for marginal fit. Next, all four veneers were
tried-in together with a small amount of
transparent try-in paste to confirm contacts
and aesthetics. The porcelain was prepared
and the teeth treated with a 5th generation
bonding agent (Excite F single), before
seating with a light-cure-only veneer resin
cement (Variolink Veneer). Occlusion was
refined and the margins polished.
Conclusion
Lithium disilicate restorations (IPS e.max
Press) enable dentists to offer patients a
conservative alternative while transforming
the appearance of their smiles. With
lithium disilicate, achieving translucent
incisal effects, such as detailed dentine lobe
structure and dynamic translucency, often
requires cutback and layering. However, the
availability of Opal lithium disilicate ingots
enable stained and glazed restorations to be
fabricated that blend in seamlessly with the
remaining dentition. In the presented case,
the patient was happy with the need for only
minimal tooth reduction, and more than
pleased with the function and aesthetics of
the IPS e.max Press restorations using the
Opal 1 ingot.
