Esthetics anterior crowns with monoblock zirconia ceramic system: A Clinical Case Report

Objectives: Monoblock yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) ceramics, became one of the most current material which exhibits high mechanical and aesthetic properties compared with other ceramics. Monoblock zirconia is a biocompatible non toxic material with low bacterial adhesion and which eliminates multilayering of ceramics.
The purpose of this report was to restore unaesthetics appearance of maxillary anterior teeth with full ceramic restoration.

Methods: A 27 year-old male patient with hypomineralized enamel, deep bite and wear on occlusal surfaces which indicates the patient has bruxism. Full ceramic restorations were planned for maximum light translucency and natural appearance but deep bite and the bruksism avoided the use of lithium disilicate ceramics. Conventional zirconia systems could not be used due to limited occlusal space. Monolithic zirconia was chosen for its’ translucency for anterior esthetics and strength.
Results: No esthetic and functional complications were reported after 12 months.

Conclusions: Prosthetic rehabilitation using monolithic zirconia may help to prevent complications associated with bilayered ceramics systems.
