Question 3

What are advantages of anatomic teeth?

Answer 3

• Penetrate food more easily
• Can resist movement by interdigitation
• Easier to achieve balance
• Better esthetics

Question 4

What are disadvantages of anatomic teeth?

Answer 4

• little tolerance in their articulation, requiires an exacting technique
• Require clinical remount procedure for occlusal correction

Question 5

What are advantages of non-anatomic teeth?

Answer 5

• Does not lock mandible into one position
• Permits use of a simpler technique
• Minimize horizontal pressures because of absence of inclined planes
• permit closure in >1 position
• Easily adapted to Class II and III
• Occlusal corrections are easier to accomplish
