**5. Conclusions**

The authors of this study investigated the mechanical properties (indentation depth (hr), Martens hardness (HM), indentation hardness (HIT), indentation modulus (EIT), elastic part of indentation work (ηIT), and indentation creep (CIT)) of CAD/CAM resin-based composites with instrumented indentation testing. The Martens hardness and energyconversion capabilities of eleven different CAD/CAM composites were investigated with a reference to clinical application. Within the limitations of this study, the following conclusions can be drawn:
