Study summary

This is a randomized, prospective clinical trial. The aim of the project is to assess the clinical performance of three types of tooth-supported crowns; monolithic high translucent colored zirconia, crowns of high-translucent colored zirconia with a mini-veneer buccally and crowns of lithium-disilicate glass-ceramic. Crowns will be placed on posterior teeth and evaluated from an esthetic and functional point of view, to identify if there are any differences between the materials.
