Determination of the dynamics of restored teeth by 3D electronic speckle pattern interferometry

Abstract

The results show that the deformation pattern of restored teeth is material-specific but the extent of deformation is primarily limited by the remaining tooth substance.

“…(b) Incremental loading protocol for ESPI analysis. (Kirkpatrick and Brooks, 1998), on cortical bone cubes (Shahar et al, 2007), and on tooth enamel (Lang et al, 2004). The ESPI system of this study has previously been applied on bone (Bottlang et al, 2006) and cartilage (Erne et al, 2005).…”

New Trends in Dental Biomechanics with Photonics Technologies

“…The deformation pattern of restored teeth is material-specific but the extent of deformation is primarily limited by the remaining tooth substance [57]. This technique was also used to develop a non-destructive test for characterizing the modulus of resin-based filling materials, and as it is a non-destructive test, time-dependent effects of composites can be determined using the same specimens leading to substantial time and material savings [58].…”

“…Additionally, these experiments provided mechanical parameters that were averaged over the entire specimen. Photomechanical techniques such as digital photoelasticity, digital moir e interferometry, electronic speckle pattern interferometry and digital image correlation are applied in dental biomechanics to study stress-strain response in intact (Wang & Weiner 1998, Kishen & Asundi 2005a,b, Panteli c et al 2014) and restored root filled teeth (Lang et al 2004, Panteli c et al 2007) in a nondestructive manner under physiologically relevant loads.…”
