Resumen
En la presente investigación se analizará la historia de las restauraciones indirectas con coronas de disilicato de litio, sus características, indicaciones, desventajas, así mismo los materiales que se han utilizado a lo largo de los años hasta llegar a las restauraciones indirectas, los cuales son unos de los sistemas cerámicos con propiedades de excelencia y confiables para el rehabilitador oral. El objetivo de esta investigación es determinar la eficacia de las coronas de disilicato de litio. Así se menciona las propiedades de la cerámica a base disilicato de litio que poseen cualidades de excelencia, debido a la estética funcionabilidad y resistencia que representa frente a las fuerzas masticatorias. Posteriormente este tipo de cerámica que se utilizara en este estudio será el sistema cerámico IPS e. Max de la casa Ivoclar Vivadent. Para recolectar datos confiables se realizará un caso clínico en el que se tratara un incisivo lateral superior derecho no vital, en el que se realizaran todos lo procedimiento adecuados empezando con la apertura del conducto, reducción de la gutapercha, cementación con el poste de fibra de vidrio, tallado o preparación del muñón, tratamiento de superficie para la cementación con coronas de disilicato de litio. Los estudios muestran que la cerámica a base de disilicato son una excelente alternativa porque tienen una resistencia mayor que a una restauración directa, presentan características fiables que benefician al paciente como: cualidades mecánicas óptimas, reproduce un aspecto natural similar a un diente, mayor estética, resistencia a la compresión y longevidad.
XI ABSTRACT This research analyzes the history of indirect restorations with lithium disilicate crowns, their characteristics, indications, disadvantages, as well as the materials that have been used over the years to reach indirect restorations, which are one of the ceramic systems with excellent and reliable properties for the oral rehabilitator. The objective of this investigation is to determine the efficacy of lithium disilicate crowns. Thus the properties of lithium disilicate-based ceramics that have qualities of excellence are mentioned, due to the aesthetics functionality and resistance that it represents against the masticatory forces. Subsequently, this type of ceramics that is used in this study is the IPS e.Max ceramic system of the Ivoclar Vivadent house. In order to collect reliable data, a clinical case is carried out in which a non-vital right upper lateral instinctive is treated. Subsequently, all the appropriate procedures are performed by starting with the opening of the root canal, reduction of the gutta-percha points, cementing with the fiber post of glass, carving or preparation of the stump, and surface treatment for cementing with lithium disilicate crowns. Studies show that ceramics based on disilicate are an excellent alternative because they have a greater resistance than direct restoration; moreover, ceramics have reliable characteristics that benefit the patient such as: optimal mechanical qualities, natural tooth appearance, greater aesthetics, and resistance to compression and longevity.
