Restauración de dientes anteriores primarios: nueva técnica de aplicación clínica para la fabricación de coronas de acero cromo con frente estético

Abstract

The purpose of this clinical investigation was to describe an aesthetic technique for temporary anterior teeth with advantages that other techniques do not offer. A clinical study was carried out with children (n = 10) with a range of age from 2 to 4.5 years (average age = 3.08 years) using stainless steel-chrome crowns in central and lateral upper and lower incisors (N = 22). A portion of metallic mesh was solded to the crowns in the labial surface, the meshwork was etched with phosphoric acid. A scotbond primer (silane) was applied. A thin coat of white masking agent and composite were applied and light cured. These veneer crowns were polished, finished and cemented. Results: During the follow-up from six months to 2 years, a veneer crown (4.5%) was lost by traumatic injury, the rest (21, 95.5%) remained in the oral cavity in ideal conditions.
