RECORDING OF MASTICATION ANGLES BY PLANAS’S LAWS Figure 1. Masticatory angles on patients with the vertical masticatory stereotype MATERIAL AND METHOD The analysis of the masticatory function has been performed on one group of 20 students from the University School of Dentistry – Timisoara. Given the large number of techniques used for the determination of the functional masticatory angles, we chose the one proposed by Planas, because it is the most practical and simple. Here are the steps of the clinical procedure: The patients’ teeth are in close contact, in maximal intercuspation. The dentist uses tweezers in order to locate the reference point. The reference point is situated on the junction of the lower incisors medial line and the free edge line of the upper incisors. This point will be marked with a waterproof marker. From the occlusal maximal intercuspation, the mandible glides laterally left and right, (maintaining partial teeth contact), until an edge to edge or canine cusp to canine cusp (when the guidance is antero-lateral, canine) position is obtained. The trajectory of the reference point will be carefully observed during lateropulsion, highlighting any deviations from the trajectory caused by interferences. STOMA.EDUJ (2014) 1 (2) The digital images of the masticatory angles, relevant to pathological aspects, allow us to determine the values of the angles on the computer. When differences between the two angle values (left and right) appear, the patient will prefer to masticate on the side where the value of the angle is smaller. RESULTS After analysing the masticatory angles (left, right) on a group of 40 students, we have concluded: Different values of the left and right angle
