In this study, we aimed to study the effects on new bone formation of autogenous blood, deproteinized bovine bone graft (DBBG), and biphasic calcium phosphate (BCP) bioceramic graft materials placed under titanium barriers.
Twenty-four adult male New Zealand white rabbits were used in this study. Two titanium barriers were fixed on each rabbit's calvarium. The study included four groups, one of which was a control group. The experiment groups, autogenous blood, DBBG (Bio-Oss(®) ; Geistlich Biomaterials, Wolhusen, Switzerland) and BCP (4Bone(TM) ; Biomatlante, Vigneux de Bretagne, France) were placed under titanium barriers; in the control group, no materials were used. Half of the animals were sacrificed after 1 month, and the rest were sacrificed after 3 months. After this, micro-computerized tomography images were taken, and a histomorphometric evaluation was carried out.
The amounts of new bone formation were found to be higher at the third month than at the first month. The differences between the groups were examined with both a micro-computerized tomography and histomorphometric analysis, and no statistical significance was noted in the first month. In contrast, the increase in the amount of new bone formation at the third month was found to be statistically significant only between the DBBG and control groups (P < 0.05).
Autogenous blood with titanium barriers in guided bone regeneration seems to be as successful as DBBG and BCP bioceramic graft material.
本研究旨在研究自体血、脱蛋白牛骨移植物(DBBG)和双相磷酸钙(BCP)生物陶瓷移植物材料置于钛屏障下对新骨形成的影响。
本研究使用了 24 只成年雄性新西兰白兔。每只兔子的颅骨上固定了两个钛屏障。研究包括四个组,其中一个是对照组。实验组分别为自体血、DBBG(Bio-Oss®;Geistlich Biomaterials,Wolhusen,瑞士)和 BCP(4Bone®;Biomatlante,Vigneux de Bretagne,法国),置于钛屏障下;对照组则不使用任何材料。一半的动物在 1 个月后被处死,其余的在 3 个月后被处死。之后,进行了微计算机断层扫描图像采集和组织形态计量学评估。
发现第 3 个月的新骨形成量高于第 1 个月。通过微计算机断层扫描和组织形态计量学分析对各组进行了检查,在第 1 个月没有发现统计学差异。相比之下,只有在 DBBG 和对照组之间,第 3 个月新骨形成量的增加才具有统计学意义(P<0.05)。
在引导骨再生中,带钛屏障的自体血似乎与 DBBG 和 BCP 生物陶瓷移植物材料一样成功。
