Explanation

It is a kind of biological cemmics that can be gradually degradation and absorbed in the physiological environment, and then replaced by new tissue to repair or replace damaged tissue. gypsum is the earliest bioabsorbable ceramics. Its biocompatibility is good. However, its absorption rate is too fast to match the growth rate of newly formed bone, and it is relatively less used in bone defect repair. At present, the most widely used and studied absorbable ceramics are calcium phosphate ceramics, in which a series of calcium phosphate salts (especially tricalcium phosphate) with calcium phosphorus ratio from 1:1 (CaHP04) to 1.5:1 (TCP) can be used as absorbable bioceramics. absorbable bioceramics are mainly used as materials for bone defect repair and drug carrier materials.
