to evaluate the influence of core thickness and fabrication stages on the marginal accuracy of ips e.max press crowns.twenty ips e.max press crowns, 1.5mm thick, were fabricated on metal dies. the crowns had two different core thicknesses, 0.8mm for group a and 1mm for group b, ten for each group. marginal gap was measured after each stage of core fabrication, veneering and glaze firing. the sp...

Purpose: The main aim of this paper is to present a concept marginal vertical income convergence. This method allows determine the individual contribution objects (countries, regions) observed general process real Design/Methodology/Approach: Proposed methodology avoid limitations classical analysis To check cross-country stability parameters and assess an convergence process, separate regressi...
