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.

An implant includes an elongated and cylindrical body; conical apical region coated by a screw thread and with at least three helical chambers and semi-spherical end; and a cervical region defined by a smooth cervical surface. The elongated and cylindrical body includes at least one longitudinal strip having a substantially smooth surface. The smooth longitudinal strip is located in the zygomatic implant cervical portion. The connection between the screw threads and the smooth longitudinal strip is made by a transition curvature, and the smooth longitudinal strip is aligned with one of the flat sides of the internal area with hexagonal cross section of the implant prosthetic interface.

A dental implant having an anchoring system consisting of foldable fins actuated by an insertion screw; the dental implant is characterised by the following components: an implant body that includes an implant-abutment connection zone, an externally threaded zone, at least one pair of exit openings and an internally threaded zone; an anchoring having at least one pair of foldable fins and a top opening; an insertion screw having a head with an internal hexagonal socket, a stem and a screw thread; when the insertion screw is screwed into the top opening of the anchoring means, the insertion screw pushes the anchoring down into the implant body and causes the foldable fins to extend outwards through the exit openings.

Dental implant assembly comprising an implant with a body having an outer implant surface configured for osseointegration and a connection well, and an abutment comprising a prosthesis mounting portion for assembly of a dental prosthesis thereon and a connector mounting cavity. The assembly further comprises a connector comprising an implant mounting portion for assembly in the connection well of the implant, and an abutment mounting portion for assembly in the connector mounting cavity of the abutment, the abutment mounting portion of the connector comprising an index portion and the abutment connector mounting cavity further comprising an index cavity portion for receiving the index portion therein, the index portions configured to register the rotational orientation of the abutment about a longitudinal axis (A) with respect to the connector.

The present invention has the purpose of forming a new implantodontic system with spherical components, applied to implantology, particularly in fixed and mobile prostheses, aiming not to allow the accumulation of microorganisms that develop peri-implantitis and not compromising the osseointegration of the implant, produced in titanium metal and/or surgical stainless steel, which together form this new dental system with excellent locking and reduction in the retention of microorganisms, improving asepsis and making the development of infections extremely unlikely; consisting of implant (1) or spherical intermediates CM (10) or HE (14) or HI (17) and UCLA (8), bringing advantages of greater prosthesis angle from 0° to 45°, versatility, rigidity in the set, torque and resistance mechanics of the forces existing during chewing.

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.

Dental implants may be designed using a three-dimensional scan of an extracted tooth root and/or a corresponding socket site. The dental implant may include three portions: a root portion designed to sit below the patient's gum line, a connector portion positioned above the root portion and designed to sit above the gum line, and an abutment portion positioned above the connector portion upon which a temporary or permanent crown may be placed. The root portion may include three sections that correspond to three areas of a three-dimensional scan of an extracted tooth root. The first and third sections of the implant may have a size and shape that corresponds to a first and third portions of the three-dimensional scan, respectively. A circumference of the second section of the implant may be smaller than a corresponding circumference of the second section of the three-dimensional scan of the tooth root.

A convertible dental assembly is disclosed herein. The convertible dental assembly includes abutments adapted for fixing with implants; fixed-hybrid housings adapted for fixing with the abutments through a fixing screw; and removable-hybrid housings, adapted for engagement with abutments through snap fit parts. The fixing screw and the snap fit part are fixed to the abutments through same female threads on the abutments. The fixed-hybrid housings are used for a fixed-hybrid dental assembly during period of healing of the implants, and replaced by the plurality of removable-hybrid housings along with the snap fit parts for a removable-hybrid dental assembly after the period of healing of the implants. The fixed-hybrid housings and the removable-hybrid housings can be captured in the dental assembly via chair-side pickup at respective instances. The removable-hybrid housings can be placed indirectly by a dental laboratory if a new denture is being fabricated. The abutment includes an outer frustoconical profile that engages with matching frustoconical cavities in the fixed-hybrid housings and removable-hybrid housings.

The present invention relates to a prosthetic assembly (1, 10, 100) comprising a prosthetic component (2, 20, 200) and a retention screw (6, 60, 600) with an interference geometry (5, 50, 500) designed to allow relative rotation, limit relative longitudinal motion and inseparably join the prosthetic component (2, 20, 200) and the retention screw (6, 60, 600). The interference geometry (5, 50, 500) can be in the form of a ring attached to the retention screw (6) in a portion of the body of this screw (6) having a smaller diameter, or in the form of one or more inwardly folded flaps integrated in the prosthetic component (20) and diametrically distributed around the base thereof, or in the form of a uniform, tapered and hollow projection of the lower portion of the prosthetic element (200). The invention further relates to a method for producing the disclosed prosthetic assembly (1, 10, 100), including the following steps: forming a prosthetic component (2, 20, 200) having a central hole (8, 80) for receiving the retention screw (6, 60, 600), forming a retention screw (6, 60, 600), the body of which has a portion having a smaller diameter (62, 602), inserting the retention screw (6, 60, 600) into the central hole (8, 80) of the prosthetic component (2, 20, 200), and forming an interference geometry (5, 50, 500) between the base of the prosthetic component (2, 20, 200) and the body of the retention screw (6, 60, 600).

Dental implants, dental abutments, and dental systems are disclosed. A dental implant can include an implant body having a longitudinal axis, a coronal end, and an apical end. An internal bore can be provided within the implant body, and can have a coronal end, adjacent to the coronal end of the implant body, and an apical end. The internal bore can include a first internally facing surface, extending from the coronal end of the internal bore towards the apical end of the internal bore, at least a portion of which tapers inwardly towards the apical end of the internal bore. The internal bore can further include an internally threaded portion positioned between an apical end of the first internally facing surface and the apical end of the internal bore. A dental abutment can be configured to engage with the dental implant.
