and the like the wire 106 which is extended along near cervical area of lingual surface is brazed between the c clasps 103 as shown in fig3 and 4 the resin plate 102 is provided along a side edge of a palate and has unevenness fitting with inside surfaces of teeth the reinforcing wire 104 is extended from the c clasps 103 along the inside surface of the teeth and the bridge wire 105 traversing a rear edge of the palate is suspended and brazed between the c clasps 103 note that in this embodiment the second molars 126 or first molars may be surrounded by the c clasps 103 according to such a retainer 10 l in addition to the effects of the retainer 100 the retaining force can be increased by the labial wire 106 a retainer 111 shown in fig5 has a form in which adams clasps 109 are used around the first molars 125 in this way adams clasps may be used instead of the c clasps 103 in a retainer 121 shown in fig6 the first molars 125 and the second molars 126 or first molars are surrounded by bifurcated c clasps 107 this makes it possible to induce articulation of teeth and tusks in an eruptive phase a retainer 131 shown in fig7 has a form in which resin 108 is added to the labial wire 106 in the anterior teeth as shown in fig8 in the retainer 101 shown in fig2 the retainer 131 makes over treatment for the respective teeth and tusks possible.
