This patient presented with gross caries of 7 necessitating extraction, loss of vertical dimension from GERD-related erosion and bruxism, and financial limitations that made implant therapy less favorable.
Minimal restorative space present. A PFM cantilever from 8 was chosen because it allowed for conservative lingual reduction while still providing the esthetics needed in the smile zone. The facial margin was prepared as a 120° porcelain butt joint and maintained a metal lingual design. The preparation was designed as a traditional wing-style transition for added retentive and resistance features, and immediately sealed. The laboratory tribochemically treated the intaglio surface to enhance bonding to the metal substructure. Scotchbond Universal Plus with RelyX Ultimate were used for cementation. Utilizing every available source of retention, the facial porcelain was also bonded to maximize resistance to debonding.
The cantilever pontic was completely relieved from occlusion, and an ovate pontic design was developed immediately following extraction to improve emergence profile and tissue architecture. A Maryland-style wing extension onto #6 was not utilized due to the increased restorative complexity associated with path of draw and pin retention requirements. 🦷
