CCE Preliminary & Diagnostic Work Up 4

Question 1

What is the purpose of a phonetic evaluation during the preliminary diagnostic work-up for anterior ceramic restorations?

Accepted Answer

To determine proper incisal edge position by observing tooth display during 'F,' 'V,' and 'S' sounds

Answer

To assess the patient's psychological readiness for treatment

Answer

To measure vertical dimension using a phonetic ruler

Answer

To identify patients who need speech therapy before treatment

Question 2

During the diagnostic work-up, a ceramist reviews the patient's smile photographs and notes excessive gingival display. This finding primarily influences:

Accepted Answer

Whether crown lengthening or gingival recontouring is needed before restorations are placed

Answer

The number of ceramic units to be fabricated

Answer

The firing temperature of the ceramic

Answer

The choice between zirconia and lithium disilicate

Question 3

Which of the following is an important consideration when reviewing periapical radiographs during pre-ceramic diagnostic evaluation?

Accepted Answer

Root length, bone levels, and periapical pathology that could compromise restoration longevity

Answer

The radiograph brand used by the dental office

Answer

Whether the patient has had previous orthodontic treatment

Answer

The kVp settings used during exposure

Question 4

In a diagnostic work-up, the ceramist receives casts that have been mounted in maximum intercuspation (MIP) rather than centric relation (CR). The primary limitation of this mounting is:

Accepted Answer

MIP may not represent the most stable condylar position, potentially leading to occlusal discrepancies in the final restorations

Answer

The casts cannot be used for shade selection

Answer

The articulator will not accept MIP-mounted casts

Answer

Wax-up material adheres poorly to MIP-mounted casts

Question 5

When evaluating a patient for ceramic anterior restorations, what does the 'E' test determine?

Accepted Answer

The amount of incisal tooth display at rest by asking the patient to say 'E'

Answer

Enamel thickness using transillumination

Answer

Erosion depth using an explorer probe

Answer

The electrolyte content of saliva

Question 6

Before beginning a diagnostic wax-up for a patient with a Kennedy Class I removable partial denture, the ceramist should consider:

Accepted Answer

How the planned ceramic restorations will interact with the RPD framework rests and clasps

Answer

Whether the patient prefers acrylic or porcelain denture teeth

Answer

The age of the existing RPD

Answer

Whether the patient's insurance covers ceramic restorations

Question 7

A ceramist receives a case with no written prescription or shade map. The best course of action is to:

Accepted Answer

Contact the restorative dentist to obtain complete case documentation before starting any work

Answer

Proceed with fabrication using a default shade of A2

Answer

Use the opposing cast shade as a guide

Answer

Begin wax-up and request shade information later
