These terms are synonymous of thin structures made of resin or porcelain (ceramic) in the doctor's office in a laboratory, having different thickness depending on the case. When the structure is very thin we speak about lenses, when they have an average thickness we speak about sheets or veneers. Many people relate the term veneers to natural tooth wear, nevertheless, in most cases this is not necessary, the priority always is to preserve the dental enamel, but, if is necessary, wears are realized by minimal invasion in the dental enamel.
They are structures in sheet shapes made in a dental laboratory. They cement or adhere on the natural tooth to the one that before has conditioned the enamel with adhesives. In some cases, it is necessary to reduce a minimal part of the dental surface (enamel) to create a definite margin where it is going to fit the sheet or veneers.
The composite or resin is a pasta that the Dentist places directly on the tooth without the dental enamel being spoiled, hardens with a halogen light acquiring a hard consistency. The composite veneers are reversible, it is possible to retouch or realize some change wished by the patient before the procedure is finished.
Though the priority is to preserve the structure of the tooth, in some cases preparation is realized or carved in order to create a space or a definite margin where it goes away to seat the veneers or sheet.
It is painless, the use of anesthesia is not necessary, does not generate traumatism or sensibility.
For porcelain sheets are necessary two visits. The first one to prepare the teeth and to take records that are sent to the laboratory and the second one to adhere the sheets on the teeth. The first visit includes the clinical analysis and X-rays. When the cases are complex, analyses can be done on models or computerized to have a nearest prediction to the final result. For the composite sheets or resin only is necessary one session. The dentist places the composite or resin like sculpture, hardens it, pule and polishes in the same day. also it can be required radiographic analyses, model analysis or computerized.
The veneers or sheets made of porcelain last between 10 to 15 years. The veneers or sheets made of resin last between 2 to 5 years, nevertheless, it is necessary to bear in mind detail as for example the work of the specialist or the habits of the patient. The sheets of resin get worn out more rapid when the patient brushes himself with a lot of force or uses a whitening toothpaste. If in a few years the sheets are spoiled, the color of the natural teeth will be revealed being seen less white. If the sheets are very spoiled it is possible to replace for new ones with a different color if the patient wishes it.
In the top are placed between 6 to 12 sheets (Lenses or veneers) of porcelain or resin to include the extent of the smile. Also they can be placed between 6 to 12 sheets in the low part.
The sheets of porcelain or resin can be performed on patients of any age.
• Do not eat nails (Onicophagy) • Good oral hygiene in house to avoid not wished spots. • Perform every three or four months a prevention or dental cleanliness in the doctor's office. • avoid to bite food or hard objects.
If the intention is to improve the color we must use a whiter tone resin that the patient wants, for it, a very thin layer is made that will avoid the overlays or bigger teeth, having done a very thin layer it is possible to reveal a bit the tone of the natural tooth.
Yes, we can mold and make bigger size the veneers, respecting the width of the tooth base and the margin of the gum, to avoid periodontal problems or of gums.
The best thing is to close the spaces with orthodontics. In case there are spaces and the teeth are small, we can close the spaces and increase the size of the tooth with the sheets as long as let's not exaggerate in the proportions. In cases like Bolton's Discrepancy where the spaces cannot be closed by orthodontics, the sheets can be perform by aesthetic and functional ends.
The sheets of resin can turn less white with the passage of time along two reasons: 1. Bacterial plaque accumulation (calculations), extrinsic spots (food, drinks and cigarette). 2.sheet thickness wear. it happens with a very strong brush or whitening toothpaste uses, since these generate an effect of friction that is spoiling the sheet to the point that can observe the color of the natural tooth.
The sheets of resin tend to get dirty in the surface and especially about the gums and in the middle of the teeth with the passage of time; nevertheless, this depends on the habits and cleanliness of the patient. To prevent the sheets from getting dirty there is recommended to the patient to wash his teeth whenever it consumes a food, if the teeth remain without washing more than 15 minutes the stains will be adhering. If the sheets of resin meet less white, you can ask for an appointment for a dental cleanliness and to observe that the color returns to become a bit whiter.
The teeth must be aligned otherwise the aesthetic effect it will not be the wished one and the sheets might fail (total or partial fractures of sheets because the wrong adjustment of grafts), If the teeth are misaligned it is better initiates a orthodontics treatment, in this way we can ensure that the treatment will be a success.
The natural teeth will be intact as long as they have not been worn out.
Yes, it is possible to detect and treat effectively. The sheets of porcelain or resin are not a barrier to detect caries or structural anomalies in the teeth
The sheets or veneers resin or porcelain are used in order to improve the aspect of the teeth and the smile, as well as the functional part. The sheets or veneers are the aesthetic solution to structural problems of the teeth as: • Enamel or Dentine faults. • intrinsic Spots. • moderated to severe wear • Multiple caries • Multiple restorations • Correction of spaces or diastemas. • simply to have whiter and uniform teeth.
All the materials adhered to the surface of the teeth have risk of fracturing if an excessive force is generated, for example, to bite ice. today the materials and adhesive protocols have improved the properties to allow the sheets or veneers stable and lasting, also is very important the Dentist experience.
Generally there is no sensibility and if appears is temporary. The sensitive zones of natural teeth are covered by the veneers.
The materials with which the Dental Development is realized generate a few micro porosities that do not affect the integrity of the enamel. If the patient in a future wants to withdraw the sheets, these micro porosities can turn to re mineralize the enamel itself.
The functional part is compromised in 100 %, often the wears of the teeth as the years went by, generate irregular contacts and problems of the joint jaw, but in the moment in which the size is returned by the sheets, more balanced new points of contact are formed. The accomplishment of a Dental Development is recommended also in Bruxismo cases (habit of pressing strongly the top teeth with the low ones) since there is returned to the patient not only the size that has lost with the wear but new ideal contact points that prevent creaking teeth.
