A system assembly interface between a multi-part superstructure carrier, which carries a superstructure, and an implant body, which has an internal thread, is disclosed. A part of the superstructure carrier is arranged on the implant body via an implant screw bolt. The superstructure carrier comprises a superstructure main carrier and an attachment carrier that is detachably screwed to it. The system assembly interface ensures secure support of the superstructure with simple pre-assembly and final assembly. In the case of a plurality of implant bodies carrying a partial or total prosthesis, no appreciable stresses occur despite static overdetermination.

Disclosed herein a fixture engagement structure which constitutes a dental implant assembly and engages with a fixture inserted into a jawbone. The fixture engagement structure comprises: a first engagement structure alignment portion that is placed radially in an engagement area portion engaging with the fixture; and at least one second engagement structure alignment portion that is placed radially in the engagement area portion so as to be separate from the first engagement structure alignment portion and is arranged asymmetrically with respect to a center point located on a central axis of the fixture engagement structure. The second engagement structure alignment portion has a larger size than the first engagement structure alignment portion, along at least one of an outer circumference direction and a radial direction of the engagement area portion.

An implant abutment capable of stably adjusting vertical dimension of occlusion, the implant abutment comprising: an upper coupling portion that is an upper portion coupled to an artificial tooth; a lower coupling portion that is a lower portion coupled to a fixture; an exposed portion that is a portion exposed to the outside between the upper coupling portion and the lower coupling portion, and an adjustment groove that is formed on an outer circumferential surface of the upper coupling portion and inwardly recessed in the upper coupling portion. According to the implant abutment capable of stably adjusting vertical dimension of occlusion of the present invention, although the abutment has a low upper coupling portion, it can maintain stable coupling with the artificial tooth, thereby ultimately ensuring ease of adjusting a height of the abutment.

Dental implant and superstructure each with an interface that allows direct attachment of the superstructure to the dental implant without the use of an abutment. The dental implant comprises an anti-rotation element that is arranged in the opening and is configured to prevent the superstructure from rotating about a longitudinal axis relative to the dental implant. The superstructure comprises an interface corresponding to the anti-rotation element, having a recess with two mutually opposite side flanks which are at a first distance from each other in a first region and, in a second region which is at a greater distance from the longitudinal axis than the first region, are at a second distance from each other, the second distance being smaller than the first distance.

A two part modelling aid for connection to a dental implant component including a hollow base part and a hollow angled part, each including a tubular side wall extending between apical and coronal ends. The base part side wall includes an anti-rotation section including a non-circular symmetric cross-section in a plane perpendicular to a longitudinal axis of the base part. The angled part side wall forms an apical portion that extends along a first axis and is sized and shaped to form a friction fit with the base part, and a coronal portion extending along a second axis non-coaxial to the first axis. When connected, a closed channel is formed extending from the base part to the angled part, and the first axis of the apical portion is coaxial to the longitudinal axis of the base part and the anti-rotation section is exposed on a base part surface.

An implant abutment according to the present invention is a dental implant abutment with an enhanced shock distribution function, the dental implant abutment comprising: an upper coupling portion that is an upper portion coupled to an artificial tooth; a lower coupling portion that is a lower portion coupled to a fixture, and an exposed portion that is exposed to the outside between the upper coupling portion and the lower coupling portion and has a plurality of flow grooves. By forming a plurality of grooves in the exposed portion of the implant abutment, the exposed portion of the implant abutment performs a shock distribution function as if it shakes elastically and distributes an occlusal force of teeth exerted to the implant, thereby providing a buffering function of relieving an impact on an area where the implant is inserted.

An abutment for use with a dental implant. The abutment includes a connecting pin configured to be introduced into an associated receiving channel of the dental implant. The connecting pin includes a screw channel for a connecting screw for connecting the abutment to the dental implant. An inner diameter of the screw channel over its entire length up to an opening on an end face is at least as large as the diameter of a screw head of the connecting screw, and a plastically deformed retaining element is provided in order to support the connecting screw.

The disclosure relates to methods for attaching a dental implant surgical guide and a dental implant to a dental surgical site including: assembling an implant combination, positioning the dental implant surgical guide including a double open-ended guide cylinder at the dental surgical site; rotating the implant combination through the double open-ended guide channel; and attaching a cap comprising a hollow cylinder to the double open-ended guide channel so the rim of the implant mount body is sandwiched between the dental surgical guide and the cap. The disclosure further relates to a dental prosthesis apparatus including: an abutment; a dental implant; a dental implant surgical guide including a first and a second double open-ended guide cylinder connected by a support bar; an implant mount including a rim; and a cap operable to engage the dental implant surgical guide and sandwich the rim between the cap and the dental implant surgical guide.

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.

The present invention relates to an anchoring system for attaching a prosthesis to a human body, comprising: an anchoring element, an abutment, an abutment screw for attaching the abutment to the anchoring element, the anchoring element comprises a connection area for the abutment, the connection area comprising a press-fit portion such that the abutment is attached to the anchoring element in the connection area by a press-fit connection, wherein the connection area comprises an anti-rotation geometry and the abutment comprising a corresponding mating anti-rotation geometry proximal to the press-fit portion, and where in the connection area comprises a conical portion proximal to the anti-rotational geometry forming a mating geometry for a corresponding conical portion in the through-hole of the abutment.
