<p>The device (1) has a materializing and positioning unit perpendicular to vertical columns (21) of a frame (2) and slid for being aligned with a patient pupil line, where the unit is formed of a rib (3) e.g. rod made of Plexiglas(RTM: acrylic plastic sheet), an adjusting unit (4), grooves (5), graduations (6a, 6b) and a median vertical line (7). A rectilinear lateral rod (15) aligns a camper line on a human face profile, and is fixed on the columns. The rod is placed parallel to the camper line by pivoting the frame around a cross piece (22) on which a bite fork (11) is mounted.</p> |
