ABSTRACT
<p><b>OBJECTIVE</b>To introduce the double scanning for producing computer aided design and computer aided manufacture (CAD-CAM) zirconia crowns, and to compare Procera with Everest CAD-CAM system by observing clinical effects of the crowns.</p><p><b>METHODS</b>Forty CAD-CAM zirconia crowns (10 crowns by Procera, and 30 crowns by Everest) were evaluated, and the examination criteria included: marginal fit, aesthetics, gingival health, retention, and fracture. All of the zirconia copings were produced using double scanning. Procera system and Everest system use contact scanner and optical scanner respectively.</p><p><b>RESULTS</b>The observation time for the crowns ranged from 6 to 24 months. The results of clinic evaluation were acceptable in all restorations.</p><p><b>CONCLUSIONS</b>Double scanning could be used to produce complicated zirconia copings by CAD-CAM in order to get proper symmetrical porcelain length. It was easier to make complicated coping with contact scanner than with optical scanner.</p>
