Fabrication of carbonate apatite block based on internal dissolution-precipitation reaction of dicalcium phosphate and calcium carbonate.
In this study, we investigated a novel method for fabrication of carbonate apatite block without ionic movement between precursor and solution by using precursor that includes all constituent ions of carbonate apatite. A powder mixture prepared from dicalcium phosphate anhydrous and calcite at appropriate Ca/P ratios (1.5, 1.67, and 1.8) was used as starting material. For preparation of specime...
متن کاملFabrication and Physical Evaluation of Gelatin-Coated Carbonate Apatite Foam
Carbonate apatite (CO₃Ap) foam has gained much attention in recent years because of its ability to rapidly replace bone. However, its mechanical strength is extremely low for clinical use. In this study, to understand the potential of gelatin-reinforced CO₃Ap foam for bone replacement, CO₃Ap foam was reinforced with gelatin and the resulting physical characteristics were evaluated. The mechanic...
متن کاملThe expanded amelogenin polyproline region preferentially binds to apatite versus carbonate and promotes apatite crystal elongation
The transition from invertebrate calcium carbonate-based calcite and aragonite exo- and endoskeletons to the calcium phosphate-based vertebrate backbones and jaws composed of microscopic hydroxyapatite crystals is one of the great revolutions in the evolution of terrestrial organisms. To identify potential factors that might have played a role in such a transition, three key domains of the vert...
متن کاملCell-mediated bioresorption of sintered carbonate apatite in rabbits.
Bone apatite contains carbonate and is therefore not pure hydroxyapatite. We have successfully developed sintered carbonate apatite (CA) with a concentration of carbonate of 6 weight% and have evaluated its osteoconductive and bioresorption characteristics. Cylindrical porous sintered CA and sintered hydroxyapatite (HA) measuring 4 x 4 mm with a porosity of 20% were implanted into surgically-cr...
متن کاملResorption of Sintered Carbonate Apatite Implanted in Rabbits
Introduction The ideal bone substitute is a material that can be completely replaced by newly formed bone. Hydroxyapatite has been widely used as a bone substitute because of its excellent biocompatibility and osteoconductive ability. The clinical application of hydroxyapatite may be limited, because it does not seem to be resorbed appreciably. In order to improve these disadvantages, we have s...
