Conservative Class V
A 36-year-old female patient presented with non-carious abfraction lesions in the premolar area (teeth Nos. 28, 29, and 30). After discussion with the patient, we chose to restore these Class V lesions with direct composite. I chose Amaris (VOCO) for this case. In addition to its simplifi ed proprietary shading system, one of the nice features of Amaris is that it has a fl owable liquid opaque for blocking out dark areas.
To prepare the teeth, I used the Waterlase MD (Biolase Technologies) all-tissue laser to roughen the surfaces of the lesions. I beveled the enamel in the cervical third, both to better blend the composite and to achieve additional micromechanical retention. I also used the laser to trim back the soft tissue and expose the gingival margin. As many clinicians have experienced, one of the challenges of Class V restorations is getting a good seal at the gingival margin. I get the supragingival margin with the laser by trimming the marginal tissue slightly and using the fl owable as the fi rst increment. This technique helps seal the margin very well.
After I etched the enamel, I then applied the opaque Amaris shade HO (VOCO). Finally, I placed Amaris shade 04, a darker shade that simulates the darker dentin. When I use the Amaris system, I choose the shade of the dentin based on the preparation. That way, I can adjust the value by using 1 of the 3 incisal shades to achieve great esthetics. After fi nishing and polishing, the result is very lifelike and natural.
