Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontic instruments, in particular to a lingual fixed retainer. Background Art

[0002] After orthodontic treatment is completed, in order to maintain the corrected dental arch shape, retainers are needed to maintain the new position of the teeth on the alveolar bone. When the malocclusion does not recur, the retainer does not actively generate corrective force. When the malocclusion tends to recur, the retainer resists this tendency of tooth movement through a certain rigidity or elasticity.

[0003] However, the common adhesive lingual retainers on the market are mainly stainless steel twisted wire and stainless steel chain. Stainless steel twisted wire is a twisted structure formed by winding or weaving more than three strands of fine wires, with a circular or oval cross-section. Stainless steel chain is a soft metal chain obtained by crossing and flattening several stainless steel rings. The main disadvantage of stainless steel twisted wire and stainless steel chain retainer wire is that their multi-component structure makes each single component too small and has limited strength. Therefore, it is necessary to provide a lingual fixed retainer to solve the problem. Utility Model Content
