A dental prosthesis (100) for anchoring in the jawbone (1), comprising a dental implant (110) with an implant body (111) and an abutment (112), a tooth part (120) with an internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120), and a closure body (130) for sealing the dental prosthesis (100) within the internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120). A connecting sleeve (140) is arranged between the closure body (130) and the internal guide (122) of the tooth part (120), by means of which connecting sleeve the tooth part (120) and the dental implant (110) can be connected to one another indirectly, detachably and/or by means of which connecting sleeve the closure body (130) can be releasably locked within the internal guide (122) in the tooth part (120), in particular penetrating the tooth part (120).

A tool assembly for mounting a dental abutment includes a first tool, the first tool having an axis of elongation, a first end configured to engage, in use, the abutment, and a second end, where a first portion of the first tool at or near the first end has a peripheral wall and, opposite the wall, a first opening extending along all or part of the first portion, a second opening open in an axial direction is disposed at the first end, the tool assembly further including a second tool configured to releasably engage a fixing element, where a contiguous space is defined between the first opening and the second opening whereby, in use, the fixing element, or the fixing element attached to the second tool, may pass through the first opening and the second opening to permit secure fixing of the abutment to an implant or frame using the second tool.

A denture abutment retention apparatus and a denture including one or more denture abutment retention apparatuses configured to allow the denture to be easily engaged with and secured to a plurality of denture abutments in a user's mouth using sliding motion of the denture from the sides of the plurality of denture abutments.

An assembly for dental restoration includes a healing element able to be connected to a dental implant, the healing element including a lateral surface intended to be integrated within a gum for the purpose of shaping the gum as the gum heals, and an end surface that forms, together with part of the lateral surface, an emergent surface that is intended to remain outside the gum and is asymmetrical with respect to at least one perpendicular median plane. The assembly for dental restoration also includes a detachable prosthesis support having a receiving part for a crown prosthesis and a linking part capable of engaging with a matching linking zone that is defined in a through-opening that is provided in the healing element.

A dental prosthesis system includes a dental implant having a dental implant fixture and an internal locking collar extending upwardly from the dental implant fixture. The internal locking collar defines a central bore extending downwardly into the dental implant fixture. An abutment for cement has a base surface for placement against the dental implant, which defines a central hole aligned with the central bore. A securing mechanism secures the abutment for cement to the dental implant. The securing mechanism including an expansion locking system disposed through the central hole and within the bore. A portion of the expansion locking system is expandable outwardly so as to lock the abutment for cement to the dental implant fixture.

A set of components for dental prosthetic restoration includes a ceramic dental implant having an internal connecting receiving space. An internally threaded insert is added into the internal connecting receiving space of the dental implant, and rotatably indexed. It is held by a fixing part forming an axial abutment opposing an extraction of the internally threaded insert out of the inner connection receiving space.

A combined assembly for dental prosthesis is provided, wherein the combined assembly includes a first joint member and a second joint member. The first joint member has a first body and a plurality of elastic hooks, and the elastic hooks are annularly arranged to connect one end of the first body, wherein a slot is disposed between the adjacent elastic hooks, and each of the hook has a top portion protruding outward. The second joint member has a second body, and the second body is provided with a joint hole, a side wall surface of which is provided with a ring groove, wherein the elastic hooks extend into the joint holes, and the top portions of the elastic hooks engage into the ring groove.

A dental implant is provided, wherein the dental implant includes a dental root implant. The dental root implant forms a columnar body, and two ends thereof have a tubular portion and a joint portion, respectively, wherein the tubular portion is provided with a plurality of through holes. A central groove is formed inside the tubular portion and communicates with the through holes, wherein an inner diameter of the central groove tapers from approaching the joint portion to away from the joint portion. The joint portion can be coupled to a dental crown, and the tubular portion can be coupled to a human alveolar bone. The through holes can facilitate an osseointegration of the dental root implant in the alveolar bone.

A device and a system for forming a releasable connection between a dental implant abutment and prosthetic restoration, and in particular to such a device and system that is configured for use in situations where the inter-occlusal space is very limited, the device having a female connection device having a hollow tubular body featuring an open lumen.

An approach for attaching a superstructure, such as a crown, to an abutment by an approach that includes causing thermoplastic material to become flowable due to mechanical energy input, and to flow relative to an attachment structure to secure the superstructure and crown together.
