This young patient came seeking for the closure of the spaces between teeth 13-12-11-21-22-23, which presence was due to a discrepancy of the dental-alveolar mesio-distal space (Altered Bolton Index).

Spaces were distributed quite evenly on both sides between canines, laterals and central incisors.

After providing proper isolation, ligatures were done on all the teeth to expose the cervical area and retract the soft tissues.

Closure of the central diastema between with a single shade mass of Body A2 composite. A posterior matrix was placed vertically to build up the proximal walls of the two teeth.

Closure of the diastemas between teeth 12-11 and 22-21 was managed in the same way, again with a single shade mass of Body A2 composite.

Two week check-up. As we can see, the papilla migrated coronally, guided by the new emergence profiles of the teeth.

Many patients just don’t think about how easy and fast is to completely change the look of a smile like this. Diastemas are not a big deal to treat, but their closure can give amazing results. A single visit treatment with just one shade, and freehand is enough to obtain a result that is smile-changing.

Post-orthodontic treatment with direct composite veneers

Direct composite veneers are nowadays a great instrument to achieve highly aesthetic results, with a low financial effort, and without the need for tooth preparation.
