目的观察球帽式附着体用于下颌全口覆盖义齿修复的临床效果。方法选择下颌需做全口义齿的患者52例,21例球帽式下颌全口覆盖义齿,其余31例制作传统下颌全口覆盖义齿。戴牙后1、3和6个月要求患者复诊,了解患者戴用义齿后的适应情况和对义齿的满意程度,并检查记录覆盖牙根的松动度、球帽式附着体与牙根面的密合情况以及下颌全口覆盖义齿的固位和稳定情况。结果在适应期、舒适和满意度、固位和稳定方面,SD球帽式全口覆盖义齿优于传统全口覆盖义齿。复诊期间,球帽式附着体与牙根面密合良好。1例患者在戴牙后6个月因覆盖牙根松动改行传统全口覆盖义齿。结论在覆盖牙根状况良好的情况下,SD球帽式全口覆盖义齿用于临床修复的效果明显优于传统全口覆盖义齿。
Objective To observe the clinical effect of ball-cap attachment on mandibular complete overdenture repair. Methods Fifty-two cases of complete mandibular denture were selected, 21 cases of ball-cap mandibular complete over-coverage denture, and the remaining 31 cases of traditional mandibular full-mouth overdenture. 1,3 and 6 months after wearing the teeth required patient referral to understand the patient wearing the denture after adaptation and the degree of satisfaction with the denture, and check the coverage of the root of looseness, ball-cap attachment and the root surface of the close The situation and the mandibular complete overdenture retention and stability. Results In the adaptation period, comfort and satisfaction, retention and stability, SD ball cap full denture over the traditional full denture. During the visit, the ball-cap attachment closely adheres well to the root surface.
