Embodiment

[0044] figure 2 It is a sequence diagram of a production method of a biphasic calcium phosphate-type dental medical synthetic bone graft material made of hydroxyapatite and β-tricalcium phosphate, which are bioceramics derived from abalone shells.

[0045] figure 2 The diagram shows the first step of combining hydroxyapatite and β-tricalcium phosphate derived from abalone shell; the second step of molding and surface treatment of the implanted material; the third step of sintering ; the fourth step of uniformizing the size of the graft material; the fifth step of washing and drying the graft material and finally the sixth step of sterilizing.

[0046] Specifically, the synthetic bone graft material manufacturing method 100 according to an embodiment of the present invention starts from the first step S110 of mixing hydroxyapatite and β-tricalcium phosphate derived from abalone shells. First, mix hydroxyapatite and β-tricalcium phosphate from abalone shells with 1% alginate...

Abstract

The invention provides a dental bone graft material of a biphasic calcium phosphate type using abalone shells, and a manufacturing method of the same. The dental bone graft material uses bioceramics for living donor transplantation, that is hydroxyapatite and beta-tricalcium phosphate, synthesized from shells of abalone, which are industrial waste, and is manufactured through an analysis of optimum mixing ratio for alveolar bone regeneration, internal and external surface treatment of the graft material to maximize the induction of bone tissue regeneration for dental and medical use, and biosafety and biocompatibility analysis.

Description

technical field [0001] The present invention relates to a dental medical synthetic bone graft material derived from abalone shells and its production using hydroxyapatite and β-tricalcium phosphate, which are bioceramics for in vivo transplantation synthesized from abalone shells as industrial waste, as raw materials method. Background technique [0002] For patients who need dental implants, bone grafting (Bone grafting) and Guided bone regeneration (GBR) using bone grafting material (Bone grafting material) and Guided bone regeneration (GBR) are first performed inside the bone defect for implantation. Thereby rebuilding the lost alveolar bone caused by periodontal disease. This is because the bone graft material improves the bonding force between the implant and the periodontal tissue, improves the bone regeneration effect, and is effective for new bone formation at the bone defect site filled with the bone graft material. Therefore, bone graft materials used for bone gr...
