CUSTOMISED DENTAL ABUTMENT FORMED OF TWO CUSTOMISED PARTS

摘要

Disclosed is a dental prosthesis including an implant, a customised abutment, a restoration and an implant screw for securing the customised abutment to the implant, wherein the implant includes a screw bore extending from a first end of the implant for receiving at last a part of the implant screw, the customised abutment includes a through-going bore for receiving at least a part of the implant screw, the screw bore and the through-going bore are coaxially aligned along an implant axis when the implant screw is arranged in the screw and through-going bore, the abutment includes a customised abutment base and a customised abutment top where the customised abutment base and the customised abutment top defines an assembly axis along which they were assembled during manufacturing, where the implant axis is different from the assembly axis.

主权项

1. A method for designing a virtual model of a customised abutment for use in designing a virtual dental prosthetic comprising the customised abutment, an implant and a restoration, the method comprising:
obtaining a digital data set representing a dental situation of a patient comprising information on implant type, position and orientation along an implant axis, designing a customised abutment by designing an implant surface for contact to the implant along the implant axis and a restoration surface for contact to a restoration, where an emergence profile of the abutment is designed which separate the implant surface and the restoration surface, splitting the customised abutment into a customised abutment base, which is suited to be arranged adjacent to the implant, and a customised abutment top adjacent the customised abutment base, where the customised abutment base and the customised abutment top extends along an abutment axis.
