What is lockjaw? How can lockjaw be corrected? Answer

Locked jaw has a great impact on masticatory function, maxillofacial development and the health of masticatory organs, and should be corrected as early as possible. The principle of orthodontic treatment is to elevate the occlusion and lift the lockjaw relationship in order to correct it. Individual teeth lock jaw is mostly seen in the upper back teeth buccal misalignment. Orthodontic treatment can be used unilateral jaw cushion movable orthodontic appliance, that is, in the healthy side of the upper arch or lower arch device unilateral jaw cushion, so that the locking jaw teeth from the cusp locking junction, in the upper and lower locking jaw teeth, each do a band ring, in the buccal surface of the maxillary teeth with a ring and mandibular teeth with a band ring of the lingual surface of the welded traction hooks, hanging rubber bands in the upper and lower jaw between the hooks, the upper and lower teeth interacting with the support of the orthodontic treatment. After the locking relationship is lifted, the jaw cushions are reduced or removed in stages, and the cusps of the locking teeth that have not been physiologically abraded are ground at the same time, so that the whole mouth can be rebuilt. Desensitization can be used in conjunction with cusp resharpening.

2, a side of the upper and lower second molar is locked jaw clinically more common, and the upper molar buccal misalignment, often than the lower molar lingual misalignment of the degree of serious. If the third molar on the same side has not yet erupted and is about to erupt, the second molar on that side can be extracted so that the third molar can erupt on its own in the position of the second molar that has been extracted, and the lower second molar can establish a normal jaw relationship.

3, most of the posterior teeth on one side of the orthognathic lockjaw is common in the lower arch buccal narrow, lockjaw side of the lower posterior teeth to the lingual side of the serious misalignment, but the upper posterior teeth buccal side of the misalignment is not obvious. This affected cushion, so that the locking jaw teeth out of the apical locking junction, orthodontic appliances in the locking jaw side of the lower posterior teeth lingual side of the placement of double curved tongue spring, orthodontic locking jaw side of the lower posterior teeth to the buccal side of the movement to correct ortholigamentous locking jaw. Due to the use of jaw pads on the healthy side, the tension of the buccal muscles was increased, which helped the upper posterior teeth on the clavicle side to move buccolingually, while favoring the correction of the clavicle. After the lockjaw relationship is lifted, the jaw pads are adjusted and ground in stages, and the excessive cusps of the lockjaw teeth are also adjusted and ground, together with desensitization measures if necessary.

Correction of individual posterior teeth lock jaw or most of the posterior teeth lock jaw, pay attention to the gap problem. If the gap is insufficient. Need to open up the gap first; such as severe crowding side need to cooperate with the number of reduction.

Locked jaws can be corrected through orthodontics, patients can choose traditional orthodontics or invisible orthodontics according to their own dental condition and financial situation.

1, the use of traditional orthodontic brackets, is through the role of braces to achieve the correction of teeth deep overlay.

2, using invisible braces. It is generally expected that the course of orthodontic treatment is about 1 year. However, the actual time required varies from person to person, and specific problems have to be analyzed. Since the degree of malocclusion varies from person to person, the time taken for treatment is naturally different. However, good cooperation with the orthodontist, pay attention to maintain personal oral hygiene and health, protect the aligners from damage, and go to the follow-up appointment on time, in this case, the orthodontic treatment time will be greatly reduced.
