A dental implant including a core; at least one screw thread; a first and second region; a central axis; the surface of the core defining an angle with the central axis in the first region and with the central axis in the second region; and the surface of the screw thread defining an angle with the central axis in the first region and with the central axis in the second region. The diameter of the core decreases at a rate in the first region towards the apical end such that the core defining angle is greater than the screw thread defining angle, and the diameter of the core decreases at a rate in the second region towards the apical end such that the core defining angle is the same as the screw thread defining angle. Furthermore, an implant including at least one helical chamber including a depth and length.

The secondary part (17) according to the invention, for securing on and/or in a dental implant, is suitable for receiving a tertiary part. The secondary part (17) comprises a secondary-part body (22) with a recess (21) on the inside, and a secondary-part screw (20) receiveable or received in the recess. The secondary part (17) has a screwing-in mechanism in the form of a contour for receiving a screwing-in tool for screwing the dental implant, connected to the secondary part (17), into a jawbone.

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.

Highly self-tapping dental implant system with hybrid cone type connection and interlocking rails, which allows high insertion (or removal) torque and double parallel cone locking between the implant, prosthetic abutment and internal screw, even in its 3.0 mm diameter embodiment, and gives the whole system high primary and secondary stability, optimal watertightness thanks to the double cone sealing, as well as predictable long-term fixation of the dental prosthesis on the implant.

The secondary part (17), for securing on and/or in a dental implant, is suitable for receiving a tertiary part. The secondary part (17) has a secondary-part body (22) with a recess (21) on the inside, and a secondary-part screw (20) receivable or received in the recess. The secondary part (17) has a screwing-in mechanism in the form of a contour for receiving a screwing-in tool for screwing the dental implant, connected to the secondary part (17), into a jawbone.

An implant device includes an implant with a threaded portion and a drilling portion and a positioning hole respectively formed at two ends of the implant. Channels are recessedly formed on an outer surface of the implant. Each channel includes pore units joined one another in a row. An interior of each pore unit includes a first area enclosed by a peripheral wall and a second area defined between adjacent surface portions and communicating with the first area. The peripheral wall has first projecting units formed thereon to present a surface with concavities and convexities. Second projecting units extend outwards from adjacent peripheral walls and overlap one another between every two adjacent channels to define each surface portion. Cells derived from a target part are quickly attached to the channels and linked with each other for enhancing the combination between the implant and the target part.

The present invention relates to a dental implant having at least one but preferably a plurality of split fins that are vertically spaced along the vertical axis of the body portion of the implant. These split fins hold the body portion of a dental implant stationary within the patient's jaw by engaging the patient's jawbone and promoting osseointegrationthe growth bone around and on the surface of the implant. Each split fin has a first end that is vertically spaced from a second end along the implant body's vertical axis such that the split fin extends from the first end and around the body's circumference along an inclined plane until it terminates at the second end so that the split fin creates a single spiral that extends around the entire circumference of the body portion of the implant.

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.

A method provides a modular dental implant. The modular dental implant has (a) an implant apex comprising an internal fastening surface; (b) a first hollow implant body segment; (c) an abutment having a screw access hole; and (d) a fastening screw. The method also entails fastening the external fastening surface of the first hollow implant body segment to the internal fastening surface of the implant apex; and screwing the fastening screw (i) through the abutment and the first hollow implant body segment, and (ii) into the implant apex, when the abutment, the first hollow implant body segment, and the implant apex are fastened together.
