Rubber dam isolation is ideal in cases of diastema closure because not only it provides absolute isolation, but it retracts the gums, allowing access for the creation of an ideal profile.

After the surfaces were selective roughened and clean with aluminium oxide 50 micron sandblasting, enamel was etched using 37% phosphoric acid.

Fig.5
One Coat 7 Universal Adhesive was used on the etched areas, using a large Styleitaliano brush to better spread the bonding.

Fig.6
Building the proximal walls is easy with thin metallic sectional matrices. A single A2/B2 shade from the Brilliant Everglow composite kit was used.

Fig.7
A 60 seconds curing high power led lamp session was used for oxygen layer inhibition.

After shape is complete, finishing and polishing can be done using a multi blade flame bur first to remove the bonding excess in the cervical area.

Conclusions

A direct composite approach was chosen to fix her smile on the concept of minimally invasive treatments.
