Clinical Cases, Labside A new smile with only 4 zirconia crowns 14 de nov. de 2023 Case by Kosti Vyshamirski A male patient (47 years of age) presented to his dentist with severe damage to his teeth. His main request was to increase aesthetics, to achieve a more pleasing envisaged aesthetic area. A side request was to achieve a ‘whitening but natural look’. This was achieved by using a lighter colour palette of zirconia and porcelain materials. The final result was achieved through the creation of a wax-up, followed by a mock-up, provisional restoration and finally adhesive bonding of the zirconia crowns. INITIAL SITUATION Fig. 1.
