Nanoce arch orthodontic molar control device

Abstract

The invention discloses a Nance arch orthodontic molar control device. The device comprises a base support part, a pair of sliding block assemblies, a belt ring, and a retention part;sliding rods are arranged on the two sides of the base support part respectively; when the base support part is arranged on the front portion of the hard palate of a patient, the sliding rods are located on the palate sides of dentitions on the two sides of the upper jaw of the patient respectively; each sliding block assembly is arranged on one sliding rod, each sliding block assembly comprises an elastic piece and a pair of sliding blocks, the two sliding blocks are sequentially arranged on the sliding rod in a sliding mode, and the elastic piece is connected between the two sliding blocks; the belt ring is arranged on the sliding block close to a distal direction, and the belt ring is installed on the molar of the patient; and the two ends of the retention part are connected to the two sides of the base support part respectively, and a retention ring is arranged on the retention part. According to the Nanoce arch orthodontic molar control device, the positions of maxillary molars can be controlled more simply and conveniently, and various orthodontic anchorage designs are realized.

Description

Technical field [0001] The present invention belongs to the field of orthodontics, and more particularly to a Nance bow is a distortion apparatus. Background technique [0002] In orthodontic treatment, the extraction correction is a conventional treatment design. During the process of correction, the distance between the pull-out teeth is reasonably assigned to control the distance from the back tooth, and is essential for achieving the ideal correction target. Applying more extensive traditional molar control devices include NANCE Bows (South Sichu Bows), head cap-J hooks, front traction, mandibular traction, etc., have security, non-invasive advantages, but still existed insufficient control capability, depending on patients, The shortcomings such as the front teeth are easy. In recent years, the bile control of bile control is more common in the field of oral orthodontics. Although the planting microscopy control has a high comfort of the patient, it can absolute control of t...
