Arrangement for increasing the stress resistance of implants and one such implant

An implant for insertion into an upper jaw bone of a patient in need thereof, the implant comprising:

• a convex or rounded front surface being designed to cooperate with a sinus mucous membrane in a sinus, via an underside of the sinus mucous membrane, to form an enclosed space between the implant and the underside of the sinus mucous membrane,
• the implant being coated with at least one growth-stimulating substance (GSS),
• wherein at least the front surface and parts of the implant penetrating into the sinus are arranged to interact with cell-containing body fluid to form new bone around the front surface and the parts of the implant penetrating into the sinus,
• wherein the implant comprises at least one outer thread, and
• wherein the GSS is coated only on a side of a tip of the implant.

• a convex or rounded front surface which is designed to cooperate with a sinus mucous membrane in the sinus, via an underside of the sinus mucous membrane, to form an enclosed space between the implant and the underside of the mucous membrane;
• an anchor for securing the implant to the upper jaw bone;
• and,
• at least one screw for fastening the anchor to the upper jaw bone,
• wherein at least the front surface and parts of the implant penetrating into the sinus are coated with at least one growth-stimulating substance (GSS) arranged to interact with cell-containing body fluid to form new bone around the front surface and the parts of the implant penetrating into the sinus.
