|
Which ridges bear very little pressure?
|
Maxillary and Mandibular Anterior Ridges
|
|
|
Which portion of the ridges is best at withstanding pressure?
|
The posterior ridges due to the composition of the bone in that area

Where is the snow shoe effect?
|
In the posterior area it spreads out the pressure

it will move from 1-3 mm |
|
|
Which Kennedy Classifications are Real Partial Dentures?
|
K1 and K2
|
|
|
Which Kennedy Classifications are considered the most difficult to make?
|
K1 and K2 are the most difficult because they have movement

|
Viscoelasticity
|
|
|
What is viscoelasticity?
|
There is an initial compression of the tissue, then a few minutes later, there is a second compression
|
|
|
