Abstract:
1. An implant system, comprising: a self-threading screw, comprised of titanium, configured to be inserted and osseo-integrated within a patient jaw, and having an inner upper threading; and a pin, comprised of titanium, configured for a dental crown to be coupled thereon; wherein said self-threading screw and said pin define a coupling zone therebetween when said in is coupled to a proximal end portion of said self-threading screw; said coupling zone comprises an abutment platform, which has an inclination outwardly in a proximal direction with respect to a longitudinal axis of the implant system; wherein a coronal end portion of said abutment platform being provided an annular space between an outer surface of said pin and an inner surface of said self-threading screw, said annular space being defined, in part, by an outer radial wall portion of the pin and an inner radial wall portion of the screw, wherein the inner and outer radial wall portions are generally parallel with respect to each other and to the longitudinal axis; wherein coronally of said outer radial wall portion of said pin providing an outward diverging profile, said outward diverging profile extending initially vertically and proximally with respect to the longitudinal axis as an extension of the outer radial wall portion of the pin prior to diverging radially outward in the proximal direction, and said outward diverging profile together with the annular space providing a further space for growing of gum tissues, and thus a sealing space; wherein said extension of the outer radial wall portion of the pin extends proximally beyond a proximal end of the self-threading screw; and wherein the outward diverging profile is proximally spaced from the proximal end of the self-threading screw.
