Dental bite disorder is generally a dental bite disorder refers to the bite between the teeth and the teeth when it is not normal, and is not a corresponding bite of the cusp interlocking position, so this bite disorder is likely to have periodontal pathology, jaw trauma, and temporomandibular joint pathology. In severe cases, mouth opening may be limited or difficult, causing a range of problems such as chewing and eating. Dental bite disorders generally involve the following factors: 1. teeth: misalignment of teeth or missing defects can cause changes in bite habits, resulting in disorders; 2. jaws: incongruity between the maxilla and mandible may cause dental bite disorders; 3. temporomandibular joints: disorders and incongruity of the occlusal muscles can also cause misalignment of the dental bite relationship.
