CIT Patient Assessment & Clinical Evaluation 3

Question 1

Which Misch bone density classification describes dense cortical bone with little medullary bone, typically found in the anterior mandible?

Accepted Answer

D1

Answer

D1 bone is the densest classification, consisting primarily of cortical bone and most commonly found in the anterior mandible.

Question 2

A patient has a history of head and neck radiation therapy. Which specific concern must be evaluated before implant placement?

Accepted Answer

Osteoradionecrosis risk due to hypovascular, hypoxic bone

Answer

Radiation damages blood vessels and reduces bone's healing capacity, making osteoradionecrosis a primary risk in irradiated jaw bones.

Question 3

What does the Eichner Index classify in the context of pre-implant patient assessment?

Accepted Answer

The degree of occlusal support based on remaining tooth contacts

Answer

The Eichner Index categorizes patients by the number of opposing occlusal contacts, informing the extent of prosthetic support needed.

Question 4

When evaluating interarch space for an implant-supported crown, what is the generally accepted minimum vertical restorative space required?

Accepted Answer

7–8 mm

Answer

A minimum of 7–8 mm of vertical restorative space is typically required to accommodate an implant abutment and crown.

Question 5

A patient with bruxism is being evaluated for implants. Which assessment finding would most directly influence treatment planning to mitigate implant overload?

Accepted Answer

Wear facets on opposing teeth indicating parafunctional forces

Answer

Wear facets confirm parafunctional activity, indicating the need for an occlusal guard and modified prosthetic design to protect implants from overload.
