Ceramic veneers: what it is, before and after photos

The urgency of the presence of healthy teeth, which guarantee a beautiful smile, is beyond doubt.This factor gradually strengthens the importance of achieving success in the professional and social spheres.Modern dentistry offers an effective technique for leveling many defects of teeth, applying different types of veneers, which are thin plates, fixed to a special adhesive composition.

Veneers: some concepts

Amazing designs have been made available that give an excellent smile, thanks to Hollywood.A simple technology of masking tooth surfaces with an amazing result was given its name from the term "veneer", translated from English, meaning "facing".This figurative name accurately reflects the basic essence of the whole algorithm of the operations performed on the manufacture of veneers and subsequent installation.

The problem, which is better - veneers or crowns, solves the specialist for a detailed examination of the oral cavity.If he chooses in favor of the first option, this will mean a minimum of preliminary preparation of dental tissues for gluing a thin plate.

Types of veneers: an overview of materials and installation techniques

The installation of a particular variety of veneers can not be focused solely on the wishes of the patient, as each of them has specific indications determined only by an experienced physician.

In the arsenal of specialists on the use of composite plates, there are two ways to produce them:

direct - directly being at the reception of the dentist, with only one visit;
indirect or delayed - involves the removal of the impression and work in the laboratory for the manufacture of veneer dental technician.

An attractive circumstance is that a small layer is grinding off.The fillings, which are directly packed in the cabinet, serve with proper care for almost five years.More often this method improves the aesthetics of one, two teeth.Laboratory microprosthes pass the stage of polymerization in special furnaces, therefore they are stronger than veneers straight, not passing such a high-temperature treatment.

As far as a person changes and becomes younger after he has installed ceramic veneers, the photo allows you to see with a high degree of certainty.They are done in a laboratory way by casting a tooth previously dentured by the dentist.The manufacturing time takes several days, so the patient is usually fixed temporary plastic plates on the prepared surface.

The production process in the laboratory can take place according to one of three technologies:

classical - in the form of sequential layering of ceramic powder with firing;
press ceramics - injection molding technique;
milling from the block according to the exact tooth model prepared with the help of the computer program.

Finished plates with special dyes are given to the shade chosen at inspection.At the repeated admission the dentist fixes the veneers on the desired site.Ceramics makes it possible to restore the splendor of several surfaces, guaranteeing them a long-term preservation.

Unique zirconium veneers have an amazing cosmetic effect, thanks to the amazing strength of the material.They have both biological compatibility, allowing to avoid possible complications after the procedure.Rare application is due to the complexity of processing and high price.

Lumineers, common in Hollywood circles, this in its role function - veneers without turning teeth, which are glued immediately to the surface, thanks to an exceptionally small thickness.They are quickly put and, if necessary, do not require special efforts for removal.

The snow-white glow of a smile practically does not fade for a long time, which causes the gradual expansion of the scope of application of this variety.

Advantages and possible disadvantages

Some concerns are caused by the restoration of teeth with veneers, seeming expensive and inaccessible technology.Meanwhile, analyzing the various materials used to make them, you can make a choice, focusing on your own preferences and financial opportunities.

The most budgetary option is composite veneer, among which the advantages are rapid production and a small percentage of grinding of surface dental tissues.They are quite fragile, faster erase and lose shine, requiring regular polishing.The period of their impeccable service( 3 ÷ 9 years) is largely due to the observance of personal hygiene rules, and also depends on the degree of functional load.It is advisable to take into account that this material is susceptible to the effect of alcohol-containing compounds.

It is necessary to know when placing a ceramic veneer that this is a more expensive option, but they are more durable, durable and perfectly preserve the exterior gloss without changing the shade.

Advantages of different types of veneers:

the ability to select the desired shade that fully imitates natural teeth;
duration of whiteness preservation without turbidity and staining;
correction of an extensive list of defects;
gentle grinding for thin plates;
possibility after loss of decorative qualities of replacement of plates from composite mixtures;
no sense of foreign matter after installation, causing discomfort.

Disadvantages:

impossibility to disguise a significant darkening of the tooth surfaces;
prohibition to carry out restoration if a gum disease is diagnosed;
contraindication is the absence of a significant percentage of the tooth as a result of the cleavage, as well as its weakened state.

Before finding a "Hollywood smile" it is necessary to understand that over time even the most durable veneers will require replacement and they will need to be worn for life.Therefore, the question of how much it costs to put veneers for teeth, takes into account the variety of indicators of their effectiveness.

Selection of restoration method

The decision that is preferred - veneers or crowns on the front teeth, the doctor takes after determining the degree of their destruction.Usually the indications for using the first, more modern and sparing reception, are the preservation of more than fifty percent of dental tissues.Otherwise, you will need to fix a traditional and reliable crown.The same decision by the doctor will be made in the presence of extensive caries and multiple cracks.He will give advice on how to take care of the veneers, so as not to lose his newfound beauty.

Fastening of veneers on teeth

Veneers allow to level an extensive list of problems:

age or nicotine loss of teeth by external appeal;
irregular congenital form;
need to disguise the unaesthetic look of the crown;
hypoplasia - underdevelopment of teeth;
marked abrasion of the enamel;
small chips;
is a serious diastema, a dentition between adjacent teeth;
deformation after injury;
pigmentation for various reasons - fluorosis, tetracycline teeth;
pronounced discrepancy in the dimensions of dental planes and bite;
some turn of the tooth relative to the vertical axis;
gum smile or a gingival smile;
seals that are different in color;
uneven contour line of the neck of the teeth.

Preliminary tooth preparation

Almost all the techniques for restoring tooth surfaces include the preparatory stage - preparation for veneers with a certain algorithm of action.

Grinding of the vestibular surface with a diamond calibration boron with the formation of a gutter near the gum to protect its tissues.
Turning of approximal - adjoining to adjacent teeth, planes.
Preparation for the desired depth of the cutting edge.
If necessary, the palatal surface is treated.

At the final stage, the doctor removes the remaining sharp protrusions using finely dispersed boron.This will avoid the occurrence of stress concentration sites leading to deformation and cracking of the veneer.

The preparation technique for its intensity has its own peculiarities due to the type of defect to be removed.

On the turned teeth, the protruding areas are reduced, from which more enamel is grinded off than from other surfaces.
If the diastema is to be closed, the degree of treatment depends on the gap size.
Curved abnormal teeth require a sufficiently large volume of preparation, at which the outer protrusion is grasped until it coincides with the entire dental arch, followed by polishing the entire surface to the gum.

Direct veneers: algorithm and manufacturing features

Composite lamellae created directly on the teeth( straight veneers) are installed mainly in the frontal plane, the so-called smile zone, which does not bear such enormous loads as lateral chewing areas.

Preliminary grinding of the anterior - vestibular tooth surface to a depth of 0.5 mm before layering of the composite material allows a good natural effect to be achieved.How do composite veneers look, the photo before and after allows you to objectively assess the result achieved.In the case of failure of the preparatory failure, the patches are made of an opaque composite with an unnaturally white hue.

To create a barrier between the tissues of the oral cavity and the site where the restoration operation is performed, a cofferdam is used - a special latex plate.According to the structure, the materials used are identical to the filling compositions, in which an inorganic filler and silane are added to the base organic matrix( resins - epoxy, acrylic).It is advisable to select such varieties that are well and easily polished and have color stability( the particle size is indicated in μm):

mini-filled composites( 1 ÷ 5);
hybrids( 0,01 ÷ 8);
nanocomposites( 0.004 ÷ 3).

They all have the ability to achieve normative hardness in the light.

Leveling of the tooth curves

Dystopia or abnormal anomalous tooth position of different degrees is present in almost 95% of the world's population.If a significant bias is revealed, then a person may have a choice problem, which is better to establish for alignment - veneers or braces according to the doctor's recommendations and own preferences.

Depends on the alignment method mainly from a competent assessment of the situation by the doctor.Of course, if the displacement has become significant, it is necessary to resort to braces.In other cases, you should consult, as do veneers on crooked teeth, to ensure a quick result.Lining is made taking into account the revealed defects, leveling the whole row.
