? Orthodontics is the main method to restore the neatness and beauty of teeth, but some people will rebound after orthodontics. Why? What will happen? Below, experts made a detailed introduction on this issue. 1. Overcorrection of teeth, such as deep overbite or opening and closing, should be corrected to over-correction of normal overbite. The same treatment should be done for twisted teeth, and excessive treatment can often prevent rebound after treatment. 2, early treatment, through the correction of the jaw growth and development period, you can get a relatively stable effect. For cases such as tooth distortion, early treatment is recommended. 3. Sometimes, if the severely twisted teeth can't achieve natural retention only by mechanical retention after treatment, it is necessary to cut off the fibers around the tooth neck to obtain stable results, which can reduce the retention time. 4. Permanent reservation. In some cases, long-term wearing of retainer can not prevent recurrence, such as abnormal nail-shaped lateral incisors, upper central incisors, severely twisted teeth and missing permanent teeth. Fixed restorations such as crowns and bridges or removable partial dentures are usually used as permanent retention in clinic. 5. Orthognathic surgery. Simple mechanical correction is difficult to improve malocclusion, and often requires surgical treatment, such as mandibular protrusion deformity, opening and closing deformity and so on. The above is the introduction of experts. Orthodontics is a good way to restore the neatness and beauty of teeth at present, but in order to ensure its effect, advanced technology and professional doctor team can ensure its effect and safety, and the rebound will be less.
