Dental Implants Patient Assessment & Treatment Planning 1 — Questions and Answers
Question 1: Which imaging modality is considered the gold standard for implant treatment planning in the US?
- Periapical radiograph
- Panoramic radiograph
- Cone Beam CT (CBCT) (Correct answer)
- MRI
Correct answer: Cone Beam CT (CBCT)
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:
- It causes teeth to fall out faster
- It impairs immune response and wound healing, increasing failure risk (Correct answer)
- Diabetic patients cannot tolerate anesthesia
- High glucose destroys titanium implants
Correct answer: It impairs immune response and wound healing, increasing failure risk
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?
- 1 mm
- 2 mm (Correct answer)
- 5 mm
- 10 mm
Correct answer: 2 mm
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:
- Implant corrosion
- Medication-related osteonecrosis of the jaw (MRONJ) (Correct answer)
- Excessive bone overgrowth around implants
- Implant rejection
Correct answer: Medication-related osteonecrosis of the jaw (MRONJ)
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?
- ASA I
- ASA II (Correct answer)
- ASA III
- ASA IV
Correct answer: ASA II
ASA II patients have mild systemic disease that is well-controlled, posing minimal additional surgical risk for implant procedures.
Question 6: Smoking affects dental implant outcomes by:
- Accelerating osseointegration
- Reducing implant survival rates and increasing peri-implantitis risk (Correct answer)
- Improving blood supply to the site
- Having no significant effect on outcomes
Correct answer: Reducing implant survival rates and increasing peri-implantitis risk
Smoking reduces vascularity, impairs immune function, and increases bacterial colonization, significantly raising implant failure and peri-implantitis rates.
