In our department we have done quite number of HA sphere implantation cases gained satisfactory result in recent years.

近年来，在我们科已做了相当数量的羟基磷灰石义眼台植入，都取得了满意的效果。

It is well known that hydroxyapatite is a biocompatible material with good osteoconductivable properties. It has been known that HA can promote early bone ingrowth.

众所周知，羟基磷灰石具有良好的生物相容性和骨传导能力，在临床上用于骨缺损的修复已有几十年的历史。

Objective To observe the clinical effect and factors of hydroxylapatite and iodoform combination as repairing perforated molar pulp.

目的 研究复方羟基磷灰石碘仿糊剂用于修复磨牙髓室底穿孔的临床疗效及影响因素。

Results: Fresh nHA-PA66 paste and polymerized nHA-PA66 films showed no antimicrobial activity to Sm and little to Av and Lc. After mixed with the iodoform, the antimicrobial activity of nHA-PA66/I paste obviously increased, but no significant difference between nHA-PA66/I and CH. There was no antimicrobial activity of HA to the three test bacterial strains.

结果：抗菌实验结果表明，nHA-PA66固化膜片与nHA-PA66糊剂对Sm无抑菌作用，对Av和Lc有极轻微抑菌作用，膜片与糊剂之间无显著性差异；加入碘仿后的nHA-PA66糊剂抑菌能力显著增强，与氢氧化钙相比无显著性差异，常规羟磷灰石对三种实验菌均无抑菌作用。

Hydroxyapatite/poly lactide biomaterial has become one of the most important and potential bone graft substitutes because of its favorable biocompatibility and bioactivity.

羟基磷灰石/聚乳酸复合材料以其良好的生物相容性和生物活性成为骨替代材料中较重要、较有潜力的一部分。
