CDC Patient Assessment & Documentation 3

Question 1

A patient's record indicates a 'Class II centric relation to centric occlusion slide of 2 mm.' What should a ceramist note about this finding?

Accepted Answer

Restorations may need to accommodate a CO-CR discrepancy, potentially requiring articulator-mounted casts in CR

Answer

A significant CR-CO slide means casts should be mounted in centric relation to ensure restorations are fabricated in the correct jaw position.

Question 2

Which patient factor documented in the medical history is most likely to affect the color stability of ceramic restorations over time?

Accepted Answer

Regular consumption of chromogenic foods and beverages and tobacco use

Answer

Chromogenic dietary habits and tobacco use can stain ceramic surfaces, particularly affecting glazed surfaces or any surface roughness over time.

Question 3

Documentation shows the patient has a 'narrow biologic width' with only 1 mm of attached gingiva. This affects ceramist planning by:

Accepted Answer

Influencing subgingival margin depth and emergence profile design to avoid tissue inflammation

Answer

Narrow attached gingiva means the ceramist must design a physiologic emergence profile that avoids impinging on the biologic width.

Question 4

On a lab prescription, the dentist notes 'open contacts in the posterior sextants.' How does this affect the ceramist's approach?

Accepted Answer

The ceramist should note this but contact points must be established on the new restoration

Answer

Open contacts documented elsewhere alert the ceramist to ensure the new restoration establishes appropriate proximal contacts to prevent food impaction.

Question 5

What is the purpose of documenting the patient's Frankfort horizontal plane in cephalometric records?

Accepted Answer

To serve as a reference plane for evaluating facial proportions and tooth position

Answer

The Frankfort horizontal plane is a standard craniofacial reference used to assess facial balance and incisal plane orientation.
