Injection molding technique in direct veneers with Solventum™ Filtek™ Easy Match Flowable Restorative
About the case
60-year-old male patient showing progressive signs of wear on the lower incisors. Dr. Bonacina decided to proceed with direct veneer restorations using the injection moulding technique.
Challenge
One of the main challenges in injection moulding cases with diastemas is the management of the emergence profiles. It is essential to create correct contours and properly polish the interproximal areas to allow effective and adequate oral hygiene.
Outcome
Solventum™ Filtek™ Easy Match Flowable Restorative (add link to PDP) has excellent shade blending properties, even in full-thickness restorations. This flowable composite provides appropriate optical properties, enabling natural-looking results, even with a single-shade technique, and offers excellent polishability.
