Resumen
El presente estudio experimental in vitro compara mediante el uso de un rugosímetro (Surftest - III, Mitutoyo), la rugosidad superficial de porcelana feldespática abrasionada y después pulida, usando diferentes procedimientos con instrumentos intraorales como fresa diamantada grano fino, kits de pulido y pastas diamantadas de diferente granulación. Para el grupo control, las muestras fueron glaseadas y luego pulidas usando instrumentos extraorales en un laboratorio dental. Se realizaron pruebas estadísticas ANOVA y de comparación múltiple. Los resultados indican que una combinación adecuada de una fresa de diamante grano fino, las 3 gomas del kit Porcelain Polishing (Jota) y las pastas diamantadas Diamond Polish (Ultradent) de 1 pm y de 0,5 pm, usados en ese orden producen una menor rugosidad superficial en las muestras. Estos hallazgos son importantes ya que indican como alternativa, el pulido intraoral, después de abrasionar una restauración cerámica.
