Diastema closing device

Abstract

The invention discloses a diastema closing device, which comprises an installation tube seat, a correction elastic element and a regulation and rotation force increasing cone, wherein the installation tube seat, the correction elastic element and the regulation and rotation force increasing cone are fixedly installed on an agomphosis position implantation body; the correction elastic element comprises a middle connecting tube of a hollow tube body structure and two correction folding wings which are symmetrically arranged; the correction folding wings are cooperated and are fixedly symmetrically arranged on the outer side wall of the middle connecting tube; and the outer side wing of each correction folding wing is independently adaptively coated and abutted against the axial angles of the cheek side and the tongue side of a corrected tooth. By use of the diastema closing device, diastema closing processing of an upper jaw tooth or a lower jaw tooth can be realized, meanwhile, the correction folding wings of the correction elastic element are coated and abutted against the teeth on two sides of the agomphosis position, so that the corrected tooth does not rotate or deflect in a correction process, in addition, the regulation and rotation force increasing cone is used for slowly applying force, the correction folding wings slowly close the diastema in a progressive way, force application more conforms to the physiology, and inclination and rotation of the tooth can be simultaneously corrected.

Description

technical field [0001] The invention relates to the field of design and production of special orthodontic appliances and supplies for dentistry, more specifically, an interdental space closer. Background technique [0002] After the dentition is lost, the teeth on both sides of the edentulous area are displaced, and there are gaps between the teeth; there are often gaps between the teeth of the natural dentition. The traditional method is to close the gap through orthodontic treatment, directly bond the brackets on the teeth, arrange the teeth through the arch wire, and close the gap between the teeth. Carry out orthodontic treatment to tooth by above-mentioned method, not only correction time is long, and cost is high, and attractive in appearance is lacking, and oral hygiene is difficult. Invisible orthodontics also has the above-mentioned problems. If the interdental spaces are not closed, food impaction will appear in the teeth after implant restoration, leading to peri...

Problems solved by technology

[0005] 1. The limitation of this method is quite obvious. It can only close the gap between the maxillary teeth and cannot close the gap between the mandibular teeth, because the mandible cannot be implanted with anchorage. Mandibular tooth single surface (i.e. the outer surface) is used for traction and pull correction, and when the operation is performed on one side and one side, it is easy to cause the outer surface of the tooth surface to tilt due to spring pulling, resulting in failure to close the interdental space

[0006] 2. This method not only has the disadvantages of high surgical risk, high su...
