Abstract
An arrangement and an implant are provided for increasing the stress resistance of the implant arranged in an upper jaw bone (1). The implant has access via parts (9, 4′) to the sinus cavity (5). At said parts, the implant is arranged with a convex or rounded front surface which, upon access, lifts the sinus mucous membrane, without piercing the latter, and thus forms a closed space (7) between the parts and the underside of the mucous membrane. The implant is provided, at least at said parts, with growth-stimulating substance or substances (15) which interact with cell-containing body fluid (8) which penetrates or has penetrated into the space, so that new bone (11) is formed around said parts of the implant.
Claims8
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 configured to pass through the patient's upper jaw bone and to push but not pierce 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 at least a part of the outer surface coated with GSS 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 the surface of the upper jaw bone and to form a closed space between the surface of the upper jaw bone and the pushed mucous membrane;
- and
- allowing the GSS to be released from the implant surface and to interact with fluids deposited in the closed space so as to form new bone in the closed space.
