PROBLEM TO BE SOLVED: To provide a stopper storage case for storing, in a juxtaposing state, multiple stoppers, each of which has a cylindrical shape, into which a drill for drilling a dental implant fixture implanting hole in a jawbone when performing a dental implant treatment is inserted from the cutting edge side of a blade portion, whose spring-like engagement portion is locked with a projecting flange portion provided on a shank of the drill, and which regulates the insertion depth of a drill blade.SOLUTION: Openings 3, each of which has the size of space into which the spring-like engagement portion of the stopper can be inserted, are formed at one ends of the stopper storage case, and drill blade-portion insertion paths 4, into each of which the blade portion of the drill can be inserted and in each of which top surface is opened, are formed at the other ends of the stopper storage case. A protrusion 2a, each of which is engaged with a concave groove formed in the outer peripheral surface of the stopper, are provided in stopper storing concave parts 2, which are formed respectively extending from the openings 3 to the drill blade-portion insertion paths 4 and can store stoppers X that are respectively different in length, and stopper holding protruded-rim portions 2b, which do not prevent the insertion and detachment of the stoppers, are protruded at the side portions on the top surface sides of the stopper storing concave parts 2.COPYRIGHT: (C)2012,JPO&INPIT【課題】歯科用インプラント治療を行う際に顎骨に歯科用インプラントフィクスチャー埋入用孔を穿設するドリルに刃部の刃先側から挿入される筒状を成しドリルのシャンク部に突設されているフランジ部にバネ状係止部が係止されるドリル刃侵入深さを規定するストッパを並列状態に複数個収納するストッパ収納ケースを提供する。【解決手段】ストッパ収納ケースを、一端にストッパのバネ状係止部が挿通可能な大きさの開口部3が、他端にドリルの刃部が挿通可能な上面が開口しているドリル刃部挿入路4が形成されており、開口部3からドリル刃部挿入路4に至るそれぞれ長さが異なるストッパXを収納できるストッパ収納用凹部2内にそれぞれストッパの外周面に形成されている凹溝に係合する突起2aが設けられていると共にストッパ収納用凹部2の上面側の側部にはストッパの挿入と離脱とを妨げないストッパ保持用の突条部2bが突設されている構成とする。【選択図】図1
