Abstract
The invention relates to a specimen part for creating a stress-free fit, a so-called passive fit, of implant-supported and/or abutment-supported bridges and bars by means of a CAD/CAM tool for the creation of restorations, and to a method for creating a restoration from a digital model of a patient's jaw provided with at least two implants and/or abutments. The model is determined by means of an intraoral scan. In order to improve the precision of restorations and to shorten the production process, provision is made that the specimen part per implant and/or abutment has a scannable structure, preferably at a defined distance and angle to the implant and/or abutment.
