摘　　要：目的研制一种新型无冠套固定桥式牙种植体并评价其实验应用的近远期疗效。方法建立家兔牙缺失模型,分别种植传统牙种植体和无冠套固定桥牙种植体,观测其近、远期疗效的成功率。结果结果显示远期疗效中,无冠套固定桥式牙种植体的成功率明显高于对照组(P<0·05)。结论采用无冠套固定桥式种植牙修复方法,使种植义齿与邻牙相联结,减少种植牙对牙槽骨的压力,提高牙种植术的成功率。Objective To evaluate the curative effect of dental implant by crownless bridge works （CBW）. Methods The index of gingival bleeding, the index of tooth loosing and successful rate of dental implant by CBW and common dental implant on 60 rabbit models was investigated on 1, 2, 3, 6, 9, 12 month. Results The survival rate of dental implant by CBW was higher than that of common dental implant. Conclusion The dental implant by crownless bridge works can reduce the pressure to the bone and improve the successful rate of implant.
