Abstract
A dental prosthesis having a prosthesis base and a set of teeth, namely a full set of teeth or a partial set of teeth, is provided, wherein the prosthesis base comprises at least one dental recess for receiving the set of teeth, and wherein the set of teeth is glued into the at least one dental recess by an adhesive. In the dental recess and/or in or at the set of teeth an adhesive channel is configured which extends along the at least one dental recess or the dental arch in its main direction of extension. It starts at an adhesive filling opening whose configuration is adapted to a filling element.
Claims16
A dental prosthesis comprising
- a prosthesis base (38),
- a dental arch (36), and
- an adhesive for adhering the prosthesis base and dental arch together,
- wherein the prosthesis base (38) comprises at least one dental recess (40) for receiving the dental arch (36), and
- wherein the dental arch (36) is glued into the at least one dental recess (40) by the adhesive,
- wherein the dental recess (40) and/or at the dental arch (36) comprise an adhesive channel (14) configured to extend along the at least one dental recess (40) or the dental arch (36) in a main direction of the dental arch,
- wherein starting from the adhesive channel (14) which is configured as a tree-structure comprising a main channel (16) from which side branches extend away from the main channel (16), the main channel (16) extends centrally at a basal side of the dental arch and extends from a palatal/lingual direction to a vestibular direction, a three-dimensionally shaped adhesive surface (20) extends between the dental arch (36) and the prosthesis base (38) and reaches gingival margin (22),
- wherein the side branches (18) extend in the vestibular and/or palatal/lingual direction starting from the main channel (16) and terminate before the gingival margin (22).
