Module 5

Question 1

What information can be obtained form completing diagnostic tooth preps and diagnostic casts?

Answer 1

Selecting appropriate path of placement for an FPD - especially when abutment teeth are tilted or have atypical coronal contour
Deciding on the amount of tooth reduction necessary to accomplish a planned change in the occlusion

Question 2

What are diagnostic waxing useful for?

Answer 2

Pts teeth need adjustments for optimal contour
Establish optimum contour and occlusion of eventual prosthesis
Determining Ideal occlusion
Evaluate axial alignment of tooth preps

Question 3

What is the significance of the diagnostic wax-up and denture tooth set-up in the decision making procedure for complex prosth patients?

Answer 3

Complex decisions as to the best combo of tooth prep and POP can be simplified via diagnostic prep, waxing, and denture tooth setting
Aid in determining how to achieve the best mechanical and esthetic result without deviating from principles of occlusion or making excessively bulky restorations that can lead to periodontal complications
Determine precise endpoint occlusion and appearance with interchangeably articulator-mounted casts of the pretreatment and post-treatment condition
Enables treatment sequence to be simplified by allowing one arch at a time
Valuable in pts who require a combo of fixed and removable

Question 4

What are the 5 treatment descriptions that would require the complex diagnosis?

Answer 4

4 or more fixed restorations
RPD
Immediate denture opposed by natural teeth
FPD
Implant restoration
