The Ductility, Brittleness, and Fracture toughness

Abstract

There are many important mechanical properties related to dental materials like ductility, brittleness, and fracture toughness. Those properties describe the resistance of materials to plastic deformation, crack propagation, and fracture under the applied force. It is important to predict how dental materials react to forces (masticatory and fabrication) to prevent their early fracture and prolong their proper clinical performance.
