Question 1

Does any type of wear to the tooth need to be done to receive the porcelain dental contact lens?

Accepted Answer

The grinding of the tooth should only be done to millimetrically reduce the thickness of the tooth enamel, removing retentive areas that could hinder the insertion of the porcelain veneer, since the dental contact lens needs space and sufficient thickness for it to when glued, it does not protrude or bulky in the mouth, even if minimal to correct the initial position of the tooth and hide stains that are present.

Question 2

What are the differences between resin veneers and porcelain veneers?

Accepted Answer

Durability and quality of aesthetic results are advantages of the porcelain technique over the resin version in veneer treatments. And this stems from the better optical properties, resistance and durability of porcelain over resins, especially in treatments with multiple teeth and with high aesthetic demands.

Question 3

What situations contraindicate treatment with resin or porcelain lenses?

Accepted Answer

Intense modifications are contraindicated for the dental lamination technique. 
Examples of this are poorly positioned teeth (crowding) as it would take a lot of this to be able to place a Lens in the aligned position, and this great wear of the enamel is a treatment that is not at all conservative.
The secret is to always be conservative and prevent tooth enamel because once it is lost it will never regenerate, so in cases of misaligned teeth the patient needs to undergo orthodontic treatment beforehand to align and level the teeth.< /p>

Question 4

What is Facet or Resin Lens?  What are the indications for the technique?

Accepted Answer

It is a composite resin laminate for aesthetic covering of the external part of the teeth.

Question 5

Does the dental contact lens stain over time due to dyes (coffee, wine, tea, soda, cigarettes, etc.)?"

Accepted Answer

The dental contact lens is made of porcelain so it does not stain. However, like resins, they lose their shine and change color over time.

Question 6

How long do dental contact lenses last?

Accepted Answer

Dental dental contact lens can last from ten to thirty years. Porcelain is an inert and biologically compatible material. The surrounding tissues, such as the surface of the tooth under the porcelain and the gum, can undergo changes over time, such as caries and gum recession, respectively. What guarantees the longevity of the dental contact lens is correct oral hygiene and periodic visits to the dentist.

Question 7

How many appointments are needed for dental contact lens placement?

Accepted Answer

For the porcelain technique: Three appointments are required – Design, Preparation, Cementation. In the first consultation, the design of the teeth and smile is done. The second appointment involves the preparation of the teeth and the mold needed to start making the dental contact lens. The third and final appointment is the final cementation of the lenses. 
 
For the resin technique, only 1 long appointment can be performed to transform the smile on all teeth in an arch, as this technique does not require wear on the enamel structure.

Question 8

If dental contact lenses are made only on the upper teeth, will the lower teeth be a different color?"

Accepted Answer

This is an important factor and should be discussed with the patient during the initial evaluation about modifying the smile so that, at the end of the treatment, the teeth can form an ideal and harmonious smile. In most cases, I always try to follow the color of the inner teeth after the patient undergoes teeth whitening before we start with the lenses, the work is more beautiful and the colors are more harmonious.

Question 9

Is it true that, over time, resin veneers turn yellow and lose their shine?"

Accepted Answer

Yes. Although the problem of yellowing and loss of brightness also occurs in the porcelain technique as well, in resins the loss of quality is faster and more intense compared to the porcelain technique.

Question 10

What are parafunctional habits and how do they interfere with treatment?

Accepted Answer

Bad habits forcing the tip of the anterior teeth, such as biting pens, nails and other objects are considered parafunctional. Depending on the intensity with which they occur, they bring high risks for fractures and detachment of the resin and porcelain.

Question 11

Can the radical smile transformation treatments seen in artists and celebrities be performed using the technique with resin veneers?

Accepted Answer

Yes, as long as the professional uses the highest quality materials and has experience and craftsmanship to perform an excellent and realistic manual technique.

Question 12

My tooth has darkened due to root canal treatment. Can I recover it through the technique with composite resin?

Accepted Answer

Depends on the intensity of the darkening. The most modern resins have color systems for blocking darkened tooth structures.

Question 13

If I break off a piece of a resin veneer, can I get it back?"

Accepted Answer

Yes. Incidentally, this is the most interesting characteristic of laminates in the resin technique, and which is lacking in the porcelain-based technique (facets, lenses and fragments). Because once the Porcelain is chipped or broken there is no way to repair it, and you need to remove the contact lens and make a new one, and it does not always remain the same color as the neighboring teeth.
