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.

The present invention relates to a dental implant and a replacement ring. The dental implant has an insertion portion for anchoring in a jaw bone. The replacement ring serves for replacing a subtractively removable annular material region in a coronal region of the insertion portion. The shape of the replacement ring is inscribable into the shape of the dental implant in the coronal region at least to some extent such that an inner lateral surface of the replacement ring lies within the shape of the dental implant.

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.

Dental implant comprising an implant body having on an outer side an external thread for fastening the dental implant to a jaw bone and having an opening extending along a longitudinal axis of the dental implant. The opening comprises an internal thread for fastening a superstructure to the dental implant. The implant body further comprises an interface for fastening the superstructure to the dental implant, which interface is arranged at a front end of the implant body. The dental implant further comprises an anti-rotation element which is configured to prevent rotation of the superstructure around the longitudinal axis relative to the dental implant, wherein the anti-rotation element is configured as a component separate from the implant body, which is attached to the implant body in an area of the interface.

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 restoration system is disclosed. A dental restoration system includes an implant, retention component, dental component and driver tool. The retention component is sealable in a retention chamber of the implant. The retention component includes a driver section for interfacing with a driving head of the driver tool and a dental component engagement section with a threaded surface. The dental component includes a retention component interface surface with threads. The dental component engages the retention component via the threaded surface interlocking with the threads of the retention component interface surface when the dental component is inserted in the implant. The driver tool is used to rotate the retention component to engage the dental component apically. The retention component contacts the retention component wall and the dental component contacts an annular shoulder of the implant when the dental component is fully attached to the implant.

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.

A dental abutment system including an abutment, an inlay and screw, wherein the screw at least partially occupies the interior channel of the inlay. A method of manufacturing a dental abutment system and to a control data set including a plurality of control instructions that are configured to, when implemented in an additive manufacturing system, to cause the system to execute at least the step of forming an abutment at the distal end of an inlay using an additive manufacturing process. The screw is a captive screw. The interior channel of the abutment is variable in diameter and the smallest diameter is ≥102% and ≤110% of the width of the screw head and the longitudinal axis of the interior channel of the abutment and the longitudinal axis of the interior channel of the inlay are angled with respect to each other at an angle of ≥5 degrees.

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.

Disclosed herein is a dental implant (1) having a post part (2) which can be placed in a jaw bone and having a structural part (4) associated with said post part, to which structural part a denture piece can be attached, the structural part comprising an integrally molded contact pin (8) which can be placed in an associated shaped recess (10) in the post part (2) with a positive fit, it is to be possible on the one hand to suitably index the implant in a simple and reliable manner, on the other hand a particularly high level of mechanical stability against rotation being ensured, even with an overall height which is kept low.
