Answer 19

• C:R ratio
• Mobility
• Alveolar bone support
• Root configuration
• Angulation
• Opposing occlusion
• Pulp condition
• Presence of endo treatment

Question 20

Periodontally compromised dentition is defined as

Answer 20

-relationship of the tooth with alveolar bone compared with the portion not withinthe alveolar bone

Fulcrum of the abutment tooth is a class _ lever

Answer 21

I

Question 22

T/F Most roots are conical

Answer 22

t

Question 23

How can the CRR be improved
