CDC Patient Assessment & Documentation 5

Question 1

A complete patient record for a full-mouth ceramic reconstruction should include which of the following pre-treatment records?

Accepted Answer

Full series radiographs, diagnostic casts mounted in CR, photographs, and periodontal charting

Answer

Comprehensive reconstruction requires a full diagnostic workup including radiographs, CR-mounted casts, photographs, and periodontal records to guide ceramic design.

Question 2

When a patient's prescription documents 'diastema closure requested' between teeth #8 and #9, what esthetic consideration must the ceramist document?

Accepted Answer

The width-to-length ratio and midline position must be carefully planned to avoid disproportionate crown dimensions

Answer

Closing a diastema adds width to the crowns, so the ceramist must plan proportions carefully to maintain natural-looking width-to-length ratios and proper midline alignment.

Question 3

A patient's record notes 'Angle Class I with anterior deep bite (overbite 6 mm).' How does this affect ceramic incisal design?

Accepted Answer

It requires careful attention to palatal ceramic thickness and incisal edge anatomy to avoid fracture under heavy anterior loading

Answer

A deep bite creates high shear forces on anterior ceramic restorations, requiring adequate palatal bulk and strong ceramic materials to resist fracture.

Question 4

During documentation review, a ceramist notes that the working impression was taken with polyether material. What characteristic of polyether is clinically relevant to ceramic case accuracy?

Accepted Answer

Polyether absorbs water and can distort if stored in moist environments, affecting die accuracy

Answer

Polyether is hydrophilic and will absorb water if stored in a humid environment, leading to dimensional distortion and inaccurate dies.

Question 5

A patient assessment documents 'gingival recession of 2 mm on teeth #6 and #11.' This finding most directly influences ceramic design by:

Accepted Answer

Affecting the planned margin location and requiring careful root surface contour design to avoid food traps

Answer

Recession means exposed root structure at the margin, requiring the ceramist to design contours that are cleansable and do not trap plaque at the root-restoration interface.
