Mandible Dislocation and Tmj Pathology Flashcards
How does mandible dislocation(luxation ) happen and in which compartment of the joint ?
When widely open the mandible , the disc and head of condyle move forward so far they slip out of the articular fossa and move forward beyond the articular eminence .
Upper joint compartment where the translation occurs .
When does lock open happen ?
When the mandible condyle come off of the disc , causing the jaw to lock open .
If the closing muscles suddenly contract the mandible could become painfully locked open .
What will happen if the closing muscles suddenly contract ?
If the closing muscles suddenly contract the mandible could become painfully locked open .
Jaw opening muscles are not nearly as powerful as the closing muscles , and therefore we may not be able to unlock a mandibular dislocation in our own mouth without help .
