Posselt's Envelope of Movement

    Hey everyone!

Posselt's Envelope is a guide for dentists to measure, observe and guide the different mandibular movements a person can do. It shows every movement possible and the relationship they have with one another.

   It includes movements such as: 

• Retruded Contact Position (RCR)

• Intercuspal Position (ICP)

• Edge to Edge

• Maximum Protrusion 

• Minimal Opening or Mandibular opening with the condylar heads still in the glenoid cavity.

• Maximal Opening or the translation of the condylar heads. 

• Lateral Movements

These movements will be emphasized and explained in the next post of this blog. Meanwhile, you can check out this video which tells you a little bit about Posselt's envelope!

Thank you! Stay alert for the next post!
