Bruxism is considered a parafunctional activity of the stomatognathic system in which there is an excessive activity of the masticatory muscles present. Associated symptoms of bruxism are clenching of the jaw and teeth grinding, which may result in tooth damage and wear, as well as temporomandibular disorders and the damaging of the periodontal ligament. Causes of this condition have not yet been uncovered with certainty, although the widely accepted view is that emotional factors and stress play a role. Diagnostics rely mostly on a precise anamnesis, a general health examination, as well as diagnostic methods carried out at a laboratory, such as polysomnography. Bruxism is incurable, however, therapy can be prescribed to better manage the symptoms and rebuild lost tissue. The symptoms most commonly include painful teeth and masticatory muscles, migraines, as well as a gradual decrease of the vertical dimension of occlusion. Strategies for making symptoms manageable are a reduction in psychological stress, physical therapy, or medication. A splint designed to function as a stabilizer has proved to be an efficient way of maintaining a harmonious link between the jaw and the structures in the temporomandibular joint. Other than the reduction of direct symptoms, an important part of therapy are also the reconstructive procedures of rebuilding the lost dental tissue, such as providing fillings and various prosthetics. Crowns have proven to be a good tool for rehabilitation, as well as increasing the vertical dimension of occlusion. Since patients suffering from bruxism develop strong pathological impulses pertaining to their masticatory muscles, it is important to ascertain if there is a way to apply the fixed-prosthetic treatment, as well as to conduct the pre-prosthetic preparation for the patient. It is crucial to choose the right material to be used during reconstruction and then provide them with a splint that can lessen the impact of the condition.
