<p>The invention relates to an apparatus for the treatment of overbite, said apparatus comprising a first band (12) on the front premolars in the lower jaw and a second band (13) on the front molars in the upper jaw, said bands (12, 13) being connected by a rod (14) consisting of an insertion part (15) which may telescopically slide into a receiving part (16). In order to assemble or disassemble the apparatus the end of the insertion part (15) facing the first band (12) is inserted pivotably into the side face of a first bushing (25) and the receiving part (16) is provided with a tube (19) designed to receive a rod (17) on the insertion part, said tube (19) having an arm (20, 22) which is inserted pivotably into the side face of a second bushing (25, 25a, 25b), and at least one of the two bushings (25, 25a, 25b) is via a pin (34) secured to its band (12, 13) by a laterally of the bushing (25) insertable or removable, respectively, locking ring or a similar device (33). There is thus achieved a safe and secure connection between the telescopic rods (14) and the bands (12, 13) without any use of screws which might loosen during the use and then be swallowed by the user. There is also described a method for assembling respectively disassembling the apparatus.</p> |
