Case report: Vertical preparation protocol for veneers.

The biologically oriented preparation technique (BOPT) consists of a vertical preparation of the tooth that involves a reduction to zero of the emergence anatomy, the creation of a new finish area, and immediate temporization, so that the gingiva is supported by a suitable prosthetic restoration. To this effect, it is not the restoration that adapts to the gingiva, but the gingiva that adapts to the restoration. This technique not only allows the gingiva around the tooth to stabilise, but over time it will also facilitate the achievement of a predictable coronal migration of the gingival margin. The present paper describes the protocol from dental preparation to the cementation of the BOPT veneers, highlighting the differences with the established protocol for full coverage crowns and the protocol we have followed for many years for veneers with finish lines.
