Restauración de dientes anteriores primarios: Nueva técnica de aplicación clínica para la fabricación de coronas de acero cromo con frente estético
Restoration of temporary anterior teeth: a new clinical application technique for aesthetic chrome steel crowns
* Profesores de la Especialidad de Odontopediatría de la División de Estudios de Postgrado e Investigación de la Facultad de Odontología, UNAM. México.
El propósito de este trabajo fue describir una técnica estética para dientes temporales anteriores con ventajas que otras técnicas no ofrecen. Se rehabilitaron pacientes infantiles (n = 10) con un rango de edad de 2 a 4.5 años (edad promedio = 3.08 años) utilizando coronas de acero-cromo en dientes incisivos centrales y laterales superiores e inferiores (N = 22). La técnica consistió en soldar una malla metálica en la superficie vestibular de la corona; como siguiente paso se le puso ácido grabador y silano; posteriormente se colocó adhesivo, opacador y resina. Se pulieron, se les dio el terminado y se procedió a cementar en los pacientes. Resultados: Durante el seguimiento de seis meses a dos años, una corona (4.5%) se desprendió por traumatismo y las otras 21 (95.5%) permanecieron en la cavidad bucal en óptimas condiciones.
Palabras clave: Restauración; dientes anteriores temporales; coronas estéticas
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.
Key words: Restoration anterior temporary teeth; aesthetics crowns
