The invention concerns a method for making a bridge and a device forming a set of elements or kit for implementing said method. The set comprises at least one crosspiece (2) including at least at one of its ends (13) fixing elements (5) for anchoring it in the teeth (3, 4) forming the pillars of the bridge (1), thereby constituting an I-shaped frame. The set may comprise an articulation element at the end or at the middle of the crosspiece for receiving a pivot element to form an L-shaped or T-shaped frame. Preferably the crosspieces have lateral trapezoid denticulations. The roughness of the surface results from photo-etching a screen with acid.
L'invention concerne un procédé de fabrication d'un bridge et un dispositif formant un ensemble d'éléments ou trousse pour appliquer ledit procédé. L'ensemble comprend au moins une traverse (2) qui comporte au moins à ses extrémités (13) des éléments de fixation (5) pour son ancrage dans les dents (3, 4) formant les piliers du bridge (1), constituant ainsi une armature en I. L'ensemble peut comporter un élément d'articulation à l'extrémité ou au milieu d'une traverse apte à recevoir un élément pivot pour former une armature en L ou en T. De préférence les traverses présentent latéralement des dentelures trapézoïdales. La rugosité des faces est obtenue par photogravure à l'acide d'un tramé.
