Abstract: Background The purpose of this study was to evaluate the efficacy of selective laser sintering (SLS) against the traditional casting method in fabricating customized Co-Cr dental posts, employing 3D coordinate metrology for analysis. Methods A 10 mm post space was prepared in a transparent acrylic block using a red ParaPost XP drill (1.25 mm diameter). An impression of this cavity was taken with a 1.143 mm diameter ParaPost impression post and auto-polymerizing acrylic … Show more
