Maxillary intaglio surface of CNC milled versus 3D printed complete denture bases – an in vitro investigation of the accuracy of seven systems.

The accuracy of the intaglio surface of maxillary complete dentures produced with a variety of digital manufacturing systems have been comprehensively investigated, however, not for multiple systems in the same study. This in vitro study endeavors to measure and compare the accuracy of the intaglio surface of maxillary complete denture bases constructed with different photopolymerization-based 3D printing and CNC milling systems.
