The increase of pain symptoms in the temporomandibular joint (TMJ) challenges the scientists to find a more effective therapy. The popular treatment of the temporomandibular disorder (TMD) are eg occlusal splints, orthodontic treatment, electromyographic biofeedback, medication, etc. Among these splint therapy is more successful than the others especially in dealing with pain in the TMJ. Orthodontics as a treatment for the TMD quite often creates new complains on TMJ during and/or after treatment. The extrusion of the posterior teeth in reducing anterior deep overbite have been proposed as possible cause of TMD. This paper reported that a relaxation splint was an effective solution to relieve the pain in the TMJ for the orthodontic patients where occlusal factors were related. One mounth after the splint therapy, the pain in the TMJ was slowly dissapeared, and the orthodontic treatment can be continued with the splint as an occlusal height guidance.

Occlusal splint is commonly used for treatment of the temporomandibular joint disorder (TMD). It can be made of hard and soft material. Hard occlusal splint (HOS) which was known earlier had been recognized more effective then soft occlusal splint (SOS) which recently gained some popularity. This clinical study based on case series was to detemined which type of occlusal splint was more effective for TMD. This study involved 20 subjects and they were divided into HOS and SOS group with 10 subjects in each group. HOS was processed with heat curing acrylic and SOS with vacuum former. Before and after 4 weeks of treatment, 5 TMD symptoms (impaired range of movement, impaired TMJ function, muscle pain, TMJ pain and pain on movement of mandible) were measured using Helkimo diagnostic index. The results were analyzed with Kolmogorov-Smimov Z's test. The findings showed statistically significant improvement in impaired range of movement and muscle pain in favor of HOS group (p<0.05). Although they were not statistically significant, HOS group showed better improvement than SOS group in TMJ pain and pain on movement of the mandible. In TMJ's function, no changes were found in both groups. In general, HOS was more effective than SOS for treating TMD in relatively short period of time. Despite of the phenomena, the popularity of SOS was not followed with its effectiveness.

Splint or orthopedic appliance is routinely used in the treatment of temporomandibular disorders (TMD). This appliance is used to alter occlusal relationship and to redistribute occlisal forces, to prevent wear and mobility of the teeth, to reduce bruxim and parafunction, to treat masticatory muscle pain and dysfunction, and to alter structural relationship of the TMJ. There are 2 kinds of splint, the permissive and non permissive. Stabilization splint and bite plane are permissive splints, and anterior repositioning appliance is a non permissive splints. Each kind of splint has its own indication. There is strong evidence that splint therapy is succesful in the treatment of TMD but there is no consensus of opinion on how splints work.
