From: Shear bond strength of ceramic laminate veneers to finishing surfaces with different percentages of preserved enamel under a digital guided method

Surface Surface treatments
Porcelain 5% HF for 60 s; primer for 60 s
Enamel 37% H3PO4 for 30 s; single bond for 10 s
Dentin 37% H3PO4 for 3 s; single bond for 10 s
  1. H3PO4: phosphoric acid (total etch, ivoclar vivadent, schaan, liechtenstein). HF: hydroflfluoric acid (vita ceramics etch, VITA zahnfabrik, Bad Sackingen, Germany)
