The condition property can be divided into two groups, occlusion of the original dental and skeletal classification *. As a result of the differences in wealth occlusion skeletal shape, size or position of one or more teeth in the jaw can be created. For example, if one of the jaw are very large or very small or very large, and one of them is very small, these conditions can be regarded as the property of skeletal occlusion. For these patients, help coordinate simple dental arch does not make that much, because the teeth at appropriate positions due to lack of correct placement of the jaw are not supposed to be on each other. The apparent condition of the property, often skeletal occlusion in inappropriate for the patient is mobile. In this case, if the mandible is very small, if the person is too convex or کوژ, but if the lower jaw is too large or too small upper jaw, or both of these conditions exist, along with the other person too concave or KAV would be. Another of the ناهنجازی jaw ودندانی problem is avarjt; avarjt as being ahead of the maxilla is also known, in practice makes the mandibular teeth back in the mouth than the maxillary teeth are. In this case the use of orthodontic treatment alone cannot be sufficient to correct skeletal problems, and also owned by the occlusion can not be apparent if the patient's problems in addition to the placement of teeth problems on each other on the track side. The surgery a patient's jaw, jaw, or both, usually to correct a situation of the jaw, teeth biting performance improvements, increasing the apparent form of beauty, and reduce the problems related to the respiratory system can be used.

In the event that the status of the placement of the jaw on each other in a patient is fit, occlusion of teeth property can result in improper growth excessive accumulation of teeth or they are created.. In these circumstances, the use of specific methods of orthodontic treatment alone can use the brace are stable teeth placement status on each other to modify.
