ORAL PHYSIOLOGY Figure 2. Masticatory angles on patients with the horizontal masticatory stereotype intermediary aspects, where the masticatory angles are symmetric only in 32% of cases and asymmetric in 68% of cases. Although the trajectory can vary significantly, the start and stop positions of the mandible always match one another. Therefore we must underline the fact that terminal phase is guided by the dental articular surfaces, starting from the first dental contact until the maximal intercuspation is realized. This position corresponds to the minimal vertical dimension, therefore interferences can be palpatorily detected. The assessment and comparison of the values of the two angles provide us with useful information about how our patients perform the basic function of the stomatognatic system, namely mastication. The data obtained reveal a remarkable fact, namely that 93% of the cases present modification of the masticatory function. Figure 1. and 2. show us the differences between the two masticatory angles on two types of patients, one with a vertical masticatory stereotype and the other one with a horizontal masticatory stereotype. 88 Patients present problems, such as: unresolved dento-maxillar anomalies in their childhood or adolescence, edentulous without prostheses, odontal, periodontal and prosthetic defective treatments (defective reconstruction of dental morphology), etc. Such problems create at least partial masticatory insufficiencies which have long term consequences. We think that the existence of a large number of patients with the vertical masticator stereotype in their young ages is a result of the eating habits (fast food – hamburgers, which is not stimulating enough). On the other hand, some ethnic groups of the Banat population raise the question of a genetic determinant in this area. DISCUSSION For the neuro-oclusal rehabilitation it is essential to analyse the functional masticator angles. This analysis should be done for all patients because it provides us with most of the information about their masticatory function. Planas’s philosophy starts with the mandible bone development and it is in close correlation with the dynamics of temporomandibular joint. STOMA.EDUJ (2014) 1 (2)
