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