Many patients are involved in their appearance being changed. Porcelain veneers are one choice. The removal of less tooth structure than for a crown requires this. The final appliance in a crown protects the entire tooth. The front part of the tooth and a small amount of the biting edge are only hidden by a veneer. It does have benefits and drawbacks. The primary benefits are the fact that less tooth structure is removed and they look very aesthetic.Learn more by visiting Des Moines Teeth Whitening
As not all teeth are well suited for veneers, a downside would be on a person basis. Before a veneer is considered, for instance, a person should be an adult. Cases of a dentist putting veneers on younger people have been published. In such situations, the teeth may not completely erupt and an unsightly line will reveal the margins in time. Orthodontics may have a better effect in many younger patients as well. The inflated expectations of a patient can be a consideration that is a sign to a dentist who may not perform the veneer procedure. Patients that have a heavy bite do not have veneers put on them. That is that in closing, the front teeth are always in strong contact. The veneers can break or chip easily in such cases.
When an individual is picked, the procedure is actually quite satisfactory for veneers on good clinical grounds. In most cases, the teeth are minimally reduced by 1 -1.5 mm. The reduction could be more to allow for a final positioning of veneers that aesthetically match up if a tooth is out of line with the next one to it. The impression is collected and the case is sent to the lab. Temporary declines are not necessarily suggested due to small reductions.
The laboratory makes the veneers of porcelain and schedules the shade with the dentist. In certain situations, a dark tooth or teeth will cover the veneers so that the veneer can be less transparent. In cases where the underlying tooth color is natural, it is possible to create a more transparent veneer. When the veneers are returned to the dentist there are many steps which are followed. When veneers were first made in the late 1930s, they did not stick well to the structure of the tooth, so they were only a temporary measure. In the 1980s, new techniques were developed to allow the veneer to conform to the structure of the tooth. The veneer inside is ‘etched’ with hydrofluoric acid first. This is a sort of acid that can etch glass, which is a type of porcelain. For about a minute, it is etched and then washed with water. Then orthophosphoric solvent, a milder acid, is used to clean the etched material within the veneer. The strong hydrofluoric acid is neutralized by this step. The veneer is then rinsed again at this point. A drying solution, typically an acetate solution, is then used to remove any water from the inside portion of the veneer. A relatively new material, Propanone, is used at this point. The brand name of the one I use is Den-Mat-s Link Bond. The interior of the veneer is painted with it. It is a chemical of a polymer with a branch that can bond to the porcelain. This is lightly dried and the veneer on the tooth is ready to be put.
