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 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.

Dental screw which can be inserted into a cavity of a patient's maxillary and/or mandibular bone, including a terminal portion that can be inserted into the cavity so as to fit within it and so as to engage a side wall thereof. The dental screw further includes a cervical portion, configured to engage an artificial tooth structure, and a central portion extending longitudinally between the terminal portion and the cervical portion. The central portion is shaped as a porous structure, particularly as a trabecular structure, to promote an intraosseous regrowth process. The dental screw is further characterised in that the terminal portion, the central portion and the cervical portion are made from a single piece.

A system, device and method for restoring the use of a damaged dental implant. The system, device and method utilizes a dual thread fixation screw capable of coupling an abutment or abutment assembly to the damaged dental implant, therein rescuing the damaged dental implant.

A dental implant system can include an upper implant body coupled to a lower body with a cavity between the upper and lower implant bodies. The system can further include an anchor at least partially disposed within the cavity. The system can also include an abutment that couples to the anchor and serves as a mounting area for a crown. The anchor can be rotatable and swivelable, allowing the lower implant body to be implanted at an angle in bone while permitting the crown to be positioned in a natural tooth orientation.

A dental device and a method of use for associating with an implanted dental implant anchor immediately following implantation. The device provides for projecting the implant's location, orientation and axis such that the device is readily visible to the naked eye by way of visual inspection so as to reveal the location of the implanted dental implant anchor following a healing period. The device having a distal portion, for coupling to the dental implant, a medial portion, for covering the proximal end of the dental implant, and a proximal portion, defining a vertically adjustable shaft provided for projecting the location, orientation and axis of implant anchor.

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 novel screw-fastening assembly having anti-loosening capabilities includes a first and a second screw elements 11,12 adapted to be screw-fastened; the element 12 includes a recess R, the recess being open toward the element 11; and the element 11 includes an protrusion P, the protrusion being introduced into the recess R in a fastened state. The recess R has an inner peripheral surface formed in a cylindrical shape that is straight along the axial direction. The protrusion P is shaped as a circular column or cylinder having a maximum-diameter portion at one location along the axial direction. The protrusion P and the recess R are eccentric relative to each other such that the maximum-diameter portion of the protrusion and the inner peripheral surface of the recess are in pressure contact only along part of their circumference in the fastened state. The maximum-diameter portion is spaced apart from the base end of the protrusion P by a predetermined distance so as to allow the protrusion to move forward and backward along the axial direction relative to the recess R with the maximum-diameter portion being in pressure contact with the inner peripheral surface of the recess R only along part of their circumference.

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 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.
