principles of tooth reduction part 2

the type of forces the restoration subjected to include

(a)  

Retention form is correlated to forces directed in an apical, oblique, or horizontal direction.

• True
• False

The Tipping Path is defined as

(a)  

as the area outside the tipping path increases the displacement decreases

• True
• False

Axial grooves is a mean of retention used with

(a)  

Frictional retention between opposing axial surfaces is used with all of the following except

• full veneered crown
• Full metal crown
• 3/4 crown
• Jacket (all ceramic) crown

as the Degree of occlusal convergence increases the retention

(a)  

occlusal reduction should not exceed

(a)  

as the diameter / height ratio increases the retention

(a)  

why Premolars give resistance more than molars
