CIT Pharmacology & Medications in Implantology 4 — Questions and Answers
Question 1: A patient on long-term bisphosphonate therapy requires implant placement. Which complication is of greatest concern?
- Peri-implant mucositis
- Medication-related osteonecrosis of the jaw (MRONJ) (Correct answer)
- Delayed osseointegration
- Increased bleeding risk
Correct answer: Medication-related osteonecrosis of the jaw (MRONJ)
Bisphosphonates suppress osteoclast activity and impair bone remodeling, placing patients at risk for MRONJ following implant surgery.
Question 2: Which analgesic class is generally preferred for post-implant pain management in patients without contraindications due to its anti-inflammatory benefit?
- Opioids
- Acetaminophen alone
- NSAIDs (Correct answer)
- Muscle relaxants
Correct answer: NSAIDs
NSAIDs provide both analgesic and anti-inflammatory effects, making them first-line agents for managing post-implant surgical discomfort.
Question 3: Chlorhexidine gluconate 0.12% mouth rinse is commonly prescribed after implant surgery primarily to:
- Accelerate bone remodeling
- Reduce supragingival plaque and bacterial load (Correct answer)
- Stimulate soft tissue growth
- Prevent dry socket
Correct answer: Reduce supragingival plaque and bacterial load
Chlorhexidine is a broad-spectrum antimicrobial that reduces oral bacterial counts and supports wound healing after implant procedures.
Question 4: A patient taking warfarin needs implant surgery. The PRIMARY pharmacological concern the implantology technician should communicate to the supervising clinician is:
- Risk of allergic reaction to local anesthetics
- Elevated bleeding risk requiring INR evaluation (Correct answer)
- Reduced osseointegration potential
- Increased infection susceptibility
Correct answer: Elevated bleeding risk requiring INR evaluation
Warfarin inhibits vitamin K-dependent clotting factors, and the INR must be assessed and managed before surgical procedures to minimize hemorrhagic complications.
Question 5: Which property makes amoxicillin a common antibiotic choice for prophylaxis in implant procedures?
- Broad-spectrum gram-negative coverage only
- Good oral bioavailability and effectiveness against oral streptococci (Correct answer)
- Ability to penetrate biofilm without bone
- Antifungal activity
Correct answer: Good oral bioavailability and effectiveness against oral streptococci
Amoxicillin has high oral bioavailability and covers the streptococcal and anaerobic organisms most relevant in oral surgical prophylaxis.
Question 6: Corticosteroids are sometimes used peri-operatively around implant surgery to:
- Prevent implant rejection
- Reduce postoperative swelling and trismus (Correct answer)
- Promote faster osseointegration
- Eliminate the need for antibiotics
Correct answer: Reduce postoperative swelling and trismus
Corticosteroids suppress the inflammatory cascade, reducing edema and trismus that can accompany extensive implant surgeries.
Question 7: A patient reports taking selective serotonin reuptake inhibitors (SSRIs). Research suggests SSRIs may affect implant outcomes by:
- Promoting faster bone growth
- Impairing osseointegration through reduced osteoblast activity (Correct answer)
- Increasing risk of allergic reaction to titanium
- Decreasing postoperative infection risk
Correct answer: Impairing osseointegration through reduced osteoblast activity
Studies indicate SSRIs may negatively influence bone metabolism via serotonin receptor activity on osteoblasts, potentially lowering implant survival rates.
