Dental prosthesis, associated semi-finished product and kit

Abstract

A semi-finished product as a pre-product for a dental prosthesis having a prosthesis base, wherein the prosthesis base comprises at least one dental recess for receiving a 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.

1 . A semi-finished product as a pre-product for a dental prosthesis comprising
 a prosthesis base ( 38 ),   wherein the prosthesis base ( 38 ) comprises at least one dental recess ( 40 ) for receiving a dental arch,   wherein the prosthesis base ( 38 ) is produced to have an excess ( 70 ) at positions outside of the dental recess ( 40 ),   wherein the dental recess ( 40 ) comprises an adhesive channel ( 14 ) configured to extend along the dental recess ( 40 ) in a main direction of the dental arch.   
     
     
         2 . The semi-finished product as claimed in  claim 1 ,
 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 and extends from a palatal/lingual direction to a vestibular direction for insertion of a three-dimensionally shaped adhesive surface ( 20 ),   wherein the side branches ( 18 ) extend in the vestibular and/or palatal/lingual direction starting from the main channel ( 16 ) and terminate before a gingival margin ( 22 ).   
     
     
         3 . The semi-finished product as claimed in  claim 1 ,
 wherein the adhesive channel ( 36 ) starts at an adhesive filling opening ( 19 ) having a configuration adapted to a filling carrier ( 24 ).   
     
     
         4 . The semi-finished product as claimed in  claim 3 ,
 wherein, at the adhesive filling opening ( 19 ) of the adhesive channel ( 14 ), a syringe adapter ( 28 ) is attached either as a separate element or molded in the prosthesis base material ( 32 ), by which adapter ( 28 ) the adhesive may be inserted into the adhesive channel ( 14 ).   
     
     
         5 . The semi-finished product as claimed in  claim 1 ,
 wherein the adhesive channel ( 14 ) comprises a round cross section which is an elliptical or circular cross section.   
     
     
         6 . The semi-finished product as claimed in  claim 1 ,
 wherein the adhesive channel ( 14 ) has a smaller extension in the occlusal/gingival direction than in the palatal/vestibular direction.   
     
     
         7 . The semi-finished product as claimed in  claim 6 ,
 wherein a height/width ratio of the channel in the occlusal/gingival direction is at a height/width ratio of 1:1.1 or 1:1.5, and in the palatal/vestibular direction is at a height/width ratio of 1:5 or 1:1.5.   
     
     
         8 . The semi-finished product as claimed in  claim 1 ,
 wherein the adhesive channel ( 14 ) comprises a height H of between 0.3 mm and 5 mm or between 0.5 mm and 1.5 mm in the gingival/occlusal direction, and/or   wherein the flow area of the adhesive channel ( 14 ) at least partially decreases starting from the filling opening ( 19 ).   
     
     
         9 . The semi-finished product as claimed in  claim 1 ,
 wherein the adhesive surface ( 20 ) extending to the sides of the adhesive channel ( 14 ) comprises a thickness of between 50 and 1000 μm or between 150 and 350 μm.   
     
     
         10 . The semi-finished product as claimed in  claim 1 ,
 wherein the adhesive channel side branches ( 18 ) are each open to the sides in the mesial/distal direction, and   wherein the adhesive channel side branches merge into the adhesive surface ( 20 ) thereat.   
     
     
         11 . The semi-finished product as claimed in  claim 4 ,
 wherein the syringe adapter ( 28 ) is attached either as a separate element or molded in the dental arch material, by which adapter ( 28 ) the adhesive may be inserted into the adhesive channel ( 14 ), wherein at an end of the adhesive channel, opposite the adapter ( 28 ), a ventilation opening ( 46 ) is configured which is closed by a filter element ( 48 ).   
     
     
         12 . A semi-finished product as a pre-product for a dental prosthesis comprising
 a prosthesis base ( 38 ),   wherein the prosthesis base ( 38 ) comprises at least one dental recess ( 40 ) for receiving a dental arch,   wherein the prosthesis base ( 38 ) is produced to have an excess ( 70 ) at positions outside of the dental recess ( 40 ),   wherein the dental recess ( 40 ) comprises an adhesive channel ( 14 ) configured to extend along the at least one dental recess ( 40 ) 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 from and covers an area from a palatal/lingual direction to a vestibular direction,   wherein the side branches ( 18 ) extend in the vestibular and palatal/lingual direction starting from the main channel ( 16 ) of the adhesive channel ( 14 ) and terminating before the gingival margin ( 22 ).
