A cementless type dental implant includes: an abutment having vertical slits spaced apart from each other around an upper portion thereof, and having elastic coupling protrusions disposed between the vertical slits and radially providing elasticity; a crown cap having a coupling portion formed at a lower portion therein so that the upper portion of the abutment is inserted therein, having a screw hole formed at an upper portion therein, having a coupling step formed at a center therein to couple the elastic coupling protrusions of the abutment, and having a crown integrally formed outside; and an abutment screw inserted and fastened in a screw insertion hole of the abutment and having a protrusion pressing portion formed at an upper end thereof and pushing the elastic coupling protrusions radially outward when being fastened such that the elastic coupling protrusions are coupled inside the coupling step of the crown cap.

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.

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.

A dental prosthesis implant which has an endosseous implant portion extending along an implant axis and a transgingival portion extending from the implant portion and forming an implant-prosthetic connection platform is provided. The implant-prosthesis connection platform extends perpendicularly with respect to a prosthetic axis, the prosthetic axis being inclined with respect to the implant axis. The transgingival portion forms a side wall with a diameter equal to or smaller than the diameter of the endosseous implant portion and progressively decreasing at least in a distal transgingival portion ending with the implant-prosthesis connection platform.

An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.

An abutment for a dental implant system includes a main body extending along a longitudinal axis from a first end to a second end. The main body includes a peripheral side surface having a continuously-flared profile from the first end to the second end. The abutment further includes one or more impression features formed at the second end of the main body and one or more scan features formed at the second end of the main body. A clocking element is formed at the first end of the main body. The abutment includes a matte material surface and is configured for use as an impression transfer and as a scan body in a dental implant operation.

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.

A zygomatic dental implant includes a generally cylindrical body, an interior threaded bore, and an asymmetrical external feature. The generally cylindrical body has a coronal portion and an apical portion. The generally cylindrical body has a main-central axis. The interior threaded bore is formed in the coronal portion of the generally cylindrical body for receiving a screw configured to removably hold an abutment in engagement with the zygomatic dental implant. The interior threaded bore has a bore-central axis. The asymmetrical external feature is on at least a portion of a first side of the generally cylindrical body such that the asymmetrical external feature is configured to directly engage alveolar bone of the patient. The asymmetrical external feature includes a plurality of circumferentially extending grooves.
