摘要：Objectives: Comparative study, that permitted the evaluation of the clinical behavior of two types of esthetics veneers. The comparison patterns were: esthetic functional advantages, cost and degree of patient's satisfaction. Materials and Methods: The sample was chosen conveniently and was made up of 30 (thirty) individuals, the teeth included upper and lower, central tocanine; preparation included a chamfer, labial enamel reduction 0.3 to 0.7 mm, and incisal edge coverage, for both preparation veneers. A single laboratory technician fabricated the feldspathic's veneers on refractory dies. Internal sur faces were etched with 5% hydrofluoric acid and silanated; all veneers were bonded with light activated resincement (Vario link I). The direct resin veneers had the same preparation and were made of mi crohybrids composite resin, the enamel was etched with 35% phosphoricacid gel, and bonding agent was placed. The incremental technique was used for the resin veneers, and ultra dent system for polishing. Results: The composite veneers and porcelain veneers, no significant differences between them were found. Conclusions: Esthetics resin veneers can be considered as a good prosthetic alternative, in teeth that requires recuperate their esthetic and function.
其他摘要：Objetivos: Realizar estudio comparativo para evaluar el comportamiento clínico de dos carillas estéticas, tomando como patrones de comparación; las ventajas estético funcionales, costo y grado de satisfacción del paciente. Materiales y Métodos: Se seleccionaron a conveniencia 30 pacientes, tomando como unidad de muestreo incisivos y caninos superiores e inferiores. La técnica de preparación del diente, contempla margen cervical tipo chamfer, reducción labial del esmalte de 0.3 a 0.7mm con cobertura del borde incisal para ambos tipos de carillas. Un solo técnico de laboratorio fabricó las carillas de feldespato, sobre troqueles refractarios. La superficie interna de la carilla se grabo con ácido fluorhídrico al 5% y luego silanizada, se cementaron con cementos resinosos (Vario link I). Las carillas directas de resina tienen la misma preparación dentaria y fueron hechas de resina compuesta microhíbrida, se hizo grabado con ácido fosfórico al 35%, y se colocó agente de unión. Para la resina, se utilizó la técnica incremental y para el pulido el sistema ultradent. Resultados: Las carillas de resinano presenta diferencias significativas con la de porcelana Conclusión: Las carillas de resina constituyen alternativa de tratamiento protésico, en dientes que requieren recuperar estética y función.
