The invention relates to a modular metal frame for producing a dental prosthesis. It is essentially characterized in that it consists of at least one module (1) which connects two abutments, abutments or implants (21) and (22), opposite and which combines: -two elements (11) and ( 12) each comprising an annular portion (111, 121) adapted to position itself, encircling it, on each abutment, abutment or implant (21, 22) facing each other and a longitudinal portion (112, 122) consisting of at least one rod which is secured to the corresponding annular portion (111, 121)； b) a third ring-shaped element (13) configured and dimensioned to house the rods (112) and (122) of said two elements (11) and (12), mounted in opposition, so as to keep them in contact with each other from one another and allow them to slide until the annular portions (111) and (121) of said elements (11) and (12) are interlocked respectively on the two abutments, abutments or implants (21) and (22) opposite. It is also characterized in that any extension of the metal frame is achieved by the addition of a new module (1) which connects one of the abutments, abutments or implants (21) and (22) previous to any new stump, abutment or implant (23,24), the whole being stiffened by welding points (41, 42). L'invention concerne une armature métallique modulaire pour la réalisation d'une prothèse dentaire. Elle se caractérise essentiellement en ce qu'elle est constituée d'au moins un module (1) qui relie deux moignons, piliers ou implants (21) et (22), en regard et qui associe : -deux éléments (11) et (12) qui comportent, chacun, une partie annulaire (111,121) conçue pour se positionner, en l'encerclant, sur chaque moignon, pilier ou implant (21,22) en regard et une partie longitudinale (112,122) constituée d'au moins une tige qui est solidarisée à la partie annulaire (111,121) correspondante ； b) un troisième élément (13), en forme de bague, configuré et dimensionné pour l
