Masticatory disorders |
The crunch when opening or even when closing the mouth is the most common sign encountered during a disorder of the masticatory joint. This produces when there is a disturbance between the articular disc and the condyle (head of the mandible). In the vast majority of cases, crackling is rarely painful. However, pain may arise in a patient with very severe joint dysfunction. The pain and stiffness of the muscles around the jaw can often be the result of parafunction, that is, tightness of the teeth and bruxism. These are often caused by psychological stress. Clenching of teeth and bruxism are the result of the unnecessary and exaggerated contraction of chewing muscles. This in the long run causes muscle fatigue accompanied by pain and stiffness. Premature wear of teeth is often a sign of parafunction and the use of an occlusal plate can prevent this. |

TreatmentsSeveral treatments are possible for the problems of the jaw. The sequence varies according to the individual and the diagnosis. The treatment plan usually includes a multidisciplinary approach with some care provided by a team of professionals and others by the patient himself at home. Initially, we try to eliminate muscle spasms and joint pain. Medication or infiltration can be used. Home care is also important at this stage. Stress management, physiotherapy or osteopathy techniques may be indicated. Making a clear plastic appliance (occlusal plate) that fits your teeth helps to relax the jaw muscles and reduce pain. This device can also be worn at night to prevent premature wear of the teeth. The correction of occlusion by equilibration, orthodontics or surgery may be considered in some cases of severe malocclusion or when conservative treatment does not give the expected results. |
