Semidirect Prefabricated Veneers Part 1
In my opinion they must be considered as a new generation of anterior composite restoration to simplify free-hand techniques and to increase the quality of front teeth restorations.
Their best advantage is the thickness of the shells… just 0,3 mm.
So we can use them like contact lenses, just in addition, without preparing the teeth.
For this reason, we can put them on the vestibular side with a glycerine drop.
To show our project to the patient before starting.
To obtain consent and reach an agreement about the treatment.
My favorite indication for Componeers is a having multiple big restorations.
Using this technique we can exploit the chance to cover all the buccal enamel surface with the incredible advantage of move margins in an invisible position.
So, after a correct isolation under the rubber dam…
I removed old fillings
And used a single dentin composite shade to restore the teeth.
Before using composite prefabricated veneers.
I just roughened the composite surface with a diamond bur to improve the adhesion.
Before using a 37% orthophosforic etchant gel on the teeth.
And an etch and rinse, two step adhesive system on the whole buccal surface.
And on the internal part of the Componeer, without curing yet.
The luting protocol is the same as indirect posterior composite restorations
With all the steps of adhesive and heated composite on the internal side of the veneer
We can use all the time we need to remove composite excess with a thin probe.
And a flat dental floss.
The final polymerization was made under glycerine to eliminate oxygen access to the surface.
We need just a very easy and fast time to polish and finish margins.
And the contact point, because the buccal side has a high quality factory treatment.
And this was the final result in only one appointment and just two hours of total working time . We have a lot of advantages with this protocol:
– Single session treatment
– No provisionals
– No lab work needed and low cost
With this new system, we can achieve easy and predictable aesthetic results in anteriors.
A smart solution between direct and indirect restorations to simplify the free hand technique.
And a very good response in tissue stability. If we respect soft tissues, they will respect us with a perfect stability overtime.
Saving and respecting tissues.
The main advantage of the Componeer protocol is to postpone a restoration that involves a greater tooth structure sacrifice ensuring longer life at a lower cost.
