Patent ID: 7827694

Claim:
A method for manufacturing a dental device, in particular a one-piece dental implant, comprising the following steps: manufacturing an outer body of the dental device having a cavity, said outer body made of metal; defining a mold by said cavity and forming an inner profile of the cavity; and injecting a plastic or composite material into said mold for manufacturing an inner body having an outer profile, wherein the inner body comprises a core molded within the cavity of the outer body through said mold, a section of said core which is in contact with said inner profile of said cavity of said outer body defining said outer profile of said inner body and being complementary to said inner profile of said cavity of said outer body, wherein the inner and outer profiles are wavelike rounded in an axial direction of the dental implant and tapering from a crestal end of the outer body to a apical end of the outer body, thereby decreasing tension between the inner and the outer bodies and/or providing an anti-rotation lock between the two bodies.
