Worn teeth are never straight forward to restore. Neck wear (Class V’s) on a tooth with existing porcelain work requires the ability to bond to multiple substrates. Micro air abrasion must definitely be used here. The e-max substrate must be prepared using 5% hydrofluoric acid before the tooth surface is prepared using 33% orthophosphoric acid. 2% chlorhexidine was sacrificed for a totally dry substrate as we needed to use a silane (GC Multi-Primer) coupling agent containing MDP and MDTP. Finally, G-Premio Bond was used before layering using Essentia U to full form.
