Resumen
Cuando se ha producido algún tipo de daño en una pieza dentaria, este debe ser rehabilitada para así devolver función, anatomía y lograr evitar el avance o la instauración de un nuevo daño según sea el grado de destrucción se seleccionará el material y la técnica para la rehabilitación, pudiendo ser esta una técnica directa o indirecta. La técnica de restauración indirecta utiliza materiales de distinta naturaleza con características que los hace ideales para determinadas situaciones como lo son los materiales metálicos, cerámicos y combinados. Uno de los mayores problemas de la odontología restauradora para reconstruir las partes perdidas de las estructuras dentarias duras (esmalte, dentina y cemento), es fijar a ellas la restauración. Cualquiera que sea el método o técnica de fijación del agente cementante que mantendrá unidas la restauración con la pieza dentaria, incluirá algún mecanismo de adhesión además, este agente cementante debe cumplir con una serie de requisitos y factores que favorecerán la adhesión y así asegurar el éxito de la rehabilitación en el tiempo. Así, el objetivo fundamental de este caso de estudio es determinar el protocolo para la cementación de incrustaciones de zirconio en piezas posteriores, es decir el de otorgar el mejor sellado marginal posible para que no fracase la restauración, evitando la microfiltración marginal, el desalojo de la restauración, la sensibilidad postratamiento, los problemas estéticos y caries secundaria. En nuestro paciente que presentaba una restauración de amalgama en la cual encontramos desajustes marginales y filtración cambiamos la amalgama por algo más estético como el zirconio además de utilizar como base cementante, cemento resinoso y de este procedimiento obtener un buen pronóstico para el paciente con lo biocompatible y lo estético.
When there has been some type of damage to a tooth, it must be restored in order to restore function, anatomy and achieve prevent progression or establishment of a new damage as the degree of destruction of the material and the technique to be selected the rehabilitation and may take direct or indirect technique. Indirect restoration technique uses materials of different nature with features that make them ideal for certain situations such as metal, ceramic and composite materials. One of the biggest problems of restorative dentistry to reconstruct the missing parts of the hard tooth structure (enamel, dentin and cementum), is set to restore them. Whatever the method or technique of fixing cementing agent that will keep together the restoration with the tooth, include some adhesion mechanism also this cementing agent must meet a series of requirements and factors that encourage adherence and ensure success rehabilitation in time. Thus, the main objective of this case study is to determine the protocol for cementation of inlays zirconium in later pieces, ie that of providing the best sealing marginal possible not to fail the restoration, avoiding marginal microfiltration, the eviction of restoration, post-treatment sensitivity, aesthetic problems and secondary caries. In our patient he presented an amalgam restoration in which we find marginal imbalances and filtration change the amalgam by more aesthetic and zirconium in addition to use as a cementitious base, resin cement and this procedure to obtain a good prognosis for the patient with biocompatible and the aesthetic.
