Treatment of a young patient with zirconia veneers

Behandeling van een jonge patient met zirconia veneers

Case by MDT Daniele Rondoni and Dr. Enzo Attanasio.

Veneers made of zirconia? In some cases, like the one presented below, monolithic zirconia veneers may be an option. Reasons for selecting a latest-generation zirconia such as “KATANA™ Zirconia” YML include its very high translucency and a wall thickness of only 0.3 to 0.4 mm supporting minimally invasive tooth preparation. Due to a highly automated production procedure, the manual effort involved may be reduced, while highly aesthetic outcomes are possible.

Fig. 1. Initial situation: Young female patient with misshaped and misaligned maxillary incisors. Digital smile design is used to reveal the ideal proportions and positions of the anterior teeth.

Fig. 2. Ideal tooth proportions and positions displayed over a picture of the teeth after orthodontic treatment and the creation of a mock-up. The positions are ideal and the tooth shapes obtained with the mock-up only need some minor adjustments.
