ORTHOPEDIC DEVICE Russian patent published in 2001 - IPC

FIELD: medical engineering. SUBSTANCE: device has four orthodontic rings. Two rings are set on the first permanent molars and two of them on the first premolars. Nonremovable caps of the apparatus has two arcs. The upper arc repeats the shape of the upper denture and is placed between palatine surfaces of the upper first permanent molars and palatine transverse folds. The upper arc is soldered to the outer surface outside from the palatine surface of the orthodontic rings to the upper first permanent molars and the first premolars. The lower arc repeats the shape of the lower denture and comes down along oblique line from the palatine surfaces of the upper first permanent molars to the alveolar process in the vicinity of the lower incisors from the side of tongue. The lower arc is soldered to the outer surface outside from the palatine surface of the orthodontic rings to the upper first permanent molars. The arcs are joined by means of vertical rods which number is selected in individual way depending on denture arc size. The frontal member envelopes palatine surfaces of the upper incisors and, when needed, also that of canine teeth. The frontal member has C-shaped rounded surfaces at the ends open in medial direction. Frontal processes of expansive screw are soldered to the rounded surfaces to accelerate opening of palatine suture. Screw body is set on the median palatine line at the level of the upper first premolars. The posterior processes are turned towards the outer surface outside from the palatine surface of the orthodontic rings on the upper first permanent molars. EFFECT: wide range of palatine functions of the device; improved esthetic properties. 1 dwg
