Adaptation of all-ceramic fixed partial dentures
Abstract Objectives To measure the marginal and internal fit of three-unit fixed partial dentures (FPDs) using the micro-CT technique, testing the null hypothesis that there is no difference in the…
Thermal gradients and residual stresses in veneered Y-TZP frameworks
Abstract Objectives The occurrence of “chipping” of all-ceramic restorations with Y-TZP frameworks has resulted in various designs and cooling procedures recommended for reducing such behavior. In this paper the temperature…
Analysis of interfacial fracture in dental restorations
Abstract Objectives To provide a brief summary of the background theory of interfacial fracture mechanics and develop an analytical framework that identifies the critical factors for the analysis of the…
The influence of chemical structure on the properties in methacrylate-based dentin adhesives
Abstract Objectives The objective of this study was to investigate the influence of the chemical structure of methacrylate monomers used in dentin adhesives on degree of conversion (DC), water sorption,…
Effects of particle size of silica filler on polymerization conversion in a light-curing resin composite
Abstract Objectives The effect of visible light passing through a resin composite with different particle sizes of spherical silica filler on the curing depth and Knoop hardness of the resin…
Evaluation of resin composite polymerization by three dimensional micro-CT imaging and nanoindentation
Abstract Objectives Light-cured composites undergo shrinkage during polymerization. The aim of this study was to evaluate regional shrinkage within a light-cured composite during polymerization by microcomputed tomography and mechanical properties…
Biomimetic remineralization of human dentin using promising innovative calcium-silicate hybrid “smart” materials
Abstract Introduction The hypothesis was that experimental ion-leaching bioactive composites enhance remineralization of apatite-depleted dentin. Materials and methods Calcium-aluminosilicate (wTC-Ba) or fluoride-containing calcium-aluminosilicate (FTC-Ba) Portland-derived mineral powders were mixed with…
