INTRAOSSEOUS OSTEOCONDUCTIVE DENTAL ROOT IMPLANT AND MATERIAL FOR MANUFACTURING THE IMPLANT Russian patent published in 2002 - IPC

FIELD: medicine. SUBSTANCE: device has porous root part, internal part and crown part manufactured as integral unit on the common silicate osteoconductive matrix having porosity gradient differentiated over implant height from 5-10 to 60% owing to calcium phosphates distribution. Crown part porosity gradient is equal to 5-10%. Internal part porosity gradient is 20-50%. Root part porosity gradient is equal to 40-60%. Composite material has hydroxyapatite, tricalcium phosphate, fluorapatite and silicate osteoconductive matrix. General contents of ingredients in the matrix is et 40-60% by mass, namely, hydroxyapatite - 15.0- 25.0, tricalcium phosphate - 15.0-20.0, fluorapatite - 10.0-15.0. EFFECT: enhanced effectiveness in reproducing extracted tooth or its root shape; enabled periodontal adhesion type. 2 cl, 5 dwg
