Video commentary excerpt
The movement of the opening is performed with:
• In the anterior, the inferior labial frenum is shifted left relative to the superior
• At the start of this opening at the condylar the axis hinges are still dysfunctional.
• The points corresponding to the PR and IOM at the condylar remain confused as we are in pure condylar rotation, this translates into a vertical displacement at the incisive level
• By discal luxation the mandible deviates to the left, on the affected side until recovery of the disk from the left condyle
• The axe hinges become functional again, parallel, until the POM where the two discs cap the condylar heads and the labial frenum coincide with each other and with the PSM
