1·OBJECTIVE: To observe the effective characteristics of carbonated hydroxyapatite cement on repair of skeletal defect by animal experiment.

目的：通过动物实验观察碳酸化羟基磷灰石水泥修复骨缺损效果的特征。

2·In vitro test of the rate of weight losses demonstrated that the dissolution of carbonated hydroxyapatite cement was better than the calcium phosphate cement.

失重率的检测表明，酸化羟基磷灰石骨水泥的失重率改变明显高于磷酸钙骨水泥。

3·BACKGROUND: Carbonated hydroxyapatite cement is a new type material for skeletal repair and hydroxyapatites have been applied in the clinical treatment of skeletal defect.

背景：碳酸化羟基磷灰石骨水泥是一种新型的骨修复材料，已应用在骨缺损临床治疗中。
