Abstract: A dental prosthesis includes a dental implant, a post and core and a crown. The implant is adapted to be fixed to a bone and the post and core is adapted to be fixed to the implant with a screw that passes through the inside of the post and core, a first portion of the post and core including a first portion to be introduced into the implant and second portion protruding from the implant, providing a connection between the implant and the crown. A separation area is provided between the area where the crown is housed in the post and core and the area where the post and core is housed in the implant and the second portion of the post and core has a profile that converges from the implant toward the crown, without increases.
