Abstract: The invention consists of a one-piece dental implant containing an endosseous part made of Ti or Zirconia high strength polymer that is screw-shaped, responsible for the mechanical fitting and biological integration into the jaw bone and that bears a transmucosal extension that acts as the supporting core of the abutment and the solid unifying element between the endosseous and the restorative part. This extension bears an esthetic coating of reduced toughness that can be ground intraorally in its coronal part to adapt the dental prosthesis after the implant has been fitted in position. The coating is ceramic or glass-ceramic or polymer and is bonded on the transmucosal-coronal extension by fusion, heat pressing or by an adhesive.
