Abstract

The objective of this study was to compare the record of number of contact points and mounting time between Michigan occlusal splints (MOS) made with and without face bows in patients diagnosed with bruxism. A total of 90 splints were made and distributed among 45 patients diagnosed with bruxism at the Oral Rehabilitation Clinic of Benemerita Universidad Autonoma de Puebla. The two splints (one made with a face bow mounted model and the other one without it) were compared at the articulator and clinically. The comparisons were made with Wilcoxon statistical test and a significance level lower than 0.05. The splints with face bows showed a greater average of contact points in the mouth (11.67) compared with the ones without face bows (11.58), with no significant difference (p = 0.799). There are no significant differences in using face bows for developing MOS in bruxism patients.
