Based on the results of the scientific literature and the clinic, direct composite veneers offer a valid option for aesthetic rehabilitation. The minimally invasive approach, the good color matching as well as the functional and aesthetic biomimetics can offer great comfort and highly satisfy the patient’s expectation.
The patient, 47 years old, came to the clinic complaining about her smile. She presents incongruous old restorations of the upper incisors, thus two direct composite veneers on 1.1 and 2.1 were decided to be performed.

A temporary restoration was fastly performed to prepare a silicon mold guide. The composite was placed without etching the surface, in order to easily allow its removal.

The rubber dam application is mandatory to create an aseptic and dry environment. Two wooden wedges were placed to hold it.

Contouring, finishing and polishing are the most critical steps to obtain the best and successfull restorations. Sof-LexTM Diamond Polishing System (3M, ESPE) can offer to clinicians the best solution for a simply and also satisfactory finishing and polishing technique.

Conclusions



Single session restoration is convenient and economic compared to ceramic approach and may change the smile instantly. The composite gives always the possibility to modify, repair or reshape directly in the mouth easily. The single layer approach, the good tooth-restoration matching, and the unique creamy handling of 3M™ Filtek™ Universal Restorative, offer a perfectly integrated aesthetic restoration.
