A device for forming a dental prosthesis includes a support and an element which can be attached thereto, such as an impression element. The support has an anchoring part for anchoring in a bone or a master model, a shoulder with an annular shoulder surface, and a head. The impression element has an elastically deformable fixing agent. When the device is assembled, the fixing agent jams and/or latches with the support, either externally on the support, on the side of the shoulder facing the anchoring part, or in an axial hole of the support. The element can be quickly detachably connected to the support by placing it on top of the support, and can be quickly separated from the support by moving the support away. When the device is assembled, the support and the element can lay on top of each other with annular surfaces. The annular surfaces have fully circular outer edges which are visible from the outside in an approximately radial viewing direction.
