The aim of this study was to evaluate the effect of intraoral scanning versus desktop scanning on the retention and adaptation of maxillary denture bases in completely edentulous patients.
The use of intra oral scanners (IOS) for rehabilitation of completely edentulous patients is still limited due to the difficulty in scanning large edentulous areas that are smooth and devoid of features. The stitching process can be defective, especially in the palatal area, where, the outmost deviations were reported in the palate when digitizing edentulous jaws with intraoral scanners. The main challenges for a fully digitized complete denture workflow are the digital impression of mobile tissues with functional border molding and the digital registration of the jaw relationship.
