Abstract: The present disclosure concerns a set for the production by 3D printing of implant abutments for dental implants, the set including at least one abutment having an elongated base member with an axis, and at least one positioning element fixed to the base member; a plate with at least one recess and a locking portion; where the recess is larger than the elongated base member and where the locking portion is configured to be in a form fit connection with the positioning element in order to vertically position the abutment, and lock the abutment in rotation around its axis.

Abstract: A mounting element for a dental prosthesis, the prosthesis including at least one bridge, the mounting element and prosthesis being formed using 3D printing, where the mounting element has an axis of elongation and comprises an engagement portion, for fixedly engaging the prosthesis and an attachment portion, for enabling secure attachment of the prosthesis to the jig during machining, the mounting element further comprises a registration portion for aligning, in use, the prosthesis in a precise position and/or orientation on a jig during machining, the registration portion comprises a tapering portion having a conically tapering outer surface.
