This 25 years old young man came to the clinic complaining of bad esthetics of old composite veneers. The patient said he wanted to smile more confidently, and possibly proudly with a brand new white and attractive smile.

Fig.2
The black background helps us highlight all the flaws of these restorations. The main flaw is that gingival embrasures were not properly considered when restoring the teeth, so the patient can’t properly floss and now has gingivitis. So, according to the patient’s request, we decided to replace the composite veneers on the upper 8 teeth.

Fig.3
We isolate with the rubberdam and retract the dam and papillae with floss ligatures and we removed the old composite.

Fig.4
We etched the enamel with orthophosphoric acid for 30 seconds, and then thoroughly rinsed (60 seconds).

Fig.5
Note the chalky, frosty matte appearance of the enamel after proper etching.

Fig.6
Bonding is applied with a brush Multiple coats of bonding agent are applied and after 20 seconds air is blown using oil-free syringe to let the solvent evaporate and polymerized perfectly for 60 seconds.

Fig.7
Palatal shells (about 0.5 mm) were built using the Enamel shade, with the aid of the silicone index.

Fig.8
We built the proximal walls using metallic sectional matrices to layer the E shade from the White Dental Beauty CompoSite kit.

Fig.9
White Dental Beauty CompoSite dentin shade Si 1 was used to layer and then shape the mamelons. The White Dental Beauty CompoSite Body shade is light cured for 40 seconds and the light output should be a minimum of 500 mW/cm2.

Fig.10
The final layer of Si E shade helps give the illusion of natural appearance and also for incisal characterization.

The finishing is a crucial part of a direct veneering treatment, to make teeth look natural, to come alive. First of all, the buccal contouring is perfected by using pop-on discs.

Fig.12
Coloring and drawing the grooves can come in very handful when quickly characterizing composite veneers, here with a fine-grained diamond bur.

Fig.13
To create the vertical macro texture, V-shaped grooves were engraved using a carbide bur, which is also great for texture.

Fig.14
After texturing we can remove the rubber dam. Now it’s time to sweeten the surface characterization by using a rubber Eve twist polisher.

Fig.15
Final polishing requires diamond paste. Here I used 3 and 1 micron diamond pastes with a natural goat-hair brush at 1,000 rpm dry and at 10,000 rpm with water irrigation.

Fig.16
A soft felt disc is used with a 1-μm aluminum oxide paste to achieve a very high gloss used at 1,000 rpm dry, and 10,000 rpm with abundant water.

Conclusions

Using simple, single-shade – or two-shade – techniques, combined with the concepts of Whiteology, is the path to having satisfied patients while using a minimally invasive, predictable and repeatable approach.
