Abstract: A dental implant, including a generally cylindrical body having a proximal open end and a distal closed end and an externally threaded surface, a socket extending distally from the proximal end and terminating at a proximally facing shoulder and an internally threaded hole extending distally from the proximally facing shoulder and a curved portion formed between the proximally facing shoulder and the internally threaded wall.

Abstract: A dental abutment assembly that comprises a dental abutment having a tubular passage with an internal abutment thread at a lower end of the tubular passage, a dental implant fixture having an upper socket with an internal implant fixture thread, and a screw shaft having an upper external thread with an upper external helix twisted in a first direction and a lower external thread having a lower external helix twisted in a second direction, the upper external thread and the lower external thread are located at opposite ends of a connecting shaft. The first direction and the second direction are opposite to one another.

Abstract: According to some embodiments of the invention there is provided a dental measuring assembly comprising: an elongated stem defining a longitudinal axis between a proximal end and a distal end of the stem; a measuring abutment configured to be received over the proximal end of said stem and to axially slide over the stem; wherein a distal segment of the stem comprises scale markings denoting a height of a distal end of the measuring abutment relative to the stem. In some embodiments, a plurality of measuring abutments are provided, each abutment defining a different angle relative to the longitudinal axis of the stem.

Abstract: A dental abutment includes a projection for insertion into a cavity in the coronal portion of a dental implant. A coronal surface of the projection is adapted to be substantially flush with a coronal end of the implant when the projection is fully inserted into the cavity. A post extends in a substantially coronal direction from the coronal surface, wherein the perimeter of the post at the coronal surface is smaller than the perimeter of the coronal surface so as to form an indented shelf around the perimeter of the coronal surface.

Abstract: An abutment assembly device comprises an abutment for supporting a dental prosthesis. The abutment includes a supporting surface and an internal cavity with a rimmed opening, a hollow retainer wherein at least a portion of the retainer is flexible allowing that portion of the retainer to be inserted through the rimmed opening and snap into position retained by the rimmed opening. A screw for engaging the abutment assembly device with an implant is provided, comprising a screw body and a screw head, wherein the screw head is wider than the screw body so that when the screw is inserted trough the retainer and the retainer is retained by the rimmed opening, the screw head is retained by the retainer.

Abstract: A dental implant which contains a bi-cortical anchor apparatus for insertion into a jawbone, the anchor apparatus including a tool receptor for interacting with a tool which facilitates insertion of the apparatus. An implant member arranged for insertion into a jawbone, the member containing a cervix to secure a dental prosthesis and a through conduit to support an anchor apparatus. A complementary system including an implant member and a template, the latter meshing with and helping align the implant member. A method for inserting the implant member into a bore in the jawbone. The method includes drilling a channel in the jawbone through a drill-bit guide channel and inserting a bi-cortical anchor apparatus through the channel and through a conduit of an implant member, anchoring at least two portions of the anchor apparatus.
