| Resumo: | 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 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. |
