Morpho-functional diagnostics summary
This is a symmetric face: The mandible is in a physiological rest position.
1. The morphology of the skeletal bases:
• The cranial base, maxillary and mandibular are symmetrical in themselves and normal in size, the anatomy of the structures of the Temporomandibular joint is symmetrical.
• A tip on the top left of the maxillary frontal occlusal plane.
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 mandible has a high tip to the left and back in relation to the skull, this tipping is due to the left discal ante-medioposition that we will detail further below
3. Study of mandibular function:
• Recall that the previous reference point chosen must be bone and not dental. it is obtained by the intersection between the horizontal insertion base of the lower labial brake and its mediator.
• The inferior labial frenum is shifted left relative to the superior This is due to the muscle spasm on that side, causing a lateral retro left mandibular supraposition associated with an offset of the axe hinges (red, so dysfunctional) compared to the hinges of the originally green axes.
• On the right side, there is a slight lateral mandibular right pro and infraposition. Rotation is at the inner pole of the right condyle ...
• The difference with the reducible and irreducible disc dislocations lies in ...
