<p>In this pair of dental trays (10, 11) defining a median plane (P) and a transverse plane, comprising two lateral pivots (33) on each tray (10, 11) designed to articulate the ends (22) of two substantially rigid connecting rods (20) arranged in a vestibular position and laterally connecting a pivot (33) of one tray (10) to a pivot (33) of the other tray (11), and in which the pivots (33) are perpendicular to the median plane (P) on each tray (10, 11), each pivot (33) has means (36) for elastic snap-fitting of the ends of connecting rods (20), holding the connecting rods at a distance from the trays.</p> |
