DEVICE FOR TRAINING JAWS Russian patent published in 1997 - IPC

FIELD: medical engineering. SUBSTANCE: device has two branches curved to form semicircles (the superior one and the inferior one) joined at their ends by means of hinges. The branches are connected to cantilevers having removably mounted spoons in the middle part. Each spoon has groove-shaped operating part curved to correspond to the shape of jaw and stem with fastening spring member engageable with the corresponding window made in the cantilever. The operating part of a spoon is in the concave part of a branch and enclosed into rubber envelope. The upper branch cantilever is rigidly connected to a handle, the lower branch cantilever is attached to an arc with fixing member. The second handle is fixed on the arc and scale divisions are produced to determine the angle contained by the branches. To provide an arc moving upon opening branches, a through opening of the corresponding form is produced in the upper branch cantilever. EFFECT: enhanced effectiveness of mechanotherapy treatment; uniform load distribution over teeth.
