-5年。有5个病例中间经过修理或更换阳扣,有一个病例修复后5个月牙龈退缩,6个病例有牙龈增生,3个有明显骨吸收。本题通过对太极扣临床应用种植体太极扣完成各类颌骨缺损后的修复。探讨太极扣赝附体修复的设计方法,以及移植骨吸收原因和规律,以及阴阳、太极概念的理论意义。

Objective:To evaluate the effect of clinical application of ERA implant overdenture on jaw bone defects and dentition defect.Methods:23 cases that were not satisfied with traditional removable denture were applied by ERA implant overdenture.Results:23(100%)cases that were satisfied with the new dentures.142 implants,4(2.8%)implants were failed but repaired quickly and easily.Conclusion:ERA implant overdenture was a better choose than with traditional removable denture on jaw bone defects and dentition defect.
