Abstract

Purpose: The impact of hyperbaric oxygen (HBO) on the healing of bone tissues around implants was studied using an animal model.

Methods: A total of 32 beagle dogs were selected and randomly divided into the HBO group and the blank group. The dogs in the HBO group were subjected to 90 minutes of HBO therapy. X-ray, cone-beam computerized tomography imaging, implant stability quotient (ISQ) values, histological observation, quantitative analysis of bone histomorphometry, and hematoxylin-eosin (HE) and Masson staining were evaluated.

Results: In this study, at 4 weeks after the surgery, the mean ISQ value in the HBO group was higher than that in the blank group, and the difference had statistical significance (P < 0.05). At week 4 and 8, the mean values of bone ingrowth fraction (BIC%) and the percentage of bone area (BA%) in the HBO group were both higher than those of the blank group. Decalcified paraffin sections were stained with HE and Masson staining showed that the bone tissue around the implant in the HBO group has more osteoblasts than control group, and many irregular marrow cavities and Haversian bone plates were observed in the new bone tissue.

Conclusion: This study showed that after implantation, early osteogenesis was better in the HBO group than in the blank group. On one hand, the healing time of the bone tissue around the implants was reduced.

高压氧对种植体周围骨组织愈合的影响。

目的:采用动物模型研究高压氧(HBO)对种植体周围骨组织愈合的影响。方法:选择32只beagle犬，随机分为HBO组和空白组。HBO组的狗接受90分钟的HBO治疗。评估x线、锥形束计算机断层成像、种植体稳定性商(ISQ)值、组织学观察、骨组织形态学定量分析、苏木精-伊红(HE)和Masson染色。结果:本研究中，术后4周，HBO组平均ISQ值高于空白组，差异有统计学意义(P < 0.05)。在第4周和第8周，HBO组骨长入率(BIC%)和骨面积百分比(BA%)平均值均高于空白组。脱钙石蜡切片HE和Masson染色显示，HBO组种植体周围骨组织成骨细胞较对照组多，新生骨组织中可见不规则的骨髓腔和Haversian骨板。结论:本研究显示，植入后HBO组早期成骨效果优于空白组。一方面，减少了种植体周围骨组织的愈合时间。
