The present invention relates to endosseous implants and in particular, to screw form dental implants for implanting within bone. The bone implant is configured to be a self-drilling bone implant that is adept at condensing, collecting and distributing bone along all of the implant's surface and within the implantation site, to significantly increase the bone implant contact surface. The implant is configured to have a coronal portion and a body portion that are continuous with one another. The coronal portion is configured to have a smaller overall diameter than the overall diameter of said body portion. The body portion is fit with threading that facilitates the self-drilling and bone collection properties when the implant is rotates in both the clockwise and counterclockwise directions.

An apparatus includes a dental prosthetic, a metallic insert, and a plastic cap member. The insert is configured to be bonded in an interior of the dental prosthetic. The insert defines a passageway. The of the insert is configured to receive a screw. The cap member is configured to be interposed between the insert and the interior of the dental prosthetic.

An apparatus for replicating a tooth within a user's mouth includes a threaded insert receivable with a bore in a wearer's jaw, the threaded insert having a first connector associated therewith and a tooth implant having a second connector. The first and second connectors are frictionally engageable with each other to retain the tooth implant within the user's mouth.

A dental implant system including a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (L.sub.I) from an apical end (101) to a coronal end (102) and having an external surface for anchoring and osseointegrating in bone, a coronal end portion (105) having abutment connection geometry for cooperating with an abutment which can be seated in one or more defined positions on the implant, the abutment connection geometry having a coronally facing abutment contact surface (128) which extends around the full circumference of the implant, and in use directly contacts the abutment and provides a stop defining the axial location of the abutment relative to the implant, the coronal end portion further having a coronally facing prosthesis contact surface (129) located radially beyond the abutment contact surface, the prosthesis contact surface being a continuous surface extending around the full circumference of the implant.

The abutment contact surface of the analog has the same longitudinal cross-section and radial location relative to its longitudinal axis as at least a portion of the abutment contact surface of the implant about the entire circumference of the analog, such that the abutment contact surface of the analog matches at least a part of the abutment contact surface of the implant about its entire circumference, and the prosthesis contact surface of the analog has the same longitudinal cross-section and location relative to its abutment contact surface and longitudinal axis as one or more portion of the prosthesis contact surface of the implant, such that the prosthesis contact surface of the analog matches one or more part of the prosthesis contact surface of the implant. In comparison to the prosthesis contact surface of the implant, the prosthesis contact surface of the analog is discontinuous in at least the circumferential and/or radial direction.

A dental implant system including an implant, a prosthetics component, and a fastener. The implant and the prosthetics component are configured to assume a first taper connection and a second taper connection with one another. The implant has a male connection portion of the first taper connection. The prosthetics component is placed upon the implant and when the prosthetics component is not fastened to the implant by the fastener, a tolerance region is formed between the implant and the prosthetics component. The tolerance region is configured such that on fastening with the fastener, mating connection portions of the taper connections can be pushed further into one another.

The invention relates to a dental prosthesis production device and method of manufacturing a dental prosthesis in which the dental prosthesis has an implant (40) and an abutment (10) which has a shape that is compatible with the implant (40) and on or to which abutment a dental structure (28) that is made of a dental material, in particular ceramic and/or plastic, and produced with the aid of a CAM process using rapid prototyping or compression molding technology can be secured. The abutment is mounted on the implant (40) via a releasable connection, in particular a screw connection (44), having an anti-rotation mechanism (50), and an anti-rotation device (groove 22) is formed between the abutment (10) and the dental structure (28). A selection device (66) is provided for abutments, said selection device allowing a selection of the abutment (10) for producing the dental prosthesis, optionally after reducing the abutment height to a specified value in a patient-specific manner, and a machining tool, in particular a milling cutter, or a CAM device is provided for shortening the abutment (10).

A two part modelling aid (1, 100) for connection to a dental implant component (200), the modelling aid comprising a hollow base part (10, 110) comprising an open apical end (14, 114), an open coronal end (16, 116) and a tubular side wall (12, 112) extending from the apical to coronal end along a linear longitudinal axis (L.sub.B), the side wall having an interior and an exterior surface, one of said surfaces comprising an anti-rotation section (18, 118) having a non-circular symmetric cross-section in a plane perpendicular to the longitudinal axis, and a hollow angled part (30, 30) comprising an open apical end (34, 134), an open coronal end (36, 136) and a tubular side wall (32, 132) extending between the apical end and coronal end and having an interior and exterior surface, the tubular side wall forming an apical portion (35, 135) of the angled part extending along a first linear axis (L.sub.1), and a coronal portion (37, 137) of the angled part extending along a second axis, the second axis being non-coaxial to the first axis such that the tubular sidewall creates a non-linear channel (38, 138), the apical portion being sized and shaped to form a friction fit with the base part, wherein, when the base part is connected to the angled part, a closed channel (60, 160) is formed extending from the apical end of the base part to the coronal end of the angled part, the first axis of the apical portion of the angled part being coaxial to the longitudinal axis of the base part and the anti-rotation section of the base part being exposed on a surface of the base part.

The present invention relates to: a break-resistant reinforced implant structure which manufactures a fixture and an abutment by a ceramic material having excellent strength and biocompatibility, and reinforcing a preset position into which friction is concentrated during internal and external shock or mutual bond procedure by a predetermined metal to prevent damage in order to compensate for a disadvantage of a ceramic worried about damage due to lack of elasticity; and a method of manufacturing the break-resistant reinforced implant structure. The break-resistant reinforced implant structure comprises: a fixture (10) and an abutment (20) which are formed by a ceramic material integrally or integrally by mutual coupling as individual split type. The fixture (10) and the abutment (20) are stacked therein with a reinforced layer (30) at surfaces or mutual coupling surfaces.

The cavity zones (67, 62) of the implant post (23, 150, 160, 170, 180, 190) and of the implant pin (50) transition into each other. The center lines (69, 63) include an angle of 60 to 86 angular degrees. An attachment element (5) can be arranged on the implant post (23, 150, 160, 170, 180, 190) in a rotationally fixed manner by means of an assembly joint (140), which forms an interface (141, 145). The attachment element (5) is a cap-type element. At least some areas of the implant flange (31) have a supporting enveloping surface (37). The attachment element (5) has an interface geometry (146), which can be mounted on the interface geometry (142) of the superstructure support (20) in an interlocking and/or frictional manner at least in some areas. By means of the invention, a superstructure support (20) for the prosthetic tooth replacement is improved in such a way that the interface between the implant post (23, 150, 160, 170, 180, 190) and the attachment element (5) enables secure and simple joining and disconnecting of the interface components.
