Method for manufacturing implant abutments for dental implants, and an implant abutment for a dental implant

Abstract

The invention relates to a method for manufacturing implant abutments 9 for dental implants 1 , wherein the implant abutment 9 comprises a prefabricated base member 8 for joining the implant abutment to the dental implant 1 , and a customized main body 15 . The aim of the invention is to simplify this method of manufacturing. To this end, the main body 15 is formed by sintering and/or melting powdery material onto the base member 8 using laser sintering and/or laser melting. The invention relates also to an implant abutment manufactured by such a method.

1 . A method for manufacturing implant abutments for dental implants, wherein the implant abutment comprises a prefabricated base members for joining the implant abutment to the dental implant, and a customized main body, characterized in that 
 the main body is formed by sintering and/or melting powdery material onto the base member using laser sintering and/or laser melting.    
   
   
       2 . Method according to  claim 1 , wherein 
 a laser beam travels point by point along a layer to be sintered and/or melted.    
   
   
       3 . A method according to  claim 2 , wherein 
 the laser beam is guided by a control unit on the basis of previously computed model data of a virtual implant abutment.    
   
   
       4 . Method according to  claim 3 , wherein 
 the base member is a connector element that is independent of the specific implant abutment.    
   
   
       5 . Method according to  claim 4 , wherein 
 the base member is prefabricated by CNC milling.    
   
   
       6 . Method according to  claim 5 , wherein 
 the base member is cast.    
   
   
       7 . Method according to  claim 6 , wherein 
 the pulverized material is titanium powder or a powder containing titanium.    
   
   
       8 . Method according to  claim 7 , wherein 
 the sintered and/or melted material is given a ceramic coating.    
   
   
       9 . Method according to  claim 8 , wherein 
 ceramic coating is performed by electrophoresis.    
   
   
       10 . Method according to  claim 8 , wherein 
 ceramic coating is performed using laser sintering.    
   
   
       11 . Method according to  claim 10 , wherein 
 the ceramic coating is not applied to the base member.    
   
   
       12 . Implant abutment for a dental implant, said abutment comprising a prefabricated base member for joining the implant abutment to the dental implant, and a customized main body, wherein 
 the main body is formed by sintering and/or melting powdery material layer by layer using laser sintering and/or laser melting.    
   
   
       13 . Implant abutment according to  claim 12 , wherein 
 it has been manufactured using a method according to  claim 1.
