Résumé
With the establishment of CAD/CAM technology, competing lithium silicate based formulations have been introduced for clinical use, but little is known about their phase composition. Here we investigate a commercially available SiO With a focus on the final stage of crystallization, we characterized the dimensional changes in the crystallographic structure of the residual Li An increase in crystallization temperature from 840 to 880°C resulted in a significant reduction of the Li These findings help to establish recommendations for adjustment of the crystallization protocol, which has potential to increase the clinical reliability of the material investigated.
