What kind of retainer is better?

Many people's teeth are not neat enough, which has a serious impact on their image, so they feel very inferior and annoyed. Therefore, in order to improve many people's choice of orthodontic surgery, the method of retainer braces correction is very good. The types of retainers, including splint retainers and improved Hawley retainers, are very effective. I suggest you choose the method that suits you.

Splint-type retainer: The two parts of the plastic base on the lip side are connected by steel wires across the abduction gap between the canine and lateral incisor, and between the molar and premolar to form a splint, and the steel wires with diameters of 0.9mm and 0. 1mm are embedded in the plastic base 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.

Modified Hawley retainer: it consists of long labial arch and dental arch bent vertically on both sides of the base. The labial arch enters the basal part from the distal end of the last molar on both sides. Adjusting the vertical curvature of labial arch slightly can increase the retention force of retainer. This retainer does not pass through the steel wire in the abduction gap, so it allows the teeth to adjust slightly spontaneously after orthodontic treatment, thus forming a more ideal occlusal relationship during retention. It is often used for maintenance after extensive tooth movement.
