摘要:


文题释义:
引导骨再生(guided bone regeneration,GBR):该技术通过屏障膜在软组织与骨缺损间构建生物屏障,阻隔上皮细胞及成纤维细胞侵入缺损区,为成骨前体细胞提供微环境优势,促使其优先占据缺损区并分化成熟。同时,骨移植材料作为生物支架,保护凝血块完整性,维持新骨形成所需空间架构。
血管再生:在组织修复或再生过程中,新血管从现有血管丛中生长出来的初始阶段。这一过程是生理性和病理性血管生成的重要组成部分,对伤口愈合、组织再生以及疾病进展具有关键作用。

背景:血管再生是引导骨再生成功的关键因素,但不同骨移植材料对血管再生及成骨效果的影响尚不明确。
目的:旨在比较自体骨粉与自体骨粉+人工骨粉混合在引导骨再生过程中的血管再生及成骨效果。
方法:术前通过锥形束CT扫描新西兰大白兔颌骨数据,提取兔下颌骨模型,3D打印制作截骨导板。取21只新西兰大白兔构建兔下颌骨骨缺损模型,每只兔制备双侧2个骨缺损区,其中一侧骨缺损区为自体骨粉+人工骨粉组,植入自体骨粉与人工骨粉按体积比1∶1混合材料;另一侧骨缺损区为自体骨粉组,仅植入自体骨粉材料。于造模后2,5,7,14 d及4,8,12周检测骨缺损区的血管再生及成骨情况。
结果与结论:①术后第12周,自体骨粉组与自体骨粉+人工骨粉组的组织形态观察及血管再生情况相似;②自体骨粉组血管断面数量在2-
7 d表现出更为显著的上升趋势,其他周期两组的血管断面数量变化趋势接近;③术后8周时自体骨粉+人工骨粉组的新生骨分布范围不如自体骨粉组大,12周时,两组骨组织的连续性和致密性均较佳,接近正常骨组织形态;④第8周时,自体骨粉组的骨体积分数明显高于自体骨粉+人工骨粉组(P < 0.05),至第12周时,自体骨粉+人工骨粉组与自体骨粉组的骨体积参数对比差异无显著性意义(P > 0.05);⑤结果表明,早期自体骨粉植入的血管和骨再生现象更明显,但到术后12周,自体骨粉+人工骨粉混合植入与单纯自体骨粉植入修复兔下颌骨缺损的效果相近,说明随着骨改建过程的进行,两种材料的综合效果趋于一致。

Abstract: BACKGROUND: Angiogenesis is a key factor in the success of guided bone regeneration, but the impact of different bone graft materials on angiogenesis and osteogenic effects remains unclear.
OBJECTIVE: To compare the angiogenesis and osteogenic effects of autologous bone powder and the mixture of autologous bone powder and artificial bone powder during guided bone regeneration.
METHODS: Preoperative scanning of the jawbone data of New Zealand white rabbits using cone beam CT was performed to extract a rabbit jawbone model, which was then 3D printed to create a bone cutting guide plate. Twenty-one New Zealand white rabbits were used to construct a rabbit mandibular bone defect model. Two bone defect areas were prepared on both sides of each rabbit, with one side of the bone defect area consisting of autogenous bone and artificial bone powder and a 1:1 mixture of autogenous bone powder and artificial bone powder was implanted. The other bone defect area was taken as the autologous bone powder group, with only autologous bone powder material implanted. Angiogenesis and osteogenesis in both bone defect areas at 2, 5, 7, 14 days and 4, 8, 12 weeks after modeling were detected.
RESULTS AND CONCLUSION: (1) At 12 weeks after surgery, the histological morphology and angiogenesis of the autologous bone powder group were similar to those of the autologous bone powder + artificial bone powder group. (2) The number of vascular cross-sections in the autologous bone powder group showed a more significant upward trend from 2 to 7 days, while the change trends of the number of vascular cross-sections in the two groups were similar in other periods. (3) At 8 weeks after surgery, the distribution range of new bone in the autologous bone powder + artificial bone powder group was smaller than that in the autologous bone powder group. At 12 weeks, the continuity and compactness of the bone tissue in both groups were good, close to the morphology of normal bone tissue. (4) At 8 weeks, the bone volume fraction of the autologous bone powder group was significantly higher than that of the autologous bone powder + artificial bone powder group (P < 0.05). By 12 weeks, there was no significant difference in the bone volume parameters between the autologous bone powder + artificial bone powder group and the autologous bone powder group (P > 0.05). These results indicate that angiogenesis and bone regeneration are more obvious in the early stage after implantation of autologous bone powder. However, by 12 weeks after surgery, the mixture of autologous bone powder and artificial bone powder is similar to pure autologous bone powder implantation in the repair of rabbit mandibular defects. This suggests that as the bone remodeling process proceeds, the comprehensive effects of the two materials tend to be consistent.
