About the Case

A male patient in his mid-40s showing severe signs of erosive wear. Full-mouth rehabilitation was indicated to stop lesions progression and get the original vertical dimension back. Orthodontic therapy was planned as first step for better alignment before the restorative execution.

Challenge

The main challenge lies in restoring function and VDO in a severely eroded dentition while balancing adhesion, occlusion, and longevity using a minimally invasive and economical approach.

Pre-op situation after aligners therapy. Multiple erosive lesions are visible.

Old composite removal and enamel conditioning with 29 μm alumina.

Close-up of upper front teeth with blue dental material applied to some teeth and one central tooth partially covered

Enamel etching for 15 seconds on teeth to be restored in the first round.

Outcome

Composite injection molding is established as long-term interim treatment and offers significant advantages, but success depends on precise planning, etiological control, and meticulous execution.

3M™ Filtek™ Supreme Flowable Restorative has appropriate optical properties for life-like results, offers excellent polishability, and wear resistance.
