Aesthetic restoration of anterior teeth with different coloured substrates using digital monolithic zirconia crowns: two case reports

ABSTRACT

Tooth discolouration and the existence of metallic substrates increase the difficulty of restoration to reproduce natural and aesthetic appearance. The commonly used veneered zirconia restorations have a high risk of porcelain chipping, and the monolithic zirconia restorations cannot always achieve satisfying aesthetics. The newly developed self-glazed monolithic zirconia restorations digitally manufactured by additive technique have colour- and translucency-gradient characteristics. They could mask the different coloured substrates and achieve a natural look simultaneously. This clinical report describes the prosthodontic treatments of two patients with different coloured substrates in the anterior region. Both functional and aesthetic outcomes are satisfactory after 1–3 years of follow-up.
