Abstract

The invention discloses a device for periodontal ligament distraction and osteogenesis to mesially move molars, which comprises a first belt ring set on molars or premolars mesial to the edentulous area and a second belt set on molars to be mesially moved The ring, the first belt loop and the second belt loop are connected by a helical distractor, and the helical distractor is arranged on the buccal side of the teeth, and the helical distractor includes a first buccal slider, a helical rod , a nut, a second buccal slider and a buccal slider; it also includes a first lingual slider and a second lingual slider arranged on the lingual side; the first lingual slider and the second lingual slider The side sliders are connected by a lingual side slider bar and an elastic device. The invention solves the problem in the prior art that the molars are deflected and tilted when the molars are moved mesially over a long distance.

Description

technical field [0001] The invention relates to the technical field of oral medicine, in particular to a device and a treatment method for periodontal ligament distraction osteogenesis for mesially moving molars. Background technique [0002] Clinically, patients who lose their mandibular first or second molars due to caries and trauma are common, such as figure 1 Shown is a schematic diagram of the missing mandibular first or second molars. At present, the main solutions include implant restoration and crown bridge restoration. If the patient still has the third molars, the molars can also be moved mesially through orthodontics to replace the third molars. Second molars, the second molars replace the first molars. The cost of implant treatment is high, and patients bear the risk of unnecessary implant surgery; the restoration of crown and bridge needs to grind away healthy tooth tissue, and the chewing function is not as good as that of normal teeth. However, most patient...
