The invention relates to a screw, a tool and a system for dental implantology, forming a fixing system and the components thereof to be used in a dynamic pillar assembly. Said dynamic pillar assembly is used in the production of prostheses on dental implants in human implantology in order to fix screws at an angle.

A dental implant, including a generally cylindrical body having a proximal open end and a distal closed end and an externally threaded surface, a socket extending distally from the proximal end and terminating at a proximally facing shoulder and an internally threaded hole extending distally from the proximally facing shoulder and a curved portion formed between the proximally facing shoulder and the internally threaded wall.

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.

Dental prosthesis comprising a dental implant comprising an external thread for screwing the dental implant into a jawbone and an internal thread arranged inside the dental implant. The dental prosthesis further comprises a superstructure having an internal bore and a screw for fastening the superstructure to the dental implant. The screw has a screw head with a cylindrical or conical lateral surface and a shank which adjoins a lower end of the screw head and on which an external thread is arranged. In an assembled state of the dental prosthesis, the screw is inserted through the internal bore of the superstructure into the dental implant and the external thread of the screw engages the internal thread of the dental implant. The screw head comprises a convexly rounded chin between the cylindrical or conical lateral surface and its lower end, with which chin the screw abuts the superstructure in the internal bore in the assembled state of the dental prosthesis.

The disclosure relates to a reconstruction prosthesis including a plurality of prosthesis units connected in series. Each of the prosthesis units includes a main part and a cushion structure. The main part has an abutment insertion opening and an accommodation space. The cushion structure is located in the accommodation space and movably located at the abutment insertion opening and defining an abutment mounting hole connected to the abutment insertion opening. The cushion structure is deformable with respect to the main part.

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.

A fixed hybrid dental attachment assembly is provided. The fixed hybrid dental attachment assembly includes an abutment member, a male member, and a cap. The abutment member has an outer locating surface portion projecting downwardly from an upper end. The male member for attachment to the abutment member has an upper end for engagement within a cap in a recess in a dental appliance, and a continuous, unbroken skirt projecting from the upper end of the male member for engagement over the outer locating surface of the abutment member. The skirt may have a rounded, convex outer surface, and the male member may be constructed from a PEEK material.

The present invention relates to a dental implant set comprising a fixture for insertion into a bore hole arranged in bone tissue having first indexing means, a dental component having second indexing means and being adaptable to the fixture in an engaged position where the first and second indexing means mate and in an intermediate position where the dental component and the fixture are in contact with each other but the first and the second indexing means do not mate, and a fixation screw being adapted for fixating the dental component to the fixture. The present invention also relates to a method for attaching a dental component to a dental fixture.

A semi-synthetic hybrid material having a pH from 7 to 7.4 includes an inorganic fraction and a cross-linked organic fraction. The method for producing this material, and osteosynthesis devices or implants made of semi-synthetic hybrid material are also described.
