An abutment arrangement for connecting a dental restoration to a dental implant, including a post body and a screw element. The post body has an expansion part and the screw element includes a spreading section. The passage extends through the expansion part of the post body. An outer diameter of the expansion part of the post body is elastically increasable by applying a lateral force. The passage of the post body has a pressure receiving section at the expansion part. When the screw element is located in the passage of the post body, the spreading section of the screw element is arrangeable at the pressure receiving section of the passage of the post body such that the lateral force is applied to the expansion part of the post body and the outer diameter of the expansion part of the post body is increased.

In a dental implant (1) comprising a post part (2) which can be placed in a jaw bone and comprising a structural part (4) associated with said post part, to which structural part a denture piece can be attached, the structural part comprising an integrally moulded contact pin (8) which can be placed in an associated shaped recess (10) in the post part (2) with a positive fit, it is to be possible on the one hand to suitably index the implant in a simple and reliable manner, on the other hand a particularly high level of mechanical stability against rotation being ensured, even with an overall height which is kept low. For this purpose, in accordance with the invention the cross-sections of the contact pin (8) integrally moulded on the structural part and of the shaped recess (10), associated with said contact pin, in the post part (2) each have a number of primary directions in which the radius in each case adopts a relative maximum value, the outer contour of the cross-section being selected in such a way that it is intersected at at most two points by any straight lines, and each point has only one tangent.

The invention relates to an adaptor system for a dental prosthesis. The adaptor system comprises an abutment and an adaptor, wherein said adaptor is adapted to connect to a prior art or new implants and is also connected to the abutment by a rotational connection. The adaptor and the abutment are secured to the implant by a screw that retains the angular position of the abutment.

A substantially tubular intermediate attachment part with a first through-hole for attaching a screw-retained dental prosthetic component or a dental tool to a dental implant or to a dental implant analog, extending along a first longitudinal axis between a first end and a second end. Each end is provided with a set of longitudinal fins intended for snap-fitting into the dental prosthetic component or into the dental tool on the one hand and into the dental implant on the other hand.

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 insert for connecting a dental implant to a dental abutment includes a dental abutment having at least two interfaces. A first interface of the at least two interfaces is formed in interaction with the abutment for fixing the dental insert to the implant by a latching and/or clamping connection. A second interface of the at least two interfaces is formed for fixing the dental insert to the dental abutment.

A method of using a dental filler is disclosed. The method may include securing a prosthetic to a dental implant, the prosthetic having an access channel therethrough. The method may also include filling a portion of the access channel by inserting a polytetrafluoroethylene dental plug into the access channel and compressing the polytetrafluoroethylene dental plug within the access channel.

A tooth implant system is provided, comprising a fixture, protrusions, and an abutment. The fixture has a top opening portion, a bottom closed portion, an inner surface portion, an outer surface portion, and a central hole portion surrounded by the inner surface portion. The plurality of protrusions are provided on the inner surface portion of the fixture at locations of substantially same heights from the bottom closed portion and with even circumferential intervals, and each of the plurality of protrusions comprises a vertical stop and a bottom edge. The abutment comprises an upper cylindrical portion, a middle connecting portion extending from the top cylindrical portion, and a lower engaging portion extending from the middle connecting portion. The lower engaging portion of the abutment is configured to be received into the central hole portion surrounded by the protrusions and engage with the protrusions.

The present invention relates to a prosthetic assembly (1, 10, 100) comprising a prosthetic component (2, 20, 200) and a retention screw (6, 60, 600) with an interference geometry (5, 50, 500) designed to allow relative rotation, limit relative longitudinal motion and inseparably join the prosthetic component (2, 20, 200) and the retention screw (6, 60, 600). The interference geometry (5, 50, 500) can be in the form of a ring attached to the retention screw (6) in a portion of the body of this screw (6) having a smaller diameter, or in the form of one or more inwardly folded flaps integrated in the prosthetic component (20) and diametrically distributed around the base thereof, or in the form of a uniform, tapered and hollow projection of the lower portion of the prosthetic element (200). The invention further relates to a method for producing the disclosed prosthetic assembly (1, 10, 100), including the following steps: forming a prosthetic component (2, 20, 200) having a central hole (8, 80) for receiving the retention screw (6, 60, 600), forming a retention screw (6, 60, 600), the body of which has a portion having a smaller diameter (62, 602), inserting the retention screw (6, 60, 600) into the central hole (8, 80) of the prosthetic component (2, 20, 200), and forming an interference geometry (5, 50, 500) between the base of the prosthetic component (2, 20, 200) and the body of the retention screw (6, 60, 600).
