Lockjaw has a great impact on chewing function, maxillofacial development and the health of chewing organs, and should be corrected as soon as possible. The principle of correction is to raise the bite and release the locked jaw relationship for correction. 1. Buccal misalignment of the upper posterior teeth is common in individual cases of locked jaw. Orthodontic treatment can use a unilateral jaw pad removable appliance, that is, a unilateral jaw pad is installed on the upper or lower dental arch on the healthy side to release the locking teeth from the cusp locking, and a ring is made on the upper and lower locking teeth. Weld a traction hook on the buccal surface of the maxillary dental band and the lingual surface of the mandibular dental band, hang a rubber band between the upper and lower jaw traction hooks, and anchor the upper and lower teeth alternately for correction. After the lock-jaw relationship is resolved, the jaw pads are reduced or removed in stages, and the cusps of the lock-jaw teeth that have not experienced physiological wear are simultaneously adjusted to allow the entire mouth to be rebuilt. Desensitization treatment can be used when adjusting the cusps of teeth.
2. Positive lockjaw between the upper and lower second molars on one side is clinically more common, and the degree of buccal misalignment of the upper molars is often greater than the degree of lingual misalignment of the lower molars. If the third molar on the same side has not yet erupted but is about to erupt, the second molar on that side can be extracted so that the third molar can adjust itself to the position of the extracted second molar and erupt, establishing a normal jaw relationship with the lower second molar.
3. Positive lockjaw with most of the back teeth on one side is common when the lower dental arch is narrow and the cheek is narrow. On the lockjaw side, the lower back teeth are severely misaligned lingually, but the buccal misalignment of the upper back teeth is not obvious. This kind of pad makes the lockjaw teeth break away from the cusp lock. The appliance places a double-curved tongue spring on the lingual side of the lower back teeth on the lockjaw side to correct the buccal movement of the lower back teeth on the lockjaw side to correct lockjaw. Since the jaw pad is used on the healthy side, the tension of the buccinator muscles is increased, which helps the upper posterior teeth on the lockjaw side move lingually, which is beneficial to the correction of lockjaw. After the locked jaw relationship is released, the jaw pads are adjusted in stages, and the excessively high cusps of the locked jaw teeth are also adjusted and desensitized if necessary.
When correcting individual posterior lockjaw or multiple posterior lockjaw, attention must be paid to gap problems. If there is insufficient clearance. The gap needs to be opened up first; if the side is seriously crowded, it needs to be subtracted.
Lockjaw can be corrected through orthodontics. Patients can choose traditional orthodontics or invisible correction according to their own dental condition and financial situation.
1. Traditional orthodontic brackets are used to correct deep overbites of teeth through the function of braces.
2. Use invisible braces. It is generally expected that the duration of orthodontic treatment will be about 1 year. However, the actual time required varies from person to person and needs to be analyzed on a case-by-case basis. Since the degree of dental deformity varies from person to person, the time required for treatment will naturally vary. However, if you work well with your orthodontist, pay attention to maintaining personal oral hygiene, protect your appliances from damage, and go back for follow-up appointments on time, the time for orthodontic treatment will be greatly shortened.
