Tattered occlusion where lots of mod flat amalgams and you really don't have a much of a bite to grasp onto would you agree that perhaps that patient will be more susceptible absolutely i mean it's the same thing is when we discuss sort of people with the risk of an anterior open bite. If they've got good cuspid to foster contacts at the back chances are they're not going to lose mip when you get rid of one centric relation contact point or they'll find something that is close enough so yeah the risk is pretty low.

Episode notes
Have you ever prepared the last molar for a crown? And just when you check the occlusal reduction, the patient bites down and as if by magic, the reduction has all DISAPPEARED?! It is the phenomenon that we call ‘The Last Tooth in the Arch Syndrome’
This episode with Dr. Mahmoud Ibrahim will give you more confidence in recognizing, screening, and managing such complications in practice. But like I say in the main episode, optimistically, this phenomenon will never happen to you AGAIN if you follow these protocols for screening.
Protrusive Dental Pearl: Watch out for the patient with quite flat teeth as they are more susceptible to the last tooth in the arch syndrome / bite change. They do not have good posterior coupling/stability and therefore more likely to ‘forget’ their bite as the cuspal inclines do not guide the mandible back in to maximum intercuspation.
