摘要/Abstract

摘要： 目的探讨2种不同螺纹设计的种植体在下颌磨牙区即刻负荷时对种植体和种植体周围骨界面生物学分布的影响及其骨结合情况。方法采用比格犬建立即刻种植即刻负荷模型,通过组织学实验检测双螺纹锥柱状种植体（BLX）和锥柱状种植体（BLT）2种种植体的植入精度、种植体稳定系数（ISQ）及骨结合情况,评估其在体内的稳定性和骨结合情况。结果 BLX种植体和BLT种植体在植入点总偏差、根尖点总偏差和角度偏差方面差异无统计学意义（P>0.05）;比较术后3个月双螺纹锥柱状种植体和锥柱状种植体各个方向的ISQ值,差异无统计学意义（P>0.05）;术后3个月组织学观察,发现锥柱状种植体的骨-种植体接触（BIC）和骨体积/组织体积（BV/TV）值均显著小于双螺纹锥柱状种植体（P<0.05）。结论双螺纹锥柱状设计的种植体在即刻种植即刻负荷时具有较高的初始稳定性和骨结合率,提示临床上磨牙区即刻种植即刻负荷时可优先考虑使用双螺纹锥柱状种植体。

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.
