| 摘 要： | 牙周病骨缺损是临床牙齿松动脱落的主要原因之一。本研究采用与骨组织成份相似的HAC植入牙周骨缺损区。结果证明,羟磷灰石陶瓷(HAC)与牙槽骨、牙根有良好的组织相容性。组织学观察发现,HAC植入后为新生骨组织包绕,结合为HAC-骨质复合体,可长期存留于新形成的骨组织内而不被吸收。研究结果表明HAC具有骨引导能力,是修复牙周骨缺损的良好材料。

| Abstract: | Periodontitis bone defect is one cause of tooth loss.In this research we implant HAC (Hydroxyaptite ce-ramic) a meterial similar to bone elements, into theperiodontal bone defect region in 20 cases of rabbit forinduction osteogenisis. The experimental results showthat HAC can live well with alveolar bone and toothroots. From the histomorphological observation we al-so find that after HAC is implanted into bone defect re-gion it will be surrounded by new osseous tissue, andtogether forms a comprehensive tissue, HAC--bone mix-ture. This HAC--bone mixiture can live long in thisnewly--formed bone tissue without being absorbed. Infact it has the ability to combine and stimulate bone tis-sue reproduction |
