The clasp-wireframe appliance is realized in the form of mountable on the lower lateral segments of teeth support-retaining wireframes interconnected by vestibular and lingual arches as well as the arched clasp, which is parallel to the anterior section of the hard palate. The vestibular lingual arch or wireframe dispersed along the height of the upper frontal teeth is fixed on the clasp through orthodontic springs (see FIG1 Mailyan 8-1). The clasp-wireframe appliance for the treatment of mesial occlusion may be realized with the occlusal plates fixed on the support-retaining wireframes , see FIG2 Mailyan 8-1. Activation of the springs on the upper frontal teeth contributes to their mesial shift, while counterforces distally effect on lower jaw through the clasp.

Appliance with a maxillary labial plate.

The construction of this appliance differs from the above mentioned clasp-wireframe appliance in that on the vestibular surface of segments of support-retaining wireframes there are guide rings, in which the ends of the vestibular arch with elliptical springs and maxillary labial plates are mounted with an ability of fixing and removal, see FIG 3, Mailyan 8-2 The modification of the appliance, realized without palatal clasp wire and elements fixed on it, is applied at treatment of mesial occlusion in combination with maxillary wireframe appliances.In this case, the functional parts are applied at night and during the day an elastic traction is applied between appliances. The activation of elliptical springs of the vestibular arch with labial plates allows to influence distally upon the lower dentition by the force of masticatory and mimic muscles and promote an appositional growth of maxilla’s frontal section.
