The present invention refers to a system of prosthetic components consisting of Compensatory Slanted Copings and Abutments of Universal Coupling that function as a set of coupled parts that allow corrections of slants that vary between OQ and 60Q, of fixing osseointeg rated implants, including zygomatic fixations, and it provides a cap, molding transferer and screws for fastening and locking. This system of copings and abutments provides properties of conversion and extension of the implants. Its shape provides better occlusal stability and favorable biomechanics, since the forces are better distributed, diminishing the concentration of tension on the fitting platform of the implant, as well as the screws. The abutments of the universal coupling can be readjusted and be cemented or screwed. In the present system, the superior platform of the coping and the inferior base of the abutment are universalized, since the inferior platform of the coping corrects the slant of the implant. It has screws for fastening and for locking of the coping/abutment set. The characteristics of this system provide great versatility, which allows it to be used in various areas of medicine. |

1. A system of prosthetic coupled components for osseointegrated prosthetic reconstruction comprising a structure, which includes: a compensatory slanted coping, converter and extender, a universal coupling abutment; and a single screw, having a screw head, said system comprising:
said universal coupling abutment comprised of an upper frustum-conical portion and a lower frustum-conical portion, wherein the lower frustum-conical portion has a lower plane surface adapted to abut an upper portion of the coping, converter and extender, said universal coupling abutment also comprising a side hollowed area defined to permit the insertion of said single screw and said screw head positioned within the lower conical portion, to lock the compensatory slanted coping, converter and extender, the universal coupling abutment and an osseointegrated implant into the system of the prosthetic coupled components, said single screw provided to be inserted through a side hollowed area of the universal coupling abutment and a second hollowed area of the compensatory slanted coping, converter and extender and said single screw fastened inside an internally threaded hole of the osseointegrated implant, said single screw being disposed along an insertion axis of the osseointegrated implant that is coaxial with the second hollowed area of the compensatory slanted coping, converter and extender, and at an angel to an axis of the universal coupling abutment; said compensatory slanted coping, converter and extender generally presenting one of a cylindrical or oblong shape defined by a side wall and comprising one of a through hole or the second hollowed area which is concentric and coincides in relation to an insertion axis of the implant;wherein:
said compensatory slanted coping, converter and extender comprises a single flat upper surface and a lower surface, said single flat upper surface and said lower flat surface defining between them an angle from 0° to 60°, which defines a correction angle of the osseointegrated implant respectively between 0° to 60°; said compensatory slanted coping, converter and extender functioning as a coupling piece formed between an interface of the osseointegrated implant and a lower plane portion of a base of the compensatory slanted coping, converter and extender and which provides a connection to the osseointegrated implant, wherein the osseointegrated implant has one of an internal or external hexagon, an internal cone, a Morse cone or a cold welding; said compensatory slanted coping, converter and extender functioning as a universal coupling piece formed by abutting a single flat upper surface of the compensatory slanted coping, converter and extender and a lower plane surface of the universal coupling abutment, said single screw head being stopped inside of the universal coupling abutment and, after said single screw is screwed in an implant hole, said screw keeps the compensatory slanted coping, converter and extender and the universal coupling abutment firmly together with the osseointegrated implant. |
