Two days to explore the concept of supporting an entire prosthetic arch with immediate loading on four implants to resolve clinical situations that would otherwise require more complex and expensive treatments. In this course you will learn the immediate function rehabilitation protocol based on the optimal number of four implants positioned to support a complete prosthetic arch. It takes advantage of the inclination of the two distal implants and the cantilever of up to two distal elements of the prosthesis and allows the implants to be prostheticized on the same day of surgery. An afternoon practical session led by the speaker with individual testing on an animal model allows the immediate application of the most important technical phases illustrated.
