Abstract

The invention relates to a specimen part (1) for creating a stress-free fit, a so-called passive fit, of implant-supported and/or abutment-supported bridges (2) and bars (3) by means of a CAD/CAM tool for the creation of restorations (5), and to a method for creating a restoration from a digital model (15) of a patient's jaw provided with at least two implants and/or abutments, wherein the model (15) is determined by means of an intraoral scan (14). In order to improve the precision of restorations and to shorten the production process, provision is made that the specimen part (1) per implant (4) and/or abutment has a scannable structure (6), preferably at a defined distance (7) and angle (8) to the implant (4) and/or abutment. In the method according to the invention, a specimen part (1) is produced from the model (15) by means of CAD/CAM, the specimen part (1) is checked in terms of its dimensional match to at least two implants (4) and/or abutments and if necessary is corrected, the specimen part (1) is scanned, and a digital model (15) of the optionally altered specimen part (1) is generated, which model is used to generate a restoration (16) manufactured by CAD/CAM.
