Prosthetic Treatment
A diagnostic bisacryl (Luxatemp Flouresence Zenith/DMG) was cured and the esthetics/phonetics were assesed.
With the bisacryl mock-up in place, the tooth preparation was completed to the ideal depth for porcelain veneers and an all ceramic crown. (Fig. 4)

This preparation technique is driven by the final restorations to avoid unnecessary tooth reduction, thus it is highly conservative. (Fig. 5)
Fig. 5 Finalized tooth preparations
Definitive porcelain veneers and an all-ceramic crown (IPS e.Max; Ivoclar Vivadent) were fabricated and cemented using a dual cure resin cement (Nexus 2: SDS Kerr) according to the manufacturer's reccomendation. (Fig. 6)
