Mechanisms for securing an abutment, removable prosthesis, and/or a fixed prosthesis to an implant without screws or cement are provided. At least a portion of an abutment and/or a fixed prosthesis may be formed from a resilient material to enable the abutment and/or the fixed prosthesis to be secured to secured to the implant without screws or cement. Alternatively, a removable prosthesis may include a spring-loaded snap fastener for securing the removable prosthesis to an implant without screws or cement. The spring-loaded snap fastener may include a metal coil having at least three turns disposed in a same plane. The spring-loaded snap fastener may secure the removable prosthesis to the implant by at least gripping a groove disposed at least a partially around an interface between the removable prosthesis and the implant.

The invention relates to surgical and orthopedic dentistry, particularly to implantology, more particularly to apparatus for mounting a dental prosthesis at the site of a missing tooth, and more particularly to dental (tooth) implants. Proposed is an implant which consists of a base section, an abutment and a connecting screw, said abutment having a conical surface with a total angle of 7-9, and lobes positioned in the inner gingival region, and said screw being threaded with a pitch of 0.20.05 mm. The implant has enhanced strength, particularly when in the form of narrow prostheses.

A method of damping compressive, tensile, and lateral compressive and tensile forces on one or more prosthetic teeth and an implant recessed into jawbone through use of synthetic periodontal ligament fibers in the form of a damping membrane within a dental bridge assembly. An arcuate damping membrane positions on a full bar and a half-bar positions over the membrane; whereby the damping membrane is sufficiently resilient to enable lateral and axial movements by the prostheses affixed to the half-bar.

A force damping dental bridge assembly which damps compressive, tensile, and lateral forces on a prosthetic tooth and jawbone through use of synthetic periodontal ligament fibers in the form of a damping membrane. Multiple layers of arcuate components and Morse taper interconnections secure the assembly. A threaded implant that penetrates the jawbone defining a tapered, conical inner cavity which receives a shank protruding downwardly from a full bar. An arcuate damping membrane positions on the bar and a half-bar positions over the membrane; whereby the damping membrane is sufficiently resilient to enable lateral and axial movements by the prostheses affixed to the half-bar. A plurality of protuberances extend from an upper surface of the half-bar to enable sculpting and affixation of prostheses thereon; and whereby a plurality of fasteners detachably connect the prostheses to the bar and/or implants in a snap-fit relationship that can be detached with an implement adapted to unsnap the assembly from a patient's mouth.

A dental implant system includes an anchoring part of a ceramic material for anchoring in bone tissue, an abutment of ceramic material, and an abutment screw. The anchoring part has a recess that is open towards a coronal end for engagement of a fastening post of the abutment. The abutment has an opening that is continuous in the axial direction and into which the abutment screw can be inserted. The abutment screw is configured, for a fastening of the abutment to the anchoring part, to engage into an inner thread that is formed on the anchoring part in the recess or is present on an insert element that is inserted into the recess. The abutment screw has a screw head, and a shoulder, which is formed coronally and which together with the screw head forms a stop on inserting the screw into the opening, is present in the opening.

A dental implant system includes an anchoring part of a ceramic material and an insertion tool. The anchoring part includes an outer thread that defines an axis. The anchoring part has a recess for an engagement of a fastening post of an abutment as well as for an engagement of an insertion tool, the recess being open towards the coronal end. The recess has an inner structure region with an inner structure that forms an insertion geometry for interacting with a corresponding outer structure of the insertion tool, and the insertion tool has an engagement portion with the corresponding outer structure. The recess forms a support region coronally of the inner structure region, wherein a transition region with a surface which in the longitudinal section is concavely arcuate and/or conical is formed between the support region and the inner structure region.

Implants for anchoring within bone are provided herein. An implant may include at least one thread extending around a core in a plurality of turns from the coronal region to the apical region. The thread(s) has a thread outer diameter that may define a cylindrical portion, wherein the thread outer diameter remains constant for more than one turn around the core, and define a conical portion, wherein the thread outer diameter decreases at a thread diameter decrease rate in the apical direction. The thread(s) may have a plurality of notches spaced radially and longitudinally from one another. The notches may be partially notched to reflect a portion of a semi-spherical surface and partially notched to reflect a portion of a semi-cylindrical surface.

The present invention relates to an anchoring system for attaching a prosthesis to a human body, comprising: an anchoring element, an abutment, an abutment screw for attaching the abutment to the anchoring element, the anchoring element comprises a connection area for the abutment, the connection area comprising a press-fit portion such that the abutment is attached to the anchoring element in the connection area by a press-fit connection, wherein the connection area comprises an anti-rotation geometry and the abutment comprising a corresponding mating anti-rotation geometry proximal to the press-fit portion, and where in the connection area comprises a conical portion proximal to the anti-rotational geometry forming a mating geometry for a corresponding conical portion in the through-hole of the abutment.

A dental implant includes an internal passage/shaft extending down from the top of the implant with a connection structure that includes, at/near the opening into the internal passage, a lead-in bevel configured for insertion of a post, abutment, or other insert, into the passage, below the lead-in bevel, inside the passage, an internal wrench-engaging surface; and, below the internal wrench-engaging surface, inside the passage, another beveled portion, inside the implant, configured to mate with the insert/abutment/post, to form an interference fit.

A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.
