Resumen
Las carillas de porcelana son un tratamiento restaurador que ha
probado su bondad después de muchos años de uso clínico,
especialmente en el sector anterior por sus implicaciones estéticas,
con porcentajes de éxito próximos al 95% a los 15 años. El
presente trabajo de investigación hace una exposición del
tratamiento con carillas de porcelana, mediante la técnica
sistemática de la preparación y construcción e incluye las
indicaciones y contraindicaciones para su empleo, sus ventajas e
inconvenientes, el diagnóstico, la comunicación con el paciente, el
cementado de las mismas y el mantenimiento posterior. La técnica
sistemática hace referencias a la Reducción vestibular: A las 20
carillas se las preparo en la cara vestibular entre 0,5 y 0,8 mm,
con un mínimo de 0,3 mm, con una piedra diamantada
troncónica de extremos redondeados, de grano grueso, de longitud
y calibre adecuados. Reducción proximal: se extendió hacia
palatino/lingual hasta las zonas no visibles del diente. El perfilado
y acabado de esta reducción proximal es en chaflán curvo o
Chánfer realizado con el extremo redondeado de la piedra
diamantada tronco-cónica procurando que el ángulo que se forme
con la cara proximal sea igual o mayor de 90º. Reducción Incisal:
se biselo toda la anchura del borde incisal contorneando
ligeramente el mismo, de tal modo que el aspecto final del borde
incisal es de chaflán curvo que se prolonga sin solución de
continuidad con el margen de las caras proximales. Es necesario
evaluar la personalidad y actitud del paciente junto con sus
expectativas de resultados, como elemento necesario para el éxito
del tratamiento. Un paciente cuyas expectativas sean poco
realistas, o que presente una situación dentaria que no pueda ser
suficientemente mejorada con carillas, será una contraindicación
para este tipo de tratamiento
Porcelain veneers are a restorative treatment that has proven its goodness after many years of clinical use, especially in the front of its aesthetic implications, with success rates close to 95% at 15 years. This research makes an exhibition of porcelain veneers treatment through systematic technical preparation and construction and includes the indications and contraindications for use, their advantages and disadvantages, diagnosis, communication with the patient, cemented of these and subsequent maintenance. The systematic technique makes reference to vestibular Reduction: In the 20 pages is the prepared on the buckle surface between 0.5 and 0.8 mm, with a minimum of 0.3 mm, with a diamond stone stump rounded end of coarse-grained length and suitable caliber. Reduced proximal spread palatal / lingual areas not visible to the tooth. The shaping and finishing of this reduction is proximal bevelling or no wrapping made with the rounded end of the trunk-conical diamond stone ensuring that the angle formed with the proximal surface is equal to or greater than 90 º. Incisal reduction: it cannot entire width of the incisal edge slightly outlining it, so that the final appearance of the incisal edge is curved chamfer that extends seamlessly with the margin of the proximal surfaces. It is necessary to evaluate the patient's personality and attitude along with their expected results, as necessary for successful treatment. A patient whose expectations are unrealistic, or submit a dental situation that can not be sufficiently improved with veneers, is a contraindication to this treatment
