A clinical case by our Community member Dr. Matthias Kuhn

Minimally invasive dentistry contains a variety of treatment options to restore lost tooth structures or even construct new tooth shapes. An additive restoration concept, in combination with composite or ceramic restorations, secures the protection of tooth structure. The preferences of the dentist determines the choice of the restoration material. In this case a direct resin composite restoration was chosen to close a diastema between 11 and 21.

After the first surface treatment, I noticed the contour deficit on 11 and I added a small amount of composite in the cervical area.

Frontal view after one week. There was no need to polish the restorations again, as they showed a good integration.

Conclusions

The Front Wing Technique is a precise way to close a diastema because of its workflow and the good control of the aspired emergence profile.
