Resumen
La corona Jacket de porcelana, es la restauración más estética
para la duplicación de dientes anteriores individuales cuyas
características son el empleo de un hombro recto para que
proporcione una adecuada resistencia a la fractura, así como un
buen acabado estético. Además la localización del margen
siempre será Supragingival no sólo porque permite al paciente
una mejor higiene, sino porque es conveniente evitar la humedad
al cementar este tipo de corona. Asimismo siendo Supragingival
logramos dar un efecto estético adecuado realizando un
pincelado sobre el margen al momento de cementar de tal
manera que volvemos invisible el límite corona-restauración
gracias al cemento dual. Durante la preparación de la línea de
terminación han de perseguirse una serie de objetivos que
aseguran la durabilidad de la restauración, entre ellos tenemos:
proporcionar suficiente resistencia para soportar la deformación
durante la función, no dejar prismas de esmalte sin soporte, la
decisión se debe tomar teniendo en consideración la cantidad de
diente destruido y la necesidad de cambiar la oclusión de los
dientes a tratar o no, cuanto mayor sea el grado de destrucción
mayor tendencia se tendrá a proteger el diente con una corona de
recubrimiento total. Por el contrario, cuanto menor sea su grado
de deterioro, mayores posibilidades tendremos de un tratamiento
más conservador con las facetas de cerámica, si nos
encontraremos a menudo con situaciones en el que el tratamiento
de un sector antero-superior no permite mantener la morfología
palatina por necesidad de crear o mejorar la guía anterior o
canina, dependiendo de la zona donde ocluyan los bordes
incisales inferiores, se requerirá la utilización de coronas Jacket.
Porcelain Jacket Crown, is the most aesthetic restoration for anterior teeth duplication of individual characteristics are the use of a straight man to provide adequate resistance to fracture, and a good aesthetic finish. Also the location of the margin will always be Supragingival not only because it allows the patient a better hygiene, but because it is desirable to avoid moisture to this type of crown cementation. Also we still Supragingival right to an aesthetic effect by a brush on the margin at the time of cement so as to become invisible boundary-restoration crown thanks to dual cement. In preparation for the finishing line must be pursued a series of objectives that ensure the durability of the restoration, among them are: to provide sufficient strength to withstand deformation during function and does not leave unsupported enamel prisms, the decision should be made taking into consideration the amount of tooth destruction and the need to change the occlusion of the teeth to be treated or not, the greater the degree of destruction will have a greater tendency to protect the tooth with a crown of full coverage. By contrast, the lower the degree of impairment, the greater chance we have of a more conservative aspects of ceramics, if we often find situations in which the treatment of anterior superior sector keeps no palatal morphology necessity of creating or improving previous guidance or canine, depending on the area where the lower incisal edges occluding will require the use of crowns Jacket.
