The two solutions are equally good. Both give excellent aesthetic results and serve to eat sandwiches and apples to bite without risking setback.
To decide for one or another solution depends on various factors we will try to discuss here, but first of all I must say that the veneers can be of two types:. Of porcelain or composite
The veneers and crown, which are usually also of porcelain, are very similar: both are made in a laboratory and the dentist simply put in place, cementandolas with suitable adhesive. The composite veneers, however, are something else entirely, because the manufactures directly on the tooth the dentist himself, without the laboratory involved at all in the process.
Let's see what each of these three solutions with their advantages and drawbacks:
CORONAS ( OR CASES )
They are restorations that cover the entire tooth. To place the tooth should be carved to fray stump into shape.
The laboratory is responsible for manufacturing the crown to fit the stump and when this list is cemented on. They are usually manufactured in china, with or without metal frame.
- They are very experienced restorations since, although they have evolved, bearing more than one century utilizing an.
- Porcelain never changes color and is very resistant to wear.
- You may break, but it is not very common.
- The dentist need not be a specialist in aesthetics, since the final appearance of the crown depends on the laboratory work, and clinical merely cemented in place. If the lab is good, it will also crown.
- It is a very aggressive technique, since it forces severely cut the tooth, which, as is not able to regenerate lost parts, is carved for life.
- The aesthetic aspect is entirely in the hands of the laboratory. If, upon receipt, does not meet the expectations of the patient needs to be returned for the repeat, which multiplies the necessary sessions.
- The porcelain can not be repaired or retouched. Any damage or fracture, or modification, for any reason, you wish to make passes necessarily eliminate the crown and order a new one.
A veneer is like a half-crown, since no completely surrounds the tooth, but only covers the front face, ie, the visible. As in the case of the crowns should be carved tooth, then the lab manufactures dental veneer and the cemented in place.
- You have to carve the tooth unless to put a crown, being, therefore, a less mutilating technique.
- The porcelain does not change color and is very resistant to wear, veneers are even more fragile than crowns and fractures are possible.
- The dentist also requires great preparation in aesthetics, since the result depends mainly on the laboratory. However, cementation of the veneers is a meticulous technique that can not be left to anyone.
- It is a less invasive technique than crowns, but the cut is still necessary, and is irreversible. Even the«» veneers without carving;lately proposed tooth wear require a greater or lesser extent.
- A veneer can detach or break. In the former case, it can be normally re- cementing. In the second, we will have to delete it and make a new one.
- Although porcelain does not change color, often stained margins over the years, affecting the aesthetic.
- Because porcelain can not repair or retouch any repair or modification involves necessarily remove the veneer and order another.
Composites for dental use are formed by spray porcelain and linked with a synthetic resin material, which allows directly fraguarlos mouth with the help of a special light. They adhere to the tooth without carve, and the dentist will apply and modeling material, which comes in paste form in different layers to get the shape, color and naturalness desired.
- The main advantage of this technique is its safety. The tooth suffers nothing and not have to experience a permanent loss of integrity. In fact, in most cases not even requiring anesthesia. The restoration is simply attached to the tooth, which, under the composite, remains as it was before you started.
- Unlike porcelain, composites can retouch or repair directly into mouth without redoing all the work. Any deterioration or malfunction or any modification can be solved, usually in a short time and easily.
- With proper care and some occasional touch composite restorations in good condition can last indefinitely. In our experience, the oldest restorations have exceeded thirty years of stay in the mouth a long time.
- The color stability of composites is lower than that of porcelain and, over the years, may tend to obscure
- Also, as porcelain veneers, can suffer a fracture. Of course this can be solved easily without changing the whole restoration.
- As the veneers not manufactures laboratory, but the dentist, this should have a solid training in dental esthetics and a minimum artistic skill, since everything depends on the.

Drive: For resistance, crowns keychain identified himself with aggressive oral habits: bruxism, tighteners, teethers pens, sports… And will also be an option valid on teeth that were already cut at the time to crowns, or severely damaged teeth or restored, where the cut is not going to especially aggravate the situation.
Porcelain Veneers: They are a good solution for those who want a restoration of that can be forgotten until you change them, they do not need maintenance or rather not admit. Their average duration becomes ten to fifteen years;After that time, the degradation of margins, possible fractures, changes in position of the gum and other factors often make desirable their replacement.
Composite veneers: composite veneers are the best solution for those who want to improve their smile without seeing cut his teeth for patients who may wish undecided modifications or alterations subsequent to young patients whose growth compels be adapted restorations instead of changing them through several times until the development is completed, for those who prefer to receive a reversible treatment that allows return to the previous situation if a good day decides to become another thing…
All solutions are therefore equally valid. The choice of one or the other will depend on the priorities and preferences of the patient and of course your dentist, who will prefer to use the best technique to master and, in his hands, can provide better results. Of course, it should be in the hands of someone whose training record us, and wary of balances. A clumsy or hasty work, cheap as it is, it always costs more than it's worth.
