CDC Patient Assessment & Documentation 4

Question 1

A ceramist notices the prescription lists 'prep finish line: deep chamfer at 1.2 mm.' Which ceramic material system is this preparation most compatible with?

Accepted Answer

Full-contour zirconia, lithium disilicate, or other all-ceramic systems requiring adequate ceramic bulk

Answer

A deep chamfer at 1.2 mm provides adequate space for all-ceramic systems that require minimum ceramic thickness for strength.

Question 2

When assessing shade photographs provided by the clinician, which lighting condition is considered most accurate for shade documentation?

Accepted Answer

Natural daylight or calibrated daylight-balanced photographic lighting

Answer

Natural or calibrated daylight-balanced lighting provides the most accurate color rendition for shade documentation and ceramist communication.

Question 3

A patient's record shows a crown-to-root ratio of 1:1 on the planned abutment tooth. How should this influence the ceramist's documentation and design?

Accepted Answer

It signals that occlusal load reduction and careful emergence profile design are important to minimize leverage on the compromised root

Answer

A 1:1 crown-to-root ratio indicates reduced periodontal support, so the ceramist should minimize lateral forces and optimize contours to protect the abutment.

Question 4

In digital patient assessment workflows, what is the primary advantage of using intraoral scan files (.STL) over traditional PVS impressions for ceramist documentation?

Accepted Answer

Digital scans eliminate impression distortion, allow remote communication, and can be directly milled or printed

Answer

Digital scans avoid material distortion, enable instant electronic transfer, and integrate with CAD/CAM systems for precise ceramic fabrication.

Question 5

A prescription documents the patient's occlusal plane as 'canted 3° to the left.' What should the ceramist do with this information?

Accepted Answer

Document it and communicate with the dentist about whether the restorations should correct the cant or follow the existing plane

Answer

An occlusal cant requires explicit communication between the ceramist and dentist to decide whether restorations should accommodate or correct the discrepancy.
