Stent depressing second molar by using implant anchorage

Abstract

The invention relates to a stent depressing a second molar by using an implant anchorage. The invention belongs to the technical field of medical instruments in the orthodontic aspect. The stent provided by the invention comprises a first molar band ring (1) and traction hooks (3). The stent is characterized in that a pair of horizontal rods (2) parallel to gingival margin is provided on a distal direction of the first molar band ring (1) corresponding to cheek and tongue sides of an adjacent second molar; a pair of traction hooks (3) is respectively provided on each of the horizontal rods (2) at proximal and distal shaft angle positions of the second molar; a palatal connection body (4) close to an adjacent second premolar is provided on the first molar band ring (1) on the palatal side in the proximal direction; a buccal connection body (5) close to the adjacent second premolar and a positioning frame (6) are provided as a buccal side of the first molar band ring (1), wherein the positioning frame (6) matches an implant anchorage pin implanted on an apical alveolar bone on the buccal side between the first molar and the second premolar.

Description

technical field [0001] The invention relates to a bracket for depressing second molars by using implant anchorages, in particular to a bracket for depressing maxillary second molars by using implant anchorages for orthodontics, and belongs to the technical field of medical devices in orthodontics. Background technique [0002] In clinical oral cavity, it is common to cause excessive elongation of the opposing teeth due to the long-term loss of molars on one side, which affects the restoration of dentures. Traditional solutions include pulpotomy, surgical improvement, and orthodontic depression. The truncated crown will injure the pulp of the opposing teeth, and the surgical operation is traumatic and expensive. Therefore, these two methods are unfavorable for promotion. Implant anchorage has been widely used in the depression of molars, especially the reports on the depression of the maxillary first molars are more, and the reports on the depression of the second molars ar...

AI Technical Summary

Problems solved by technology

[0003] The number of implant anchorages implanted in lower molars by using implant anchorage is generally 2-4, but there are the following difficulties in implanting anchorage nails in the distal part of the second molar: a. The distal buccal operation space is limited, and Difficult to perform the operation smoothly; b. On the far side of the palate, there is a large palatine foramen, which contains rich nerves and blood vessels, and the operation risk is relatively high

However, simply implanting anchorage screws in the mesial area will cause the teeth to tilt in the mesial area.
