PROBLEM TO BE SOLVED: To provide a dental tray for impression capable of accurately taking the impression inside an oral cavity because a handle part is not brought firmly into contact with lips when the impression is taken as a preparatory step for making a complete denture as a dental prosthesis, and capable of implementing highly accurate taking of impression because the handle part can be removed if the tray is used in taking the impression for recording the position of occlusion.SOLUTION: The dental tray for impression includes: a tray body 1 having an engagement projection 1a on the apex of the dental alveolus of anterior teeth and the handle art 2 having an engagement part 2a provided at the distal end of an L shape to be engaged with the engagement projection 1a. Modes of the engagement projection 1a and the engagement part 2a include a mode in which the engagement projection 1a is a projection and the engagement part 2a is a hole to be fitted to the projections, and a mode in which the engagement projection 1a is an ant-shaped projection and the engagement part 2a is an ant groove-shaped part to slide to be engaged with the ant-shaped projection, etc.COPYRIGHT: (C)2013,JPO&INPIT【課題】歯科において補綴物として総義歯の作製を行う準備段階として口腔内の印象採得を行う際に、印象採得時にハンドル部が口唇に強く接触しないので正確に印象採得することができ、咬合位置記録のための採得時に用いる際にはハンドル部を取り外すことができて精度の高い採得が行うことができる歯科用印象用トレーを提供する。【解決手段】歯科用印象用トレーを、前歯部歯槽頂上に係合用凸部1aを有するトレー本体1と、この係合用凸部1aに係合する係合する係合部2aがL字型の先端に設けられているハンドル部2とから成る構造にする。係合用凸部1aと係合部2aとの態様としては、係合用凸部1aが突起で係合部2aがこの突起に嵌合するする穴部である態様や、係合用凸部1aがアリ状突起で、係合部2aがこのアリ状突起にスライドして係合するするアリ溝状部である態様等がある。【選択図】図3
