Disclosed is a winged implant, which may used, by way of example only, to be applied to a bone, and may further receive a bolt or a screw. It would be desirable to have an implant that, when attempting unscrewing, will tend to resist it. Further, it would be desirable to enhance implant stability, as may be measured as an ISQ (see http://en.wikipedia.org/wiki/Implant_stability_quotient. Therefore, there currently exists a need in the industry for an implant and associated method that may tend to resist application of unscrewing torque applied thereto, and which may tend to resist bending moments and forces applied. This may be attained with the subject matter in accordance with the claims. As may be customary, implantation may take place immediately or soon after the crater is formed. Thus, the implant may be only partially lodged in solid bone, with a major portion thereof extending, substantially unsupported, to the crater, surrounded with bone fragments and congealing blood, leaving the implant to operate as a cantilever. Such mode of operation may compromise implant stability, as is well known in the art, and as may be measured as an ISQ (see above). Improved stability may enhance osseointegration (http://en.wikipedia.org/wiki/Osseointegration , incorporated herein by reference, in it’s entirety). Such requirement for stability is greatly desired particularly if immediate loading is performed subsequently to the implant procedure. As may be seen in the accompanying drawing, a winged implant may have a winged implant body (10), which may releasably secure a screw or a bolt (not shown) to a substrate, such as bone or osseous tissues (see http://en.wikipedia.org/wiki/Bone_tissue, http://en.wikipedia.org/wiki/Osseous_tissue). The winged implant body comprises an apical end and a distal end (20). A longitudinal axis L extends through the apical and the distal ends. A screwing-in direction Di may be defined about the longitudinal axis L. The distal end of the winged implant body may have at least one wing (30) extending generally radially from the distal end. The at least one wing may extend from a wing root where the at least one wing joins the winged implant body, to a wing end 126. The at least one wing may extend generally transversely to the longitudinal axis L. The at least one wing may have any desirable section. For example, and for illustrative purposes only, such wing sections may be circular, elliptic, square and / or rectangular, a general parallelogram- and / or rhomboid-shaped, and / or tear-drop shaped. Optionally, if the wing section is rhomboid, parallelogram and / tear-drop shaped, it may have a leading edge and a trailing edge. Considering the screwing-in direction Di, the leading edge is tangentially-forward and the trailing edge is tangentially rearwards relative to the screwing-in direction Di. Further optionally, if the wing section is tear-drop shaped, the leading edge may be sharp, and the trailing edge may be rounded, or blunt. Possibly, if the wing section is teardrop-shaped, a chord extending from the leading edge to a tangentially-rearmost point of the rounded trailing edge may be tilted forwardly downwardly relative to a plane perpendicular to the longitudinal axis L. A possible modification to the at least one wing is to include a support extending from the at least one wing to the distal end of the winged implant body, as is schematically shown above. During an implant procedure, an exemplary method of enhancing stability of the implant may be employed. According to such exemplary method, the winged implant body is provided with at least one wing, extending generally away from the winged implant body adjacent a distal end thereof. When the winged implant is implanted, for example in a crater which may be formed during implant procedure, the winged implant body may be further supported by the at least one wing, transforming the implant from a cantilever to a simply-supported mode of operation, thereby an enhanced stability of the implant.
