Since October 1978, in cooperation with other unit, we have used the method to spray Al_2O_3 or ZrO_2 ceramic powder on the surface of the artificial bone and joint, which is made of TC_4 metal, to form a ceramic coat with myriads of tiny holes from 0.3mm to 0.6mm in diameter and from 50μm to 60μm in thickness.
The independently produced CHA artificial bone is white in color,with porosity of 25.87%-53.58%,which is approximate to those of the human bones and the original coral,by Mohs hardness of 3-4 and compressive strength of 4.87-12.31 MPa.
Objective To study the biocompatibility of Co/N-TCP and the ability of Co/N-TCP to precipitate the repair of bone defect when nano-composite artificial bone (Co/N-TCP) were implanted the region of bone defect.
ObjectiveTo study revascularization issues of compound artificial bone through compounding nano-hydroxyapatite / chitosan (N-HA/CS) with bone morphogenetic protein (BMP).
In order to investigate the effect of hCbfa1 adenovirus vector on the artificial bone transplant, hCbfa1 cDNA gene was cloned to construct the recombinant adenovirus vector.
A method was established for determination of major calcium and phosphorus in artificial bone by ICP-AES. The test of sample dissolving,interference of coexist elements were studied.
Objective To investigate the ectopic osteogenesis of bone marrow stromal cells (MSC) induced by bone morphogenetic protein(BMP) in vitro and in vivo , providing the experimental evidence for making an artificial bone with its own capacity of bone formation.
With the increasingly improvement of the living standard,people want the damaged bone to be repaired more perfect. Rapid prototyping technology could efficiently fabricate artificial bone.
This technology combines rapid prototyping manufacture technology with chemical vapor infiltration technology. Artificial bone can be fabricated in shorter period.
Though carbon/carbon composite has excellent biologic capability, it is very difficult to be made into artificial bone that has complex shape using traditional technics.
We developed an artificial bone substitute for such strut grafts in order to overcome availability restrictions and potential infectious hazards with allograft bone.
The maximum adhesive strength of the apatite layer to the specimen was significantly higher than that to the commercially available artificial bone, HAPEXTM.
In this experimental study, we propose a new method obtaining porous CaCO3 monolith for an artificial bone substitute.
The third scaffold was prepared using three-dimensional gel-lamination, a new rapid prototyping method, and was named as hydroxyapatite artificial bone.
Practical implication may involve a biomimetic artificial bone or cartilage can be made through a precipitation method with suitable bio-organics.
