Resumen
Objetivo: Este trabajo tuvo como objetivo presentar un método de tratamiento quirúrgico basado en la técnica All on Four realizado en el curso de especialización en implantología de la Universidad Federal Fluminense. Detalles del caso: La atrofia alveolar en maxilares edéntulos dificulta la rehabilitación total de las arcadas, especialmente en la rehabilitación con implantes dentales osteointegrados, que requiere suficiente cantidad de hueso o cirugía previa para ganar hueso, aumentando la morbilidad y complicaciones del paciente. Por ello, han surgido técnicas para evitar estas zonas de mayor pérdida ósea y sortear estructuras nobles, que muchas veces son limitantes para la instalación de implantes. Una de las técnicas sugeridas y bien aceptadas para evitar estas estructuras anatómicas es el concepto “All on Four”, donde se instalan cuatro implantes largos, dos anteriores se instalan axialmente y los posteriores se colocan en posición angulada para una mejor distribución anteroposterior, así como la variación de esta técnica que se presenta en detalle en este artículo. Consideraciones finales: Considerando la importancia de la rehabilitación total con implantes, utilizando técnicas dirigidas a la instalación de implantes en maxilares atróficos, corresponde a profesionales experimentados utilizar esta técnica o variantes de la técnica, de manera cautelosa y con base científica, para que la rehabilitación traiga las ventajas reportadas en este artículo.
