Abstract

The invention provides a lower jaw mandible expansion device matched with lip bumpers. The device comprises a mandible expansion component and a lip bumper component, wherein the mandible expansion component comprises a hyoid arch, two first molar bands, two first fixing blocks which are respectively fixed on outer sides of the first molar bands, two second fixing blocks which are respectively fixed on tongue sides of the first molar bands, and a tongue expansion arch wire which is arranged on the inner side of a U-shaped area of the hyoid arch; the tail ends on both sides of the hyoid arch are detachably connected with the second fixing blocks; one end of the tongue expansion arch wire is fixedly connected with the hyoid arch; the tongue expansion arch wire has expansion force far away from the tongue side; the lip bumper component comprises a labial arch and two lip bumpers; the tail ends of both sides of the labial arch are detachably connected with the two first fixing blocks, andthe two lip bumpers are detachably arranged on sections corresponding to positions of vestibular grooves of an anterior tooth area on the hyoid arch. The invention provides the lower jaw mandible expansion device matched with the lip bumpers can be used at mixed dentition and permanent dentition, deciduous and permanent tooth replacement at the mixed dentition is not affected, and bad habits suchas lower lip biting and the like can be avoided.

Description

technical field [0001] The invention relates to a mandibular arch expansion device matched with a lip stop, which belongs to the field of dental equipment. Background technique [0002] In the field of orthodontics, due to bad habits such as biting the lower lip, the mandibular anterior teeth are tilted, and the mandibular dentition is crowded, which is aggravated during the growth and development period. However, there are few devices currently on the market for mandibular expansion, especially those suitable for mandibular expansion in the deciduous and mixed dentition stages. Moreover, because children have bad habits such as biting their lower lip, traditional treatment instruments cannot effectively avoid these bad habits while expanding the arch. As a result, there is no good treatment plan for young patients with dental diseases. .
