SARPE limitation
Coronoid process
28
Things to know about Twin Block

34
What nerve provides special sensory - taste to the tongue?
Anterior 2/3 - Chorda Tympani of VII (Facial) | Posterior 1/3 - Glossopharyn)geal Nerve (IX)
35
What nerve provides motor function to the tongue
XII (Hypoglossal)
36
Which nerve ends at 1/3 of anterior tongue?
Lingual nerve
37
Which cyst is associated with a congenitally missing tooth but arises from dental lamina?

T/F, Measuring papilla levels to bone is predictable. It should be 5 mm from contact to alveolar crest of bone
True | True
42
T/F, There is an inversely proportional distance between contact and bone. In other words, the greater the distance, the smaller the chance of papilla

What things are related to succesful TAD placement
Direction of force Amount of force Cortical bone thickness
47
What two things increase primary stability of a TAD
Thickness of cortical bone | Width or diameter of the TAD
48
Which is not acceptable record to evaluate an ortho patient with perio problems?
