Lithium disilicate glass ceramic crown
Web9 apr. 2024 · For some materials (i.e., composites, glass-ceramic, lithium disilicate), SPR prediction accuracy might seem better with SECT compared to DECT. This is mainly tied to the fact that the HLUT used in our institution and in this study has a maximum SPR value of 2.602 when using SE-140-SACT, which may be incidentally closer to the measured value.
