The FS data for the time interval from 2-5 min are presented in Table 2. Specifically, it is highlighted that at a temperature of 820 \({}^{\circ}\)C for 4 min and 30 s, the Celtra Duo ceramic showed outstanding FS performance [32]. Analyzing Table 4 reveals that increasing both time and heat units results in slightly lower mechanical performance for e.max CAD [33] than the one presented in Table 3. \begin{table}

* SD: Standard deviation; MPa: Megapascals; FS: Flexural strength.
* IPS e.max CAD demonstrates superior FS performance when using a temperature of 840 \({}^{\circ}\)C for a period of 7 min [34], as shown in Table 3.

Table 3: FS results of the silicate ceramics group in the time range 6–7 min. From Table 6, it is evident that the Vita Suprinity ceramic demonstrated higher FT when the manufacturer's recommended furnace was utilized, with a heat treatment of 840 \({}^{\circ}\)C applied for 8 min, in comparison to Celtra Duo [39].
