23 Jul Production method of bone tissue engineering scaffold material artificial tooth root capable of improving synostosis
Abstract
The invention provides a production method of a bone tissue engineering scaffold material artificial tooth root. The method includes the six steps of: preparing a steel model, preparing an initial green body of the artificial tooth root, processing pores, filling the pores with a PLLA/nHA composite, spray-coating the green body with a PGA/nHA composite coating, and performing surface degradation.In the invention, the initial green body of the artificial tooth root is prepared with a PEEK and HA crystal whisker composite material as a bone tissue engineering scaffold material, wherein at corresponding positions on the green body, pores are processed and are filled with the degradable PLLA/nHA active composite material; finally, the green body is spray-coated with the PGA/nHA bioactive coating and then surface degradation is carried out to produce the bone tissue engineering scaffold material artificial tooth root capable of improving synostosis function. The artificial tooth root can be combined with bone through self-repairing on bones with bone induction cells, so that the elasticity modulus of the tooth root is matched with alveolar bone better, and bone absorption of the alveolar bone is not liable to be caused. The artificial tooth root is greatly better than a common artificial tooth root.
