English technical abstract
This white paper develops the broader concept of accuracy within a more specific CAD/CAM context. It notes that intraoral scanners can produce different data, making it important to use a library appropriate to the scanner, scan body and manufacturing workflow.
The document also emphasises the model stage of the digital workflow. A printed model is not automatically accurate simply because it was generated from digital data. Printing accuracy, resin, offset and digital-analog seating must be verified and calibrated.
What the article covers and how to read it
Relevance for the laboratory, dental practice and technical support
- When introducing a new printer, resin or print setting, verify how the analog seats in the model and whether the library or offset requires adjustment.
- When deviations recur, it is better to identify the weak point in the workflow than to automatically suspect a single component.
- For the website, this article forms a useful bridge between CAD libraries, digital analogs and verification of printing accuracy.
