The invention relates to a dual fixation system for dental implant prosthesis consisting of: an intermediate abutment assembly for fixation on the implant (FIG.6), clip fixation device (FIG.3), fixation screw (FIG.4) and cylinder (FIG.1) that allows the prosthesis to be screwed or retained by clip as appropriate, individually or independently for each implant.This system facilitates both the immediate loading technique and the execution of the definitive prosthesis made on an intermediate abutment, since retention by clip is very advantageous in the case of implants with unfavorable emergencies, joining them to the structure as abutments and without compromising the esthetics of the case.
