Today, it is quite easy, even to the unfamiliar practitioner in implantology, to get clear ideas of the surgical stage in treatments where implants are involved. These procedures have been well described and documented, especially by the swedish school. But things are less simple concerning the prosthetical procedures. After a personal experience of years, in this field, both, as oral surgeon and prosthodontist, we think time has come to point out several criterias, leading to long range success. We will review some major aspects of this particular prosthodontics, like: different clinical situations, according to the localisation of edentulism, connections, frameworks and cosmetics, and so on... We are convinced that the respect of these rules is one of the numerous keys of success in today's implantology.
