Martens Hardness of CAD/CAM Resin-Based Composites

(1) Background: The properties of CAD/CAM resin-based composites differ due to differences in their composition. Instrumented indentation testing can help analyze these with respect hardness, as well energy-converting capabilities viscoelastic behavior. (2) Methods: Eleven materials were investigated using instrumented testing. Indentation depth (hr), Martens hardness (HM), (HIT), modulus (EIT), the elastic part work (ηIT), and creep (CIT) investigated, statistical analysis was performed one-way ANOVA, Bonferroni post-hoc test, Pearson correlation (α = 0.05). (3) Results: All parameters revealed between analyzed materials. Besides hardness-associated (hr, HM, HIT), demonstrated properties. subsequent ANOVA significant (p < 0.001). A 0.01, >0.576) HIT, or EIT identified. (4) Conclusions: Due found materials, certain could show superior stress-breaking than others. consequential reduction stress build-up may prove beneficial, especially for implant-retained restorations patients suffering from parafunctions.
