    • PURPOSE: Spherical hydroxy apatite particles have a variety of medical uses, including bone replacement, implant coatings, and dental applications such as alveolar ridge augmentation, root extraction site fillings, restoration of periodontal osseous lesions, and soft tissue augmentations. CONSTITUTION: A process is provided for producing spherical, non-porous hydroxy apatite particles having a size which does not exceed 250 microns and having a density of at least 3.00 g/cc. The process comprises agglomerating in the presence of water as the only additive hydroxy apatite powder feed stock having a purity of at least 97 %, and having metallic impurities which do not exceed 500 PPM, to form hydroxy apatite particles having a size which does not exceed 350 microns. The particles are then dried and then sintered at a temperature from about 1,100°C to about 1,200°C to provide spherical, non-porous hydroxy apatite particles which do not exceed 250 microns and having a density of at least 3.00 g/cc.

    • An implant with bone tissue infiltrative osseointegration is provided to make hydrogel expand into tissue liquid around the implant by applying a hydrogel including growth factor facilitating formation of bone on the surface of an implant. An implant with bone tissue infiltrative osseointegration is coated with a hydrogel or a composition including a hydrogel. The hydrogel is a derivative of hyaluronic acid acrylate of formula 1, in the formula 1, n is 4 to 8. The above composition includes a material that can help the attachment of cells or induce or facilitate the formation of blood vessel and the formation of bone. Said growing factor is one or more selected among bone morphogenic protein-2, BMP-4, BMP-6, BMP-7, IGF(insulinlike growth fadtor)-1, IGF-2, FGF(fibroblast growth factor), PDGF(platelet derived growth factor), TGF(transforming growth factor)-beta, VEGF(vascular endothelial growth factor), fibronectin, and vitronectin.
