such devices involve a wide variety of more or less 40
?xed mechanical interlocks for correcting mis
alignment of individual teeth and the two dental
arches generally. The present invention is novel
in the emphasis which is placed on the psycho
logical aspect of the subject by reason of its use.
Exhaustive tests have shown that use of the de
vice of my invention exerts a surprising influence
on patients in a way that can only be ascribed to
the psychological effect of the presence of the de
vice in the mouth of a user.
Stated in one way, in the prior art the ap
proach to the problem has been made from a
purely physiological analysis of the abnormal
dental formation, while in my invention the
analysis of the problem is pathologically made
of the device illustrated in Figs. 1 and 2.
Referring to the drawing, the numeral [0 des

formation of the element may be satisfactorily ac

mold, preferably under pressure to insure even

For supporting the element 10 in operative po
