Indications for the use of occlusal splints for muscle relaxation
The occlusal splints or guards for muscle relaxation are devices that are placed between the maxilla and mandibular with the aim of relaxing the masticatory muscles and obliging occlusion to occur in a certain position. There are many designs of occlusal splints but they are generally made of acrylic, are rigid, separate the maxilla and mandibular by approximately two millimeters, and permit stable bilateral occlusion and canine disocclusion. In the treatment of fibromyalgia, certain authors tend towards the use of resistant thermoformed plates of 0.6 to 0.8 mm. Occlusal splints are usually also indicated in patients who have undergone major rehabilitation in order to prevent bruxism (7)(44).
