Orthodontic device

Abstract

Mobile orthodontic device of a functional type comprises a pair of posterior lateral bites ( 2 ) in the form of metal plates connected together by means of a metal wire ( 4 ). The posterior bites ( 2 ) are designed to be set freely floating between the upper dental arch and the lower dental arch. The device also comprise a pair of vestibular shields ( 3 ), made, for example, of synthetic material, associated, respectively, to the two posterior lateral bites ( 2 ). The device is without palatal plate, so that the metal wire ( 4 ) constitutes the only connection between the posterior lateral bites ( 2 ). The device can comprise an anterior bite ( 6 ) in the form of a metal plate connected to the two vestibular shields ( 3 ) through a second metal wire ( 5 ). There may moreover be present one or more lateral expansion springs ( 7 ), designed to act on the molars, and one or more anterior expansion springs ( 8 ), which act on the incisors.

1 . Orthodontic device of a functional or functionalizing type, comprising:
 at least one pair of posterior lateral bites in the form of a metal plates provided with means for mutual connection, designed to be set freely floating between the upper dental arch and the lower dental arch; and   a pair of vestibular shields, made, for example, of synthetic material, each associated to each of the two posterior lateral bites,   said means for connection of the posterior lateral bites being constituted by at least one metal wire, which connects together either the two vestibular shields or directly the two posterior lateral bites,   said device being characterized in that it is without palatal plate so that said at least one metal wire constitutes the only connection between said posterior lateral bites.   
     
     
         2 . The orthodontic device according to  claim 1 , characterized in that it comprises an anterior bite in the form of a metal plate, designed to be set freely floating between the upper dental arch and the lower dental arch in a position corresponding to the incisors. 
     
     
         3 . The orthodontic device according to  claim 2 , characterized in that the anterior bite is fixed to a second metal wire that connects together either the two vestibular shields or the two posterior lateral bites. 
     
     
         4 . The orthodontic device according to  claim 2 , characterized in that said anterior bite is a single bite in the form of a metal plate. 
     
     
         5 . The orthodontic device according to  claim 2 , characterized in that said anterior bite is a double bite comprising two metal plates set above one another and at a distance apart, joined together in a bent-back central portion so as to bestow elastic properties on the anterior bite. 
     
     
         6 . The orthodontic device according to  claim 1 , characterized in that it comprises one or more lateral expansion springs, which are designed to act on the molars and are connected directly to the vestibular shields. 
     
     
         7 . Orthodontic device according to  claim 6 , characterized in that it comprises one or more anterior expansion springs, which are designed to act on the incisors and are carried by the aforesaid lateral expansion springs. 
     
     
         8 . The orthodontic device according to  claim 1 , characterized in that said vestibular shields are asymmetrical.
