Abstract
The objective of this work is to review the prosthetic particularities of complete implant-supported rehabilitation. Indeed, conical internal connection abutments are the reference abutments for totally edentulous patients. They allow the masticatory forces to be disturbed and reduce the micro-movements generated at the interfaces with the implants. An accurate impression provides a passive fit that is essential for successful treatment. The choice of the direct open pick-up technique is specific to totally edentulous patients. The splinting connection of the transfers provides a higher degree of precision, particularly if the implants have divergent axes. It is recommended to design the complete arch bridge in segments of three or four elements to ensure the passivity of the framework. At the anterior level, it is essential that the implant axis be compatible with the prosthetic axis to obtain the appropriate emergence profile. The main objective is to obtain a passive adaptation of each abutment on each corresponding implant.
