a) leaving the space will eventually cause a problem in every patient

b) the longer he waits to fill this space the easier it will be

c) while he may have no chewing problems now, chewing problems are likely to occur in the future

d) filling the space is primarily an esthetic concern

Answer 1

C

Question 2

When compared to a 3-unit bridge, a 4-unit bridge has the following concerns:

a) the 4-unit bridges deflection under occlusal load is directly proportional to its length

b) the 4-unit bridge connector height is directly proportional to its deflection

c) the 4-unit bridge connector height should be less in the 3-unit bridge to allow for proper anatomy

d) there is on difference between the forces on the abutments between the two bridges from occlusion

Answer 2

A

Question 3

Please choose the correct answer concerning pier abutments:

a) pier abutments are successful because the retention of the retainers is very similar on each abutment

b) per abutments are successful because occlusal forces help stabilize the prosthesis

c) a non-rigid connector if used, is best placed on the distal side of the middle abutment

d) pier abutments are successful because decay issues are easily remedied and addressed

Answer 3

C

Question 4

Which of the following are true concerning preparing and manufacturing a fixed partial denture using a tipped molar?

a) the occlusal forces on a bridge abutment that has been placed on a tipped molar are the same as non-tipped molar

b) the long axis of the tipped molar should be no more than 40 degrees as a maximum angle between the two abutments

c) with a first tipped molar, often the second molar is tipped as well and therefore is a consideration for the first molar crown preparation

d) the crown preparation for a tipped molar and a non-tipped molar are the same to ensure retention and resistance

e) all answers are correct

Answer 4

C
