1. A device for determining an acclusal plane for teeth positioning in detal prostheses, comprisingtwo first members pivotable about vertical axes in a first plane which can be aligned with an ear-nose plane of a patient;
- a second member vertically adjustable relative to said first members and therefore said first plane so as to be brought in contact with plastic material on a base plate placed on an occlusal surface of remaining teeth or placed in correspondence with a lip line, said second member being movable parallel to said first members so that upon said contact said second member determines a position of a required occlusal surface;
means for moving said second member relative to said first members and including an adjusting element manually movable by a user;
a holding body, said first members being arranged pivotally relative to said holding body, said second member being arranged vertically displaceable relative to said holding body and having two pins;
two pivot pins each defining a respective one of said axes of pivoting of said first members,said holding body having two guiding openings in which said pins of said second member are vertically movably, said holding body further having two further guiding openings in which said pivot pins are turnably received, said first mentioned guiding openings being coaxial with said second mentioned guiding openings.
