一种新型人体硬组织替代材料——羟基聚磷酸钙钠植入动物颌骨的组织学研究

Study of a New Type of Material Substituted for Human Hard Tissues Hydroxyl Poly Calcium Sodium Phosphate: Histologic Report Implants in Mandible of Animals

为了初步评价羟基聚磷酸钙钠（ＨＰＰＡ）材料的组织相容性，将该材料和对照材料羟基磷灰石植入体植入到动物颌骨组织缺损区内，观察植入材料与骨组织界面作用的性质。结果发现：ＨＰＰＡ具有良好的骨结合性，能与骨组织早期形成骨性结合。本实验初步表明。

This study was aimed to evaluate the histocompatibility of hydroxyl poly calcium sodium phosphate (HPPA) preliminarily. HPPA and hydroxylapatite were implanted in the mandibular defect in dogs. The implant bone interface was obewed by using stereomicroscope and decalcified histologic sections. The result demonstrates that HPPA has well osseous integrated property after being implanted into bone tissues. This suggests that HPPA be a new material of future excellence in substitution for human hard tissues.
