Dental Implants Patient Assessment & Treatment Planning

Question 1

Which imaging modality is considered the gold standard for implant treatment planning in the US?

Accepted Answer

Cone Beam CT (CBCT)

Answer

CBCT provides three-dimensional data of bone volume, density, and proximity to vital structures essential for accurate implant planning.

Question 2

Uncontrolled Type 2 diabetes is considered a relative contraindication for dental implants primarily because:

Accepted Answer

It impairs immune response and wound healing, increasing failure risk

Answer

Elevated HbA1c levels correlate with impaired osseointegration, increased infection risk, and delayed healing around implants.

Question 3

What is the minimum residual bone height above the mandibular canal recommended before implant placement in the posterior mandible?

Accepted Answer

2 mm

Answer

A minimum of 2 mm safety margin above the inferior alveolar nerve canal is required to prevent nerve injury during implant placement.

Question 4

Bisphosphonate use is a significant concern for implant patients because it can cause:

Accepted Answer

Medication-related osteonecrosis of the jaw (MRONJ)

Answer

Bisphosphonates suppress bone turnover and can lead to MRONJ, particularly after dentoalveolar surgery including implant placement.

Question 5

Which ASA classification represents a patient with well-controlled systemic disease and is generally considered a safe implant candidate?

Accepted Answer

ASA II

Answer

ASA II patients have mild systemic disease that is well-controlled, posing minimal additional surgical risk for implant procedures.
