RESUMO

The aim of this study was to evaluate the effect of balanced splints with bilateral balanced guidance, canine guidance and nonoccluding splints. For that purpose, a study sample was employed comprising 57 individuals presenting with signs and symptoms of disc displacement with reduction and complaint of TMJ pain and tenderness to palpation of the TMJ at least at one side, who were randomly assigned to three groups: 1st group: 19 individuals submitted to therapy with a modified splint, the design of which allowed simultaneous contact of part of the teeth on all parts of the splint during excursive movements. 2nd group: 20 individuals submitted to therapy with a splint with canine guidance, which established disocclusion of all other teeth during excursive movements. 3rd group (control group): 18 individuals who received a nonoccluding splint that did not interfere with the occlusion. The entire sample was followed for 6 months and submitted to evaluation by means of the visual analogue scale (VAS), palpation of the TMJ and jaw elevator muscles and analysis of the mandibular movements and joint sounds. An evaluation concerning the patient’s report regarding the joint sounds, occlusal changes and comfort was also performed. The results demonstrated that the type of guidance did not influence the behavior as to pain reduction, yet both occlusion splints were better than the nonoccluding splint as to the pain scale. Besides, despite of the achievement of similar outcomes in relation to opening, left lateral movement, protrusive movement, TMJ pain to palpation and also pain to palpation of most muscles analyzed, there were statistically better outcomes for the splints with balanced guidance (group I) and the splints with canine guidance. Concerning the subject’s reports for comfort with the splint and joint sound, there was a better association for groups I and II. On this basis, it was concluded that there is no difference between the balanced guidance and the canine guidance for the treatment of individuals with disc displacement with reduction.
