Video commentary excerpt
The mandible is in a physiological rest position (RP):
In this rest position, the electromyographic activity of the upper lateral pterygoid (inserted on the disc and on the neck of the mandibular condyle is important.
The elevator muscles are:
• temporal: predominance of anterior fibers
• the medial pterygoid muscles
• the superficial masseter muscles, medium and deep
To cover all mandibular movements represented by the triagramme of Posselt and and a complete condylar triaxiogramme THE VIDEO reproduces the four cycles of the mandibular movement
1. Open - close
2. Propulsion - retro-pulsion
3. Left-sided - propulsion - right sided
4. Left-sided - opening - right sided
5. Full Posselt in 3-D
