ABSTRACT
Objective: The purpose of this study was to evaluate the displacement of the condyle and dental arches with the record of an immediate deprogramming splint one month after the use of the splint in TMJ symptomatic patients.
Material and methods: The records of 15 symptomatic patients who were subjected to a questionnaire and clinical evaluation for their inclusion in the study were used. Casts were mounted from three records: 1) maximum intercuspation, 2) centric relation with Roth power centric bite, and 3) centric relation a month after the daily use of the splint. Condylar position of the right and left side in horizontal and vertical was measured and compared as well as the vertical and horizontal overbite in each of the three records.
Results: There were no significant differences in the results obtained from the records made in centric relation with an immediate splint and in centric relation after the use of the occlusal splint. However, it was found that there is a considerable discrepancy in the condylar and dental displacement in a position of maximum intercuspation and in centric relation after the use of the splint, as well as an improvement in the patients’ symptoms with the use of that device.
Conclusions: Cast mounting on the articulator is recommended for diagnostic purposes, in the measurement of condylar position and the use of splint in patients with TMJ pain to identify more reliably the goals to consider during and by means of orthodontic treatment. Otherwise they could be masked and determine a different course in treatment planning.
