ABSTRACT:
Disclosed is a means of locking the head of a screw to an abutting area. This is depicted in (FIG.5) reference numeral (52) whereby the screw-head is locked in place to the abutting area (26) via filling void areas (56) and (32) with plasticized materials which then become solid. The voids are such that the head of the screw (52) cannot be located in any position in relation to the abutting area (26) but that some voids and some metal projections approximate each other, partial or complete. The locking material becomes a part of a seal to the septic area of the dental implant system (FIG.6), (56) and (52). The septic area seal (FIG.2) is completed with a small layer of sealing cement in that area between the abutment (26) distal end (44) and the proximal end of the implant body (24).
