Device including implant type support defining constraint axis, connector operatively interconnecting the support and dental prosthesis along the constraint axis, defining a constraint configuration having firmly constrained support and prosthesis, and a graft including first portion extending mainly parallel to constraint axis, a body including guide extending along transverse or slanted direction relative to constraint axis and cavity extending parallel to constraint axis for housing the first portion when connector is in the constraint configuration, obstructer including slider compliantly housed within the guide. First portion including a hole substantially aligned with the guide, when the connector is in constraint configuration, to allow insertion of slider into hole, and the obstructer for achieving a force magnetic on the slider for moving the slider along the guide so at least part of the slider enters hole, when the connector realizes the constraint configuration, to obstruct reciprocal movement between graft and body.

The invention relates to an anchoring device (1) for implant-supported removable dental prostheses having a female anchoring part (2); having a male anchoring part (3) connected to the female anchoring part (2); and having a base (4) that comprises a connection geometry arrangement (4A) and an implant thread (4B) for fastening the anchoring device (1) in an implant (6), characterized in that the male anchoring part (3) and the base (4) are interconnected by an elastic connection element (5).

A feature for retaining a denture on dental implants is shown and described. An anchor for receiving prongs is threaded to each of one or more implants in the mouth. A denture having prong passages is placed onto jaw bone or overlying tissue, above the implant. The anchor occupies an opening in the denture. With the denture in place and with the prong passages aligned with prong reception sites of the anchor, a pronged denture connector is installed such that the prongs pass through the prong passages of the denture and penetrate the prong reception sites of the anchor. The prongs are frictionally secured in place by an elastic member lining the prong passages of the denture and constricting over inserted prongs. Optionally, the elastic members include a bridge securing one elastic member parallel to the other. The denture may comprise synthetic resin reinforced by a metallic reinforcing bar.

Dental device including a base defining a main axis and including first and second portions, one configured to be constrained on a user's osseous portion, the other to be constrained to one or more artificial teeth, constraint element a constraint configuration wherein the first and the second portions are mutually constrained and a rest configuration wherein the first and second portions are separable. The constraint element including one wedge slider movable along the main axis to determine rest and the constraint configurations. A movable element at least partially counter-shaped to the slider and expandible radially relative to the main axis. An obstacle to interfere with the movable element when the constraint element is in constraint configuration to block mutual translation of the portions along the main axis. The cursor and the movable element arranged on the first portion. The obstacle is arranged on the second portion.

A denture retaining system and a denture bar constructed to be affixed in a human mouth, the denture bar including a distal end, lingual-side surface, vestibular-side surface, bone-facing surface and superstructure-facing surface opposite the bone-facing surface. The bone-facing surface at the distal end is relieved from the superstructure-facing surface at the distal end by an angle of between 10 and 25 relative to an axis perpendicular to a longitudinal plane passing through the lingual side and vestibular side surfaces of the denture bar. The system also includes an overdenture superstructure having a distal surface that substantially conformingly mates to the denture bar distal end when the overdenture superstructure is positioned against the denture bar superstructure-facing surface, and is coupled to the denture bar by at least one attachment element located at a position to an anterior side of a first molar position.

A cradle, assembly, system, and method for installing a prosthesis at a surgical site. The cradle temporarily engages the prosthesis and holds it in the correct orientation and position adjacent the surgical site. An aperture is defined in the cradle and a portion of the prosthesis is received therein. In one embodiment, the cradle, assembly and system are used to install a final dental prosthesis in a patient's mouth in a single visit to the dentist's office. A securement member pins the surgical template and subsequently the cradle to the jaw. A metal sub-structure on the final dental prosthesis is received in the aperture in the cradle. Cylinders attached to implants anchored in the jaw extend through holes in the sub-structure and are bonded to the prosthesis. The cradle is detached from the jaw and from the prosthesis prior to screws being re-inserted through the cylinders and into the implants.
