Mean bending strength [MPa] of the six groups (A-F) after incubation for 24 h (24-h) and six weeks (6-w). The minimal requirement of 50 MPa according to ISO 5833:2002 is marked with a red horizontal line [27]. Preparations from Group E and F have surpassed this threshold after incubation for 24 h with a mean bending strength of 57.6 ± 1.2 MPa and 50.4 ± 4.4 MPA, respectively
