What Are Posterior Teeth?

The posterior teeth are caused by the premature loss or retention of the deciduous molars, causing the upper and lower teeth of the permanent teeth to be displaced or the cheeks of the lower posterior teeth to be displaced, which can cause individual posterior teeth to reverse.

1. The dislocation of the upper and posterior teeth of the permanent teeth or the buccal displacement of the lower posterior teeth due to the premature loss or retention of the primary molars can cause individual posterior teeth to reverse.

2. Deep caries on one side, can only be chewed with the other side, the long time can cause the majority of unilateral posterior teeth reverse.

3. Abnormal pressure on one side of the lower jaw, such as the habit of supporting the cheeks on one side for a long time, can gradually lower the lower jaw to the other side, but also cause the majority of the other side of the posterior teeth.

4. In patients with mouth breathing, the pressure on both cheeks increases, and the upper dental arch gradually narrows, which can cause most posterior teeth on both sides.

5. In patients with cleft palate, the width of the maxillary arch of the upper teeth is underdeveloped and bilateral posterior teeth are often inverted.

It can be seen that unilateral posterior teeth or bilateral posterior teeth can also be combined with anterior teeth. It also affects bite function, maxillofacial development, and temporomandibular joint.

Not only cause disorder of occlusal relationship, but also cause facial

1. One maxillary unilateral pad appliance can be worn on one posterior tooth, that is, the normal one posterior tooth can be used to raise the occlusion to disengage the opposite side from the knot; Adjust the tongue spring to move the upper posterior teeth to the buccal side to correct the posterior posterior pads. After reversing the abrasion, it should be abraded in time. In the process of correction, the patient needs to adjust the sharpness of the upper posterior teeth and Lower buccal tip of the posterior teeth to make a good relationship. For individual posterior teeth, in addition to using a pad appliance, the maxillo-mandibular fixed appliance can also be used to pull the cheeks and tongues of the maxillary mandibular teeth in order to release the posterior teeth.

2. Bilateral posterior teeth, or unilateral posterior teeth, and the other posterior teeth are the opposite. The upper arch of such patients is obviously narrow, and the maxillary split base can be used. Use the split spring to expand the upper arch width. A band and a lip arch are made on the lower jaw, and the width of the lip arch is adjusted to reduce the width of the lower dental arch at each follow-up visit. After the normal relationship is established on the opposite side, the upper jaw can be changed to a side pad appliance, and a reed on the opposite side is used to continue to correct the upper and posterior teeth on this side to move to the buccal side to correct the reverse. After anti-relief, wear pads are divided. In the process of correction, it can be adjusted with the adjustment of the tooth tip to facilitate construction. This kind of correction has a good effect at the developmental age. After counter-correction, it can be combined with the training of chewing muscles and temporal muscles to consolidate the correction effect and establish balance. In addition, helical spring split base appliances can also be used.

Prevention should start from the fetal stage, and mothers should strengthen nutrition and enhance fetal constitution during pregnancy. Infant children are best breast-fed, so that the lower jaw does a proper extension of the lower jaw, and cooperate with the muscles of the tongue, lips, and cheeks to coordinate the development of the maxillofacial muscles. Childhood is a period of vigorous growth and development of children. Not only should we properly increase diet nutrition, but also properly increase the hardness of the food, so that each part of the child's structure can be fully stimulated and chewing function can be improved. In addition, it is important to keep your mouth clean.
