J Clin Periodontol:不同长度种植体的周围骨密度:一项历时3年随访的随机临床试验

2017-07-17 MedSci MedSci原创

目的:短种植体经常使用,然而,关于冠 - 种植体比增加的载荷力的变化知之甚少。因此,本研究的目的是通过对随机对照的双中心临床研究获得的X线片进行评估,比较6mm和10 mm长的种植体3年期间的骨密度变化。

目的:短种植体经常使用,然而,关于冠 - 种植体比增加的载荷力的变化知之甚少。因此,本研究的目的是通过对随机对照的双中心临床研究获得的X线片进行评估,比较6mm和10 mm长的种植体3年期间的骨密度变化。

材料和方法:在标准化 X线片上选择三个预定义的区域,以评估植入物周围骨的灰度值:一个位于根尖端,另外两个在植入物的近远中两侧。所有后续使用的X线片已经使用恒定密度区域的控制场进行校准。

结果:3年后在短种植体周围,骨灰度值差异显着(p = 0.031),表明矿化程度较高。而在长种植体周围未见到这种现象。

结论:短种植体周围矿化程度高。然而这个结果是否与骨骼适应性的阻碍相关仍无定论。因此,短种植体的高失败率还须在长期临床试验中进一步研究。
