A dental implant system including a dental implant (1) and an associated implant analog (50), the implant extending along a longitudinal axis (L1) 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 invention relates to an implant for osseointegration into a jaw bone, having a receiving opening one section of which is designed as an inner polygon, and at its distal end, the implant includes an indexing that reproduces the geometry of the inner polygon.

The invention relates to a superstructure support (20) as part of a prosthetic tooth replacement (1) between an implant body (10) and a superstructure, comprising a hollow implant post (23), a hollow implant pin (50), and an implant flange (31) lying therebetween. The cavity zones (67, 62) of the implant post (23) and of the implant pin (50) transition into each other. The cavity zones have respective center lines (69, 63), which include an angle of 60 to 86 angular degrees. The cavity zone (62) of the implant pin (50) has a screw head seat surface (65) that widens toward the implant flange. At least some areas of the implant flange form a supporting enveloping surface (37), which is oriented toward the implant post (23) and the outer edge (33) of which spans a reference plane (38), which is perpendicularly intersected by the center line (69) of the post-side cavity zone (67). The center lines of the implant post (23) and of the implant pin (50) intersect or cross below the reference plane (38). By means of the invention, a superstructure support (20) for the prosthetic tooth replacement is improved in such a way that a secure and lasting screwed connection to the implant body is ensured.

A dental implant includes a generally cylindrical body, an interior bore, and a non-rotational feature. The generally cylindrical body has a main-central axis and is formed from cold-worked, high strength, commercially pure titanium having an ultimate tensile strength of at least about 900 MPa. The generally cylindrical body has a proximal portion and an opposing distal portion for anchoring the dental implant in bone of a patient. The interior bore is formed in the generally cylindrical body and has (i) a bore-central axis and (ii) a threaded portion for receiving a screw that is configured to removable hold an abutment in engagement with the dental implant. The non-rotational feature is configured to engage the abutment in a non-rotational fashion.

A multi-piece dental prosthesis system is provided. The system includes an implant which can be implanted into a bone of the patient, an abutment removably connected to the implant by a prosthetic screw, and a ti-base removably connected to the abutment. The system may be used to hold a crown, denture, or partial denture in place.

An anatomically-contoured subperiosteal jaw implant includes an annular-shaped baseplate and internal support arms corresponding to a location of a plurality of height-adjustable posts. The baseplate is configured for placement over the alveolar ridge of a mandible or maxilla bone and creates a plurality of internal apertures within the baseplate to minimize the impact on the alveolar ridge and improve re-attachment of bone and soft tissue revascularization after implant insertion. The baseplate is attached with the bone via a series of screws inserted through screw holes uniquely positioned throughout the baseplate based on individual anatomical models of a patient receiving the implant, and the height-adjustable posts are also shaped for partial insertion into the bone to reduce the height of the posts and attached dental component while also improving retention of the implant. The support arms absorb stress on the posts received via a chewing or grinding action of the jaw.

The present invention relates to a connection between a post part provided for being screwed into the jawbone and an associated superstructure part to which a dental prosthesis can be fastened. The connection between the post part and the superstructure part has a rotational self-centering action, wherein at least one of the surfaces provided for this purpose has a friction-minimizing modification and/or coating.

The invention relates to an abutment for use in a dental implant system, wherein the abutment is provided with a guiding and lock for associating the abutment to a dental implant, the guiding and lock including: a first conically tapered section; a second substantially non-tapered section arranged apically adjacent to the first section, the second section being provided with an anti-rotational means; and a third substantially circular cylindrical section arranged apically adjacent to the second section, such that to provide axial guiding to the abutment upon the insertion thereof into a dental implant. Further, the invention relates to a dental implant formed in a similar manner.

An abutment for use in combination with a dental prosthesis and a dental implant configured for implantation in an osseous structure is provided. The abutment comprises an abutment wall comprising a flexural region comprising a shoulder portion and an abutment recess located below the shoulder portion when the abutment is in an upright position. The flexural region is configured to enable at least a vertical movement of an upper portion of the abutment relative to a lower portion of the abutment when the abutment is subjected to a loading force. There is also provided a retention assembly comprising a first member and a second member each positionable within a longitudinally extending abutment channel of an abutment in a spaced apart relationship to define an abutment chamber therebetween. A method for implanting a dental implant assembly into a mouth of a patient is also provided.

A dental assembly includes a prosthesis having a base and a plurality of artificial teeth, and at least one connecting element coupled to the prosthesis and configured to facilitate coupling of the dental assembly to a patient's oral cavity. The at least one connecting element includes a cylinder with a body having a first end, a second end, and a passageway extending between the first and second ends. The connecting element further includes an opening through a sidewall of the cylinder that is open to the passageway. The slot allows access to a fixation screw positioned in the cylinder from a direction that is angled relative to an axis of the cylinder. A method of making a dental assembly is also disclosed.
