Components for improved impression making

Abstract

The invention relates to components for an improved system for pick-up impression making at a dental implantation site, including an abutment, an abutment replica and an impression coping. The invention also relates to a series of abutments and to a set comprising an abutment and an impression coping. The abutment includes an implant contacting region and a component support region, the component support region has a maximum diameter and extends coronally of the maximum diameter to a coronal end. The component support region also includes a component engagement arranged for releasable engagement with the component by linear displacement of the dental component in relation to the abutment. The component engagement is located at a position closer to the maximum diameter than to the coronal end of the component support region.

What is claimed is:  
     
         1 . An abutment for connection of a dental component to an implant, comprising: 
 an implant contacting region; and    a component support region, said component support region having a maximum diameter and comprising: 
 a shoulder portion presenting a maximum shoulder diameter and an outer surface tapering inwardly in a coronal direction of said shoulder portion from said maximum shoulder diameter;  
 a post portion extending coronally from said shoulder portion to a coronal end of the abutment and presenting an outer surface forming an angle less than 180° with said outer surface of said shoulder portion; and  
 a component engagement arranged for releasable connection of the dental component to said abutment by linear displacement of the dental component in relation to the abutment, said component engagement being provided at said post portion, at a position being closer to said shoulder portion than to said coronal end.  
   
     
     
         2 . An abutment for connection of a dental component to an implant, comprising: 
 an implant contacting region; and 
 a component support region, said component support region having a maximum diameter and comprising:  
 a shoulder portion presenting an outer surface;  
 a post portion extending coronally from said shoulder portion to a coronal end of the abutment and presenting an outer surface forming an angle less than 180° with said outer surface of said shoulder portion; and  
 a component engagement arranged for releasable connection of the dental component to said abutment by linear displacement of the dental component in relation to said abutment, said component engagement being provided at said post portion, at a position being closer to said shoulder portion than to said coronal end and coronally spaced from said maximum diameter.  
   
     
     
         3 . An abutment for connection of a dental component to an implant, comprising: 
 an implant contacting region; and    a component support region, said component support region having a maximum diameter and comprising: 
 a shoulder portion presenting an outer surface;  
 a post portion extending coronally from said shoulder portion to a coronal end of the abutment and presenting an outer surface forming an angle less than 180° with said outer surface of said shoulder portion, wherein the outer surface of said post portion tapers inwardly in a coronal direction of said post portion from a maximum post diameter; and  
 a component engagement arranged for releasable connection of the dental component to said abutment by linear displacement of the dental component in relation to said abutment, said component engagement being provided at said post portion, at a position being closer to said shoulder portion than to said coronal end.  
   
     
     
         4 . An impression coping for pick up impression making of a dental abutment attached to a dental implant, comprising: 
 an abutment surrounding region, for surrounding said abutment, said abutment surrounding region having a coronal end and an apical end, and having an inner wall provided with an abutment engagement arranged for releasable engagement with the abutment by linear displacement of said impression coping in relation to said abutment, said abutment engagement being located closer to said apical end than to said coronal end,    wherein said abutment surrounding region comprises an apical portion having an inner wall and a post surrounding portion extending coronally from said apical portion and presenting an inner wall forming an angle larger than 180° with said inner wall of said apical portion, wherein said abutment engagement is provided at the post surrounding portion, at a position being closer to the apical portion than to the coronal end of the abutment surrounding region.    
     
     
         5 . The impression coping according to  claim 4 , wherein said apical portion is a shoulder contacting portion.  
     
     
         6 . An abutment replica, comprising a component support region having an outer shape of the component support region of the abutment according to  claim 1 , including a replicated component engagement.  
     
     
         7 . A set comprising the abutment according to  claim 1  in combination with the dental component.
