目的评价一种宽螺纹锥形种植体高扭矩植入后进行即刻负载的临床效果。方法种植体植入后即刻负载,植入1月、2月、3月时对其周围X线、种植体稳定系数、种植体颈部骨吸收等情况进行评价。结果 1所有即刻负载的种植体在1月、2月、3月时均无松动,种植体周围无X线透影区;2种植体颈部边缘有骨吸收,骨吸收在1月和2月时发生率较高,其中,单冠修复发生率多于固定桥修复(P<0.05);3种植体稳定系数在刚植入时较高、1月时最低、随后又升高,单冠及固定桥修复之间无明显差异(P>0.05)。结论此种采用高扭矩植入的宽螺纹锥形种植体,进行即刻负载有较好的临床效果,但是其长期成功率还需进一步观察。
Objective To evaluate the clinical effect of a wide-thread conical implants loaded immediately after high-torque implantation. Methods The implants were implanted immediately after implantation, and the surrounding X - ray, stability coefficient of implants and bone absorption of the neck of the implant were evaluated in January, February and March. Results 1 All immediately loaded implants showed no loosening in January, February and March, and there was no X-ray translucent area around the implants. The bone implants at the neck edge of 2 implants were absorbed in January and February (P <0.05). The stability coefficient of three implants was higher at the time of fresh implants, lowest at January and then increased again. The single crowns and Fixed bridge repair between no significant difference (P> 0.05). Conclusions This kind of wide thread tapered implant with high torque implantation has a good clinical effect for immediate loading, but its long-term success rate needs further observation.
