CCE Preliminary & Diagnostic Work Up 5

Question 1

When assessing a patient's smile for ceramic restoration planning, what is the significance of the 'commissure line'?

Accepted Answer

It helps determine the esthetic width of the smile and how many teeth should be visible

Answer

The commissure line drawn between the corners of the mouth helps the ceramist determine how many teeth will be visible in a full smile and guides arch width design.

Question 2

In the preliminary work-up, which of the following best describes 'occlusal plane analysis'?

Accepted Answer

Evaluating the orientation of the biting surface relative to a reference plane such as the ala-tragus line

Answer

Occlusal plane analysis compares the existing or planned occlusal plane to facial reference planes to ensure the ceramic restorations will appear level and harmonious.

Question 3

A patient scheduled for ceramic crown restorations is found to have active periodontal disease during the preliminary work-up. What is the appropriate action?

Accepted Answer

Complete periodontal therapy and achieve stability before fabricating any ceramic restorations

Answer

Active periodontal disease must be treated and tissue must be stable before ceramic restorations are placed, as inflamed tissue levels will change after treatment.

Question 4

During a diagnostic evaluation for ceramic veneers, the patient shows evidence of gastric acid erosion on lingual tooth surfaces. This finding suggests the ceramist should:

Accepted Answer

Advise the restorative team to coordinate with medical care to control acid exposure before and after restoration

Answer

Acid erosion from gastric reflux will continue to degrade tooth structure and restoration margins unless the underlying medical condition is managed alongside dental treatment.

Question 5

What is the primary purpose of a 'preliminary impression' versus a 'final impression' in the context of diagnostic work-up?

Accepted Answer

Preliminary impressions are taken with irreversible hydrocolloid to make study casts for diagnosis and treatment planning, not for fabricating final restorations

Answer

Preliminary (study) impressions, typically taken with alginate, are used to create diagnostic casts for analysis and planning, while final impressions use more accurate elastomeric materials for restoration fabrication.
