PASSIVE

Question 29

What are the three indicators for using a hybrid prosthesis?

You can cantilever a hybrid denture 1.5x the A-P spread of the most anterior implant to the most posterior implant

Question 31

According the to the English AP spread, if I have 8mm of AP in the anterior how much can I cantilever past the most posterior implant?

Answer 31

12mm past the most posterior implant....(8mm x 1.5 = 12mm)

So the English AP spread is for the minimum amount of cantilever, what is the maximum amount?

Answer 33

AP spread x 2 (vs English = AP spread x 1.5)

Question 34

In this patient a combination of excessive cantilever length and insufficient A-P spread lead to implant _______ and a _______ remodeling response of the adjacent bone.
