SUMMARY:

Objective: To evaluate the influence of different types of interocclusal registrations and assembly techniques in a virtual articulator on the clinical and laboratory preparation time of stabilizing occlusal splints made by digital workflow (CAD/CAM). Methodology: This is a randomized, double-blind controlled clinical trial, where the sample consisted of 30 patients diagnosed with sleep bruxism, who were randomly randomized into two groups according to the technique of mounting the model on the articulator virtual: GP (flat horizontal group) and GM (camper's table group). Three different types of interocclusal records were also evaluated for making printed occlusal plates, namely: “maximum habitual intercuspation” (MIH), “anterior recording device” (DAR) and “occlusal reeds”; and the techniques for designing the occlusal splints, these steps being subdivided into smoothing and delimitation, mounting the model of the upper model on the articulator (varying in the horizontal plane and camper's table), designing the plate and final adjustments. Based on this, the times (in minutes and seconds) required to perform the clinical and laboratory steps were analyzed. Data were statistically evaluated by T, ANOVA and Tukey tests using the Statistical Package for Social Sciences 22.0 software. Results: There was a statistical difference in the time of interocclusal registration, where MIH (47.94sec) and reed (01:03.01min) were performed in a shorter time when compared to the DAR (03:09.26min) (<0.001 ). The time of the assembly step on the articulator was statistically longer when the registration was performed in MIH and the assembly was performed by lifting the pin on the articulator (01:59.62min), comparing to the DAR (01:07.82min) and the reed (01:07.82min) 01: 06.43min) (<0.001), also showing difference in design (p=0.045) and total time of steps (p=0.033). Conclusion: Within the limitations of the study, it can be stated that using the occlusal palette or registering in MIH demonstrated a shorter clinical time when detected using the RAD technique. Lifting the pin on the articulator led to a longer time to assemble the models, regardless of whether the model was mounted in the horizontal plane or on the camper's table, it increased the time in the CAD step.
