Resumo
Objetivos. 1) Evaluar el rendimiento clínico de las restauraciones posteriores de oro, durante 44 años; 2) Analizar su indicación y distribución, en relación con la evolución de la evidencia científica. Materiales y Métodos. En 100 pacientes, se estudiaron 656 restauraciones posteriores de oro colado. De 2552 pacientes registrados, 210 cumplieron los requisitos de inclusión. La muestra estadística representativa fue de 136 pacientes. Se seleccionaron al azar 140 y se estudiaron 138. Doce variables fueron analizadas. El procesamiento de datos se realizó con el software Epidat, versión 3.1 y del software SPSS versión 13.0. Resultados. Estaban en función 536 (81.7%) y 120 (18.3%) fracasaron. Según el Método de Kaplan-Meier, la sobrevida total estimada fue de 77.4% a los 39 años y 10 meses. Conclusiones. La constante actualización del conocimiento, responsabilidad ética del profesional, le permitirá introducir los cambios conceptuales y clínicos a la luz de las nuevas evidencias científicas.
