Rehabilitation of total maxillary edentulism by the fixed supra-implant prosthesis

The rehabilitation of total maxillary edentulism has always been a challenge for the practitioner.  Different therapeutic alternatives are available to the dentist: from the conventional total prosthesis to the total supra-implant fixed rehabilitation. This last alternative remains by far the best aesthetically and functionally. The choice of the location of the implants is important. After osteointegration of the implants, the prosthetic steps must be respected starting from the choice of the mode of connection between implant and prosthesis which can be sealed or screwed to the adjustment of the occlusion according to the occlusal concept which depends on the antagonistic arch. All these points are to be presented in this work through clinical cases.
