Using the Front Wing Technique

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.

Occlusal view after completion of all restorations and before starting the finishing procedure.

central diastema closed with direct composite restorations

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

glossy composite restorations

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

Lateral view after one week.

Situation after 6 months. Please note the migrated papilla.


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.

Ready, steady, mock-up, go!

The mock-up is an essential tool for so many purposes when it comes to esthetic treatments. In this article, Dr Pavolucci shows how to use it to restore a multiple diastema.
