| titleOfInvention | Modified artificial bone of coral with controllable degradation rate and its preparation process |
| abstract | The modified artificial coral bone with controllable degradation rate is prepared with natural coral with 3D structure as the substrate and through hydrothermal chemical reaction. The modified artificial coral bone consists of calcium carbonate in 30-70 wt% and hydroxyapatite. The preparation process of the modified artificial coral bone includes the following steps: 1.rgtg the temperature and pressure inside high pressure kettle and making natural coral change chemically to obtain the mixture of calcium carbonate and hydroxyapatite; and 2. controlling the time of chemical reaction to controlthe content of calcium carbonate and hydroxyapatite in the artificial bone. The present invention has controlled hydroxyapatite degrading rate for the implanted artificial bone to maintain in body for 1-2 years without permanent retention in body. |
