“…The microslits on the zirconia disks were fabricated in a simple reticular pattern because the purpose was to examine the SBS with or without microslits. In general, since resins exhibit a relatively high level of water absorption, and their coefficient of thermal expansion (CTE) is higher than that of zirconia 21) , a reduction in adhesion strength might be expected as a result of long-term exposure to moisture and significant temperature changes in the oral cavity. Therefore, the change in the SBS before and after thermal cycling was examined for indirect composite resin and acrylic resin.…”

“…Polymerisation process involves certain amount of polymerisation shrinkage (PS), which could be due to chemical, thermal or post contraction 9 . During chemical contraction, the van der Waals distance between the atoms of monomers are reduced from to ~10 4 Å ~1.0 Å, resulting in bulk contraction in cured resin, i.e., volumetric polymerisation shrinkage 1012 . Though the effect of thermal contraction due to exothermic reaction and cooling back to room temperature is minimal, internal stresses could be induced which could be detrimental to the restoration 9 .…”

“…Assuming the dental resin is macroscopically isotropic, shrinkage is also assumed to be equal in all directions, i.e., volumetric shrinkage is assumed to be thrice of linear shrinkage 31 . Linear shrinkage of dental resins could be measured using dilatometer 32 , bonded disc based Watts method 32 , strain gauges 33 , scanning laser beam method 34 , video imaging technique 35 , linear displacement and force 36 and by using fibre optic sensors 12,37,38 .…”

“…The finite element modeling and finite element modal analysis are carried out for the original design of the structure. Rajan, G. et al [3] used optical fiber sensing technology to evaluate the physical properties of dental resin composites. The modal and frequency of the structure are predicted as the dynamic information under the undamaged state of the structure.…”
