Used to correct small imperfections, these ceramic veneers extrafinas will be objects of debate at the CIOSP 2013. < span id = "more-12976" >
With variable thickness between 0.3 and 0.5 mm, contact lenses in China are spreading in dental offices in the country. Idealized for aesthetic purposes, these extrafinas facets are cemented on the front of the tooth without anesthesia, with little or no wear of enamel, to correct small imperfections as teeth spaced, broken, misaligned, worn and with signs of aging.
“as well as ocular contact lens is invisible to the eye, dental contact lens joins the tooth in such a way that it’s hard to detect it,” says the surgeon-dentist Victor Clavijo, master and PhD in operative dentistry from UNESP, who will speak on the topic at the CIOSP 2013, held from 31 January to 3 February by APCD-São Paulo Association of dental surgeons , at Expo Center Norte, in São Paulo, Brazil.
resistant Extra-fine the first contact lenses were developed in 1985 in the United States by the dental surgeon John r. Calamia. Problems involving the techniques and materials from adhering to teeth caused many fractures and cases of persistent gingivitis, which desestimularam the job of this restoration.
the technique was only resumed in the late 90 with the emergence of ceramics that increase resistance of the facets, such as feldspar ceramic aluminizadas and injected the dissilicate base. “Today in Brazil, the vast majority of prosthetics can do a contact lens from these ceramics,” says Victor Clavijo.
To the expert, the popularization of the technique stems from the fact that the dentists currently have more access to information about contact lenses, via the internet, courses and publications. On the other hand, patients are drawn to put a side that, in most cases, dispensing anesthesia and tooth enamel wear.
Victor Clavijo points out that the application of contact lenses is successful when obeys precise indications. “She is contraindicated for discolored teeth, very badly positioned or that are too far forward,”
argues.
treatment is done in three steps. At first, the dentist makes pictures and the molding of the patient’s teeth. In his lab, the prosthetic makes tests to assess the feasibility of installing or not the ceramic restoration. If so, the dentist performs a simulation through the technique of mock-up (maquete), allowing the patient to glimpse how your smile will be with the facet. If authorized, the surgeon-dentist makes new molding that is sent to the prosthetic for the realization of the final work.
