case report

The patient came to our attention for esthetic rehabilitation; the analysis revealed an old damaged composite restoration that should be replaced on both incisors 11 and 21.
The following case shows the step-by-step direct composite restoration using the Polydentia’s Unica anterior matrix powered by Style Italiano.

4: Unica anterior matrices placed on both incisors 11 and 21. The contoured shape of the matrices embraces the teeth and help the practitioner to better see where the midline is placed. In this case, the stability of the matrices itself does not require wedges or myCustom Resin to stay in position.

5: Incisor 21 has been restored first; this image shows the proximal edges built up.

conclusion

The contoured shape of the Unica anterior powered by Style Italiano allows the clinician to restore the natural proximal and cervical morphologies at the same time in a very predictable way, making the matrices a very useful product for anterior restorations.
