System of compensatory slanted copings, converters and extenders and abutments of universal coupling over osseointegrated implants

Abstract

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.
