Zirconia post-pressed ceramic core-supported all- ceramic crown: Case reports and 4-year follow-up.

Esthetic restorations involving anterior teeth pose a challenge to any clinician. Increasing patient expectations and the search for metal-free restorations have led to the birth of all-ceramic restorations. All-ceramic restorations must combine the mechanical properties of metal and optical properties of ceramics to be accepted as an alternative to porcelain-fused to metal restorations. At present, zirconia-based materials stand out as the strongest, most esthetic and biocompatible material available as posts for all-ceramic restorations. All-ceramic crowns require all-ceramic post and core as foundation restoration, as they help to bring about the best possible esthetic outcome. Here, a zirconia prefabricated post was heat pressed with the core material to obtain a monobloc. This provided the foundation for the restoration of the tooth with all-ceramic crown. The article presents clinical cases and a 4-year follow-up of three cases treated using all-ceramic post/core/crown. The procedure is presented in detail. [ABSTRACT FROM AUTHOR]
