Resumen
Las prótesis dentales fijas implantosoportadas de arcada completa, una prótesis implantosoportada, que el paciente debe manejar cuidadosamente en los procedimientos de higiene bucal domiciliaria, es la alternativa fija a una prótesis soportada por mucosas o anclada a implantes. Clínicamente, la ejecución de esta rehabilitación requiere cuatro implantes para el maxilar inferior y seis implantes para el maxilar superior. El objetivo del presente estudio es verificar la tasa de supervivencia de los implantes para prótesis fijadas sobre implantes en el maxilar superior edéntulo. Este estudio retrospectivo se llevó a cabo en pacientes que recibieron prótesis fijas de arcada completa superior sobre seis implantes para rehabilitación. Se incluyeron y evaluaron desde el punto de vista clínico y radiográfico un total de 36 pacientes. El período de seguimiento en el que se recogieron los datos de la arcada completa superior es de entre 60 y 84 meses. En este período se insertaron y controlaron un total de 232 implantes. Se llevaron a cabo evaluaciones clínicas y radiográficas de los 232 implantes, con una reevaluación constante. La tasa de supervivencia total de los implantes es del 93,1%, valor similar a estudios previos ya publicados sobre el tema. Hubo pocas complicaciones protésicas, principalmente la fractura de los dientes protésicos anteriores. La mayoría de estos pacientes de arcada completa, que como antagonistas habían confeccionado previamente otras prótesis dentales fijas implantosoportadas de arcada completa o sobredentaduras de cuatro o sobredentaduras de dos implantes, logran buenos resultados en este estudio a los 84 meses.
