不同螺纹种植体即刻种植即刻负荷的比格犬体内实验
In vivo experiment of repairing mandibular first molar with different thread implants under immediate load in Beagle dogs
摘要
Abstract
Objective To investigate the effect of two kinds of implants with different thread designs on the biological distribution of the implant and the bone interface surrounding the mandibular molar area under immediate load.Methods Beagle dogs were employed for the immediate implantation and immediate loading model.The accuracy,implant stability quotient(ISQ),and osseointegration of the two implants were evaluated by histological analysis,and the stability and osseointegration of the two implants were evaluated in vivo.Results There were no significant differences in total error of implant point,total error of apical point,and angle error between conical cylindrical implants and double-threaded conical cylindrical implants(P>0.05).There was no significant difference in ISQ values of the two types of implants in all directions 3 months after operation(P>0.05).Histological observation at 3 months after surgery showed that conical cylindrical implants'BIC and BV/TV values were significantly lower than those of double-threaded conical cylindrical implants(P<0.05).Conclusion The double-threaded cone-column design of double-threaded conical cylindrical implants has higher initial stability and bone binding rate during immediate implantation and immediate loading,suggesting that double-threaded conical cylindrical implants should be given priority when immediate implantation and immediate loading in the molar area.关键词
