Patent ID: 8771361

Claim:
A method of using an implant in a sinus cavity of a patient comprising: obtaining an implant having a length, an outer surface at least partially coated with a growth stimulating substance (GSS), and a rounded front part having a polished part and configured to pass through an upper jaw bone of the patient and to push but not pierce a mucous membrane adjacent the sinus; forming a hole in the upper jaw bone adjacent the sinus cavity of the patient; inserting the implant through the formed jaw bone hole such that the partially coated portion of the outer surface extends beyond the formed hole and into the sinus cavity; pushing the mucous membrane of the sinus cavity with the rounded front part of the implant so as to lift the mucous membrane from a surface of the upper jaw bone and to form a space between the surface of the upper jaw bone and the pushed mucous membrane; and allowing the GSS to be released from the partially coated portion of the outer surface of the implant and to interact with fluids deposited in the space so as to form new bone in the space; wherein the rounded front part has a front surface and the front surface comprises the polished part and is designed with a surface roughness or porous layer at sides thereof, and the surface roughness or porous layer functions as a reservoir for layers of GSS.
