An implant fixture is disclosed. The implant fixture contains an elongated shaft section, a head section, wherein the head section comprises at least one concave area for bone growth therein, and a protrusion extending from the head section.

A novel non-metallic dental implant is provided. The implant comprises: i) a fixture to be inserted into bone, the fixture comprising a collar having a rough surface at the crest of the fixture and which tapers inwardly from a top to a neck wherein the diameter of the top is greater than the diameter of the neck, and a threaded body extending from the neck of the collar having an upper region and a lower region and comprising self-tapping threads, wherein the fixture comprises a bone compression region at the junction of the upper and lower regions of the threaded body at a site which is below the cortical bone when implanted, wherein the bone compression region comprises the widest diameter along the fixture's length; and ii) an abutment extending from the collar of the fixture. A kit comprising the dental implants is also provided.

The invention discloses a modular surgical bone screw assembly having a threaded base portion and a screw head adapted to attach a variety of structures to bone. The features of the screw include a modular design for the assembly that separates the function of anchorage to the recipient bone to one of the modules of the device (threaded portion) from the other function of attaching another element (such as bone block, membrane, orthodontic wires, elastics etc) to a second module (the screw head). The design also allows the head to be exchanged after the implant has been placed.

The present invention provides one single drill dental implant system and method for use thereof. The system comprises a multistep dental implant drill and a side cutting capability dental implant, and the multistep dental implant drill engaged with a dental handpiece to perform a dental implant step. Further, the method comprises a positioning step of aligning a tip of a drill bit portion of a multistep dental implant drill with a preset dental implant position; a drilling step of rotating the multistep dental implant drill by a dental handpiece to drill an implant hole; an expanding step of drilling the alveolar bone through a plurality of steps and cutting members of the drill bit portion, so that the diameter of the implant hole is gradually enlarged to be smaller than the diameter of a dental implant; and an implantation step of implanting the dental implant into the implant hole.

A monolithic dental implant formed from an additive manufacturing method can include a non-porous portion and a porous structure. The porous structure can increase osseointegration of the dental implant and increase the secondary stability.

A screw-shaped anchoring fixture for anchoring a prosthesis in the skull bone. The anchoring fixture comprises a main body configured to be implanted into the bone and a flange configured to function as a stop to prevent the main body from completely penetrating through the bone. The main body comprises a distal tapered apical portion, a first portion, and a second portion. The inner diameter of the second portion is greater than the inner diameter of the first portion. The method for inserting the anchoring fixture includes providing the anchoring fixture, drilling a hole, and inserting the anchoring fixture into the hole until the flange contacts the skull bone, wherein the hole has a diameter that is greater than the inner diameter of the first portion and less than the outer diameter of the second portion.

An anchor to be screwed into a hole and self-lock therein with high initial stability. The anchor has an aggressively-threaded, self-tapping apical end. A central region of the anchor is formed with a plurality of helical flutes and intervening lands. Each land carries a condensing edge. The condensing edges are configured to apply a circumferentially sweeping compressive strain to the interior surface of the host material while the anchor is being screwed into position. A coronal end of the anchor includes a corking feature to mitigate mushrooming around the perimeter of the hole. A helical groove intersects the condensing edges and flutes. The helical groove has a variable pitch and a decreasing depth which functions to squeeze and displace trapped host material thereby enhancing stability and other benefits. In bone applications, the groove hosts material chips which promote and enhance healing.

A multifunctional prosthetic component developed to have multiple functions within the conventional or digital workflow, in which a temporary or permanent prosthesis is made for a dental rehabilitation unit that is cemented or screwed on a dental implant. Thus, the component has a geometry that allows it to be used as a conventional closed tray transfer, conventional open tray transfer, scanbody, and temporary abutment, basically including three main regions: a lower region, an intermediate region and an upper region, being also able to cooperate with a positioner cap.

Dental implants, dental abutments, and dental systems are disclosed. A dental implant can include an implant body having a longitudinal axis, a coronal end, and an apical end. An internal bore can be provided within the implant body, and can have a coronal end, adjacent to the coronal end of the implant body, and an apical end. The internal bore can include a first internally facing surface, extending from the coronal end of the internal bore towards the apical end of the internal bore, at least a portion of which tapers inwardly towards the apical end of the internal bore. The internal bore can further include an internally threaded portion positioned between an apical end of the first internally facing surface and the apical end of the internal bore. A dental abutment can be configured to engage with the dental implant.

A dental implant for securing an abutment to a jawbone, the implant including a tapered body having a longitudinal axis, the body including a coronal end and an apical end, the coronal end including an inclined coronal surface. A first bore receives a base portion of the abutment, the first bore extending downwardly from the coronal surface and parallel to the longitudinal axis of the body. A second bore with a footprint larger than the first bore includes a flange adapted to be abutted by a top portion of the abutment, the diameter of the second bore being off-axis and larger than that of the first bore.
