Energy dissipation capacities of CAD-CAM restorative materials: A comparative evaluation of resilience and toughness

The Journal of Prosthetic Dentistry

Abstract

Well-balanced physical properties of computer-aided design and computer-aided manufacturing (CAD-CAM) materials are important to ensure the clinical success and longevity of restorations. Therefore, the capacity of a material to dissipate destructive fracture energy by means of elastic and plastic material deformation is of interest. However, little information is available on how to quantify the resilience and toughness of CAD-CAM materials. The purpose of this in vitro study was to investigate and compare the resilience and toughness of CAD-CAM restorative materials and assess their capability to dissipate destructive fracture energy in comparison with a high-gold-content alloy. Restorative materials for 3-unit fixed partial dentures (Alphador No. 1, IPS e.max CAD, Lava Plus, PEEK Optima), crowns and onlays (CERASMART, CEREC Blocs, Lava Ultimate, VITA ENAMIC), and interim prostheses (M-PM Disc, Telio CAD) were investigated. The strain energy density was determined with a 3-point bend test to calculate the modulus of toughness, the modulus of resilience, and the elastic recovery and thus characterize the material properties of resilience and toughness. Data were statistically analyzed with a generalized linear mixed model by u...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
