Distraction device for use in bone mandibular distraction osteogenesis and a method for constructing the device.

摘要

Distraction osteogenesis device for use in mandibular distraction osteogenesis, and a method for constructing the device. The device (1) includes several crowns hitch for placement jaw teeth of the patient, specifically four latches (2) intended to act on bicuspid crowns and four (3) intended to act on the molar crowns, welded screws universal expansion (4) to the outer side of said crowns, and a sliding tube (5) inside or lingual side, so that when the screws (4) expand the metallic belts bicuspids (2) are separated from the tapes metal molar (3). In this sense each expansion screw (4) has two sectors (6) and (7) separable by a screw mechanism (8), its power separation guides (9) for correct relative mobility being. Figures 2 and 3.
