Abstract
アバットメントとフィクスチャーを内部に挿入して累合させて形成する2ピースタイプの咀嚼力等の外力によっても結合が強固で緩みにくい歯科用インプラントを提供する。
【解決手段】
大小2種類の半円弧曲面が連続的に連なった円弧歯車形状を接合面全面に有する凸状の接合部を具えたアバットメントと前記上部接合体の凸状の接合部と接合面全面で嵌合する大小2種類の半円弧曲面が連続的に連なった円弧歯車形状を有する凹状の装着部を具えたフィクスチャーの接合構成により、両者を接合する接合ネジのねじ部と、フィクスチャー(4)内部のねじ部の累合結合の緩みを防止する。
【選択図】図1
Description
本発明で用いるアバット、ヒーリングアバットのネジ山の形状はネジ部の長さが比較的短いために締結力低減、噛み付き防止が期待できる。
