ABSTRACT

The registration of the inhibitory reflex of the masseter muscle (reflexigram, RFXG) it has shown to be an useful tool in the functional evaluation of the generating mechanisms and regulators of the mastication. The purpose of the present work was to determine what changes are present in the RFXG in patients after the use of a Michigan bite plate model and to discuss which could be the physiologic implications of the same ones. The initial registration showed the neuromuscular state of the subjects before placing the bite plate, the subsequent registrations showed the changes present when using the bite plate, finding these toward what has been described as normal. When studying the RFXG we could determine the area of inhibition, the relationship that exists among the potentiation area with regard to the inhibition area, and we compared the symmetry among the right and left side. Su we could value this way to the inhibitory reflex of the masseter muscle and to determine the presence of some alteration in this reflex, as well as the changes that happened after the use of the bite plate, verifying the evolution of this reflex. The right and left masseter muscles were registered by means of the technique of RFXG broadly described in previous works before and after the use of bite plates. The average underwent the routine statistical test of kweness and curtosis, As the values of the variables of the registrations were not distributed according to the normal curve, to evaluate correlations they were carried out the non parametric tests of Spearman and of Wilcoxon. to value the relationships and differences of the same ones. The results indicate that the mechanisms of neurofunctional control in the subjects studied presented differences regarding the normal before the use of the bite plates, that tend to be reverted with the placement of this bite plates and that this can be evaluated by means of the RFXG.
