Polymer-based restorative materials

Table 2: Measured flexural strength for the materials, in megapascal. (Shade A3, if available).

Comment: The flexural strength of the materials tested varied from 82 MPa to 159 MPa for materials regarded as suitable for restorations of occlusal surfaces according to the manufacturer.
For materials not indicated for occlusal surfaces the flexural strength varied from 62 MPa to 122 MPa. All materials tested complied with the requirements of ISO 4049.

Materials regarded as suitable for restorations of occlusal surfaces:

Requirement, ISO 4049 (MPa), Type I ≥ 80

Materials not indicated to be used for occlusal surfaces:

Requirement, ISO 4049 (MPa), Type II ≥ 50
