The present invention is related to a dental implant comprising at least a lower part and at least an upper part; wherein said lower part of the dental im-plant, which is adapted to be connected to the jawbone of a patient, is made of an at least first material; wherein said upper part of the dental implant, which is adapted to be connected to the lower part of the dental implant, is made of an at least second material; and wherein the upper surface of the upper part of the dental implant is adapted to be aligned with the upper surface of the jawbone of a patient; wherein said at least first material is different from said at least second material; wherein the at least second material of the upper part of the implant is made of a ceramic material, and wherein said ceramic material comprises zirco-nium dioxide comprising at least one coloring additive. The present invention is further related to a dental restoration system com-prising at least such an inventive dental implant and at least an abutment, wherein the abutment is adapted to be connected to the dental implant, and wherein the abutment is made of at least a third material; wherein the abutment is made of a ceramic material, and wherein said ceramic material comprises zirconium dioxide comprising at least one coloring additive.

A dental implant includes a fixture implanted into an alveolar bone, an abutment fixed to an upper part of the fixture and having a core hole formed in a center of an upper surface of the abutment, a crown bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown, and a cover screw having a screw screw-fastened to the core hole and a head in close contact between an upper surface of the abutment and a lower surface of the crow to cover the core hole, in which, when the screw is released by a tool passing through the passage, the head moves up so that the cover screw provides a separating force to the crown. The dental implant may facilitate a separation of the crown and prevent binding force from weakening, thereby enabling an efficient procedure and management.

A dental implant includes an insert element of a titanium-based material inserted and soldered into a blind hole in an anchoring element of a ceramic. The insert element has spacer members to center it in the blind hole, with a uniform circumferential gap space relative to the anchoring element. A portion of the insert element protrudes outwardly beyond an end face of the anchoring element. The blind hole is partly filled with a glass solder, and the insert element is inserted into the blind hole, whereby some of the glass solder is displaced out of the gap space onto the end face of the anchoring element and the protruding portion of the insert element. A thermal soldering process secures the insert element into the anchoring element. The protruding portion of the insert element and remaining excess solder are removed to form a planar surface.

A bone coupling device is configured for joining a first bone piece to a second bone piece which includes a first component having an inner surface bounding a first cavity and a first stem portion for insertion into the first bone piece. A second component includes a second stem portion for insertion into the second bone piece and an axially extending connector extending from the second stem portion and configured to be inserted into the first cavity. The connector has an outer surface which is complementarily shaped relative to an inner surface to inhibit rotation relative to each other when the connector is received in the cavity to engage the first component and the second component.

A dental device comprises: a dental implant comprising a core enveloped by an expandable anchor comprising a plurality of joined segments. Prior to insertion of the core into the expandable anchor a carrier apically displaces within the expandable anchor, generating an expansion force causing the plurality of joined segments to be displaced linearly away from the central axis of the implant where the coronal and apical ends of each joined segment are displaced in parallel paths normal to the central axis of the implant. The core inserts into the expandable anchor to lock the plurality of joined segments in their expanded configuration. At least a first rail on the core is received by a corresponding expandable anchor slot to align the core and expandable anchor and at least a first core and expandable locking lodge engage to lock the core into the expandable anchor.

The present Utility Model refers to a new functional perspective applied to the prosthetic component called “SCREWED ANGLED TRUNNION” developed in light of the need to enable screw-fastening of dental prostheses be they unitary or multiple; characterized by applying an inner thread in its upper part, which may be made of grade 1, 2, 4, and 5 titanium or else made of any other material as may be used in the creation of dental prosthesis components, whereby enabling a further choice in the form of coupling the implant fixed thereto, and may be manufactured for CM, EH and IH fittings or any other fitting forms as may be developed, promoting and facilitating the maintenance process thereof in view of the possibility of threading, contributing to reduce the build-up of residues and consequently reducing the possibility of inflammation at the base of the implants.

An implant abutment is disclosed. An implant abutment for connecting a fixture and an artificial prosthesis, according to one embodiment of the present invention, comprises: an abutment lower part coupled to the fixture; an abutment upper part coupled to the artificial prosthesis, wherein the abutment lower part and the abutment upper part are integrally formed or separately coupled; and a small-movement part, which is interposed between the abutment upper part and the abutment lower part or disposed on a portion or all of the abutment upper part.

A patient-specific dental implant abutment may comprise an abutment base that attaches to a dental implant, the abutment base comprising a base top, a base bottom, and a base side, the base side continuously connecting the base top and base bottom together, the abutment base constructed to removably attach to a dental implant. The device may further comprise a set of abutment caps, each abutment cap comprising a cap top connected to the cap bottom, the cap bottom removably attaching to the top of an abutment base in a manner that the cap top does not contact an emergent sulcus, wherein each abutment cap has a different cap top that is constructed to handle at least one function relating to a phase of a dental implant surgery.

A dental implant includes a fixture implanted into an alveolar bone, an abutment fixed to an upper part of the fixture and having a core hole formed in a center of an upper surface of the abutment, a crown bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown, and a cover screw having a screw screw-fastened to the core hole and a head in close contact between an upper surface of the abutment and a lower surface of the crow to cover the core hole, in which, when the screw is released by a tool passing through the passage, the head moves up so that the cover screw provides a separating force to the crown. The dental implant may facilitate a separation of the crown and prevent binding force from weakening, thereby enabling an efficient procedure and management.
