How to wear a metal retainer?

Retention is a measure to consolidate the curative effect of orthodontic treatment and keep the teeth in an ideal aesthetic and functional position, which is called retention. At this time, it is called a retainer. After orthodontics, after the appliance is taken out, because the teeth are still unstable in the new position, it is often necessary to wear retainers to keep the new position of the teeth on the alveolar bone and wait for the reconstruction of the alveolar bone.

The two plastic bases on the lip side of the splint-type retainer are connected by steel wires, which span the two abduction gaps between canine and lateral incisor and between molar and premolar to form a splint, and steel wires with diameters of 0.9mm and 0. 1mm are embedded in the plastic bases to increase the strength. The lingual upper edge of the splint stops above the lingual protrusion of the anterior teeth, and the other parts stop above the contour high point of the crown. The lower edge should cover the attached gum and reach as far as the buccal and lingual groove of the first molar. The thickness of the splint is1.5-2.0mm. Be careful not to put the crossed steel wire on the tooth extraction site to avoid the closed tooth extraction space from spreading again. This retainer can be used to keep the width and length of dental arch and the movement of complex teeth, and is suitable for adults with periodontal disease or loose teeth after treatment. It can be used as limited retention or permanent retention, mainly for mandible.
