Influence of Loading Conditions on the Deformation Behavior of Human Enamel Studied by Instrumented Indentation

Abstract: As the hardest and one of the most durable load bearing tissues of the body, enamel has attracted considerable interest from both material scientists and clinical practitioners due to its excellent mechanical properties. The aim of this investigation is to determine the influence of different loading conditions on the deformation behavior of human enamel using instrumented indentation and Berkovich indenter. The used samples were fresh intact human premolars, extracted due to orthodontic reasons. Hardness test… Show more

“…Resin-composite materials are considered to be less hard and brittle and to cause less stress build-up in antagonistic teeth compared to ceramics. The present material's properties were within the range of data of human dentine from literature (indentation hardness of 0.4-1.1 GPa and indentation modulus of 12.2-22.9 GPa) [35][36][37]. As the elastic modulus also resembles that of dentin (approximately 15 GPa) [38], CAD/CAM composites could be considered when looking for a biomimetic approach for a dentine replacement [39].…”

“…Dentin has the function of absorbing and distributing the applied stress. It has a distinct microstructure, composed of tubules, which are separated by intertubular dentin, which are responsible for the hydration of the tooth [1].…”
