Resumen
It is necessary to generate more evidence on the outcome of contemporary protocols for full-arch rehabilitations supported by implants in immediate function in areas with limited quantity and density bone.
This research project aims to investigate the outcome of fixed prosthetic restorations supported by implants in immediate function for full-arch rehabilitation through the All-on-4 concept contemporary protocol, s...
Mostrar másDescripción detallada
Problem The fixed prosthetic rehabilitation through implants in immediate function is documented without prejudice of the outcome when compared to 2-stage surgery.1 One of the protocols for full-arch fixed prosthetic rehabilitation supported by implants in immediate function is the All-on-Four concept, which is documented with good long-term outcomes in both jaws.
Nevertheless, the protocols suffered a constant evol...
