Semidirect Prefabricated Veneers Part 1

Ortho and Kids - Semi directs - Indirect anteriors

In my opinion they must be condiderated as a new generation of anterior composite restoration to simplify freehand technique 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 lens concept, 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 her agreement

My favourite indication for them is a high number of big restorations

Using this technique we can exploit the possibility of covering all the vestibular enamel surface with the incredible advantage to move margins in an invisible position

So, after a correct isolation under the rubber dam

I took the place of old fillings

With a single dentin shade

Before using composite preformed veneers

Fig. 13

I just roughened composite surface with a diamond bur to increase the adhesión

Before using an orthofosforic 37% etchant gel on the teeth

And a etch and rinse two step adhesive system on the all vestibular side

And on the internal part of the componeer, without polymerizing

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.

Before polymerizing

The final stages of polymerization was made under glycerine

Fig. 23

which eliminated oxygen access to the surface

Fig. 24

We need just a very easy and fast time to polish and finish margins

Fig. 25

and interdental contact point because the vestibular side has a high quality factory treatment

Fig. 26

And this was the final result in only one appointment and just two hours of total working time…

So. We can have a lot of advantages

Just one working session

No temporary restorations

Lab free and low cost

Fig. 27

With this new system, we can achieve easy and predictable aesthetic results in anteriors

A smart solution between direct and indirect restorations to simplify free hand tecnique

And a very good reply by tissue health

If we respect soft tissue, they will respect us with a perfect stability during the time
