Abstract
Objectives: The aim of the study was to evaluate effect of divergence angle. (12o , 6o) and intra-pulpal Depth. (3mm, 5mm) on marginal adaptation and internal fit of premolar endo-crowns using intraoral scanner: 3Shape “Trios 4”.Materials&Methods: The preparation was done on a Four extracted endotreated premolars, preparations were done using Carbide Carburundom diamond Endmil. Premolars was divided into four groups, each group has different angel and different intra-pulpal depth. All the preparations were scanned with trios 4 intraoral scanner 7 times (n=7). All the samples were designed with Exo-cad software and milled using VHF Milling Machine. Marginal adaptation measurements were done using Dino-lite digital microscope. Results: regarding divergence angle 6° had a significantly higher value than 12°, regarding intra-pulpal depth 5 mm depth had a significantly higher value than 3 mm depth. Conclusion: 12 degree divergence angle shows better marginal adaptation than 6 degree and 3 mm depth shows better marginal adaptation than 5 mm.
