Is There a Difference in the Resonance Frequency Values Obtained Directly on the Implants and Abutments

El objetivo fue evaluar las diferencias del coeficiente de estabilidad de implantes comparando los de conexion de hexagono externo (HE) y cono morse (CM). El estudio tuvo un diseno de boca dividida, siendo compuesta por 10 pacientes que recibieron protocolos protesicos de tipo hibrido. En total, 40 implantes (3,75x13 mm) fueron instalados: en el lado derecho, 20 implantes de hexagono externo y en el lado izquierdo, 20 implantes de cono morse. Despues de dos anos en funcion, la prueba de estabilidad fue aplicada utilizando una maquina MRI, Ostell ISQ directamente sobre los implantes y pilares. Considerando las medidas en los implantes, hubo diferencias entre los implantes HE y CM en mesial (p= 0,011), lingual (p= 0,003) y distal (p= 0,006). Considerando las medidas en los pilares, hubo diferenciasentre HE y CM en el sector bucal (p= 0,020) y lingual (p= 0,004). Los valores mas altos se obtuvieron en CM; los valores de las conexion tipo cono morse presentaron mayor estabilidad al comparase con los implantes de conexion de hexagono externo.
