splint for treatment of fractures of the lower jaw and conductor for making thereof

摘要

A splint for treatment of fractures of the lower jaw comprises an arc basis made of annealed orthodontic wire and loops, which are formed in it as gearings for rubber rodss by consecutive bending of wire on 90 ° and 180 ° in a face-to-face plane. One of loops is placed directly above a line of jaw fractures, made in the form of an elastic W-shaped element.A conductor for manufacturing the splint comprises a platform and cores 1.6 mm rigidly connected with it. They are installed on the top, middle and bottom parallels along the platform. A bypass core 4 mm is located in a point of crossing of a cross-section axis of the platform with the top parallel. The bypass cores of the top parallel are placed with an interval of 11 mm, middle one - in pairs, with a gap of 4 mm and 7 mm, and bottom one- in pairs, with a gap of 3.5 mm and 7.5 mm, under the bypass core 4 mm on the bottom parallel - with a gap of 7.5 mm. The gap axes are combined with cross-section axes of bypass cores of the top parallel, and the distance between all parallels makes 2.5 mm.
