Video commentary excerpt
Summary of morpho-functional diagnosis, the mandible is in a physiological rest position:
This is a symmetrical face:
1. the morphology of the skeletal bases: The cranial base, maxilla and mandible are symmetrical in themselves and normal size.
2. Positional study of the skeletal bases including:
The maxillary coincides with the skull, the insertion base of the superior labial frenulum is perpendicular to the paramedian sagittal plane. The maxillary coincides with the skull, the insertion base of the inferior labial frenulum is perpendicular to the paramedian sagittal plane
3. Study of mandibular function: In the posterior, there is associated bilateral condyle-disc coaptation. from PR IOM deviation of the mandible on the left with the left representing a cross bite and lateral retro and left mandibular supraposition which results in an offset hinge axes (purple color, so that predisposed to dysfunction) compared to the original green axes. The mandibular condyles are in pure rotation. The vertical and sagittal mandibular condyles axes "hinges" located at their medial poles are purple. They represent the alternating condylar axis rotations in three-dimensional movements. On the right side, a lateral pro and right mandibular infraposition, the rotation is at the inner pole of the right condyle.
