摘要:

背景:异种脱细胞真皮基质属于口腔修复膜材料,因具有良好的生物相容性而被广泛应用。
目的:评价异种脱细胞真皮基质在牙区引导牙种植骨再生的效果。
方法:以免疫组化染色后显微镜观察异种脱细胞真皮基质的显微结构和细胞相容性,评价应用在引导骨再生技术中的可能性。对应用异种脱细胞真皮基质引导骨再生的牙种植修复患者进行观察随访,评价成骨效果以及对缺损软组织的影响,并与Bio-Gide生物膜以及博特医用胶原膜等其它修复膜引导骨再生的效果进行比较。
结果与结论:异种脱细胞真皮基质的显微结构显示其有基底膜面和组织面,基底膜面可见指突结构和毛囊孔,组织面为鳞片状结构,对成骨样细胞的增殖活力和碱性磷酸酶的活性无影响,具有良好的细胞相容性。临床研究显示在牙种植中应用异种脱细胞真皮基质引导骨再生能够获得良好的骨再生效果,与Bio-Gide生物膜以及博特医用胶原膜引导骨再生的效果无明显差异,并且用于修复骨增量后软组织的不足同样能够获得较好的骨再生效果。

Abstract:

BACKGROUND: Acellular dermal matrix is a kind of prosthodontics membrane material which has been widely used due to the good biocompatibility.
OBJECTIVE: To evaluate the effect of acellular dermal matrix in guiding bone regeneration in the dental implant area.
METHODS: Immunohistochemical staining was performed, and the microscope was used to observe the microstructure and cell compatibility of acellular dermal matrix, in order to evaluate the feasibility of acellular dermal matrix in guiding bone regeneration. The dental implantation patients who received bone regeneration with acellular dermal matrix were followed-up to evaluate the osteogenesis effect and the effect on soft tissue defects. Then, the effects of Bio-Gide membrane and Bot medical collagen membrane on guiding bone regeneration were compared.
RESULTS AND CONCLUSION: The microstructure of acellular dermal matrix showed there was basement membrane surface and tissue surface. The stylode-like structure and hair follicle could be observed on the basement membrane surface and the tissue surface was scaly structure, and acellular dermal matrix had no influence on the proliferation activity osteoblast-like cells and the alkaline phosphatase activity, but had good cell compatibility. The clinical researches showed that acellular dermal matrix used in dental implantation was effective for bone regeneration, and there was no significant difference in the effect on guiding bone regeneration when compared with Bio-Gide membrane and Bot medical collagen membrane. The acellular dermal matrix had good bone regeneration effect in repairing soft tissue deficiencies after bone augmentation.
