PROBLEM TO BE SOLVED: To provide a configuration of a guided bone regeneration auxiliary device for implant which stably forms a new bone and improves work efficiency in guided bone regeneration performed in the case of tooth regeneration when a tooth is lost.SOLUTION: The guided bone regeneration auxiliary device 11 for implant comprises a connection member 12 and a plate 13. The connection member 12 is connected and fixed to an opening part 20 formed at one end part of a dental implant 4 in such a state as closing the opening part 20. The plate 13 is provided at one end part of the connection member 12 and projects a part or whole of an outer peripheral surface in the radial direction outward in the radial direction from an outer peripheral surface of the dental implant 4. In the state that the other end part of the dental implant 4 is buried in the jaw bone, the plate 13 stably secures a space where guided bone regeneration is performed by the guided bone regeneration auxiliary device 11 for implant for closing a part of the opening part of a space surrounded by the outer peripheral surface of the dental implant and a peripheral surface of the jaw bone.COPYRIGHT: (C)2011,JPO&INPIT【課題】歯牙欠損時の歯牙再生術の際に行なう骨誘導再生術において、安定した新生骨の形成、および作業効率の向上を図ることができる、インプラント用骨誘導再生補助具の構造を実現する。【解決手段】結合部材12と、プレート13とからなり、該結合部材12は、人工歯根4の一端部に形成された開口部20に、該開口部20を塞ぐ状態で結合固定するものであり、前記プレート13は、前記結合部材12の一端部に設けられ、径方向の外周面の一部または全部が前記人工歯根4の外周面よりも径方向外方へ突出したものであり、前記人工歯根4の他端部を前記顎骨に埋入した状態で、前記プレート13が、該人工歯根4の外周面と、該顎骨の周面とで囲まれる空間の開口部の一部を塞ぐインプラント用骨誘導再生補助具11により、骨誘導再生術を施す空間を安定して確保する。【選択図】図1
