Question 1

When a patient is allergic to penicillin, which antibiotic is a common alternative for prophylaxis in implant surgery?

Accepted Answer

Clindamycin

Answer

Clindamycin provides coverage against gram-positive and anaerobic oral organisms and is the standard penicillin-allergy alternative in dental surgical prophylaxis.

Question 2

Epinephrine is added to local anesthetics used during implant surgery primarily to:

Accepted Answer

Prolong anesthetic duration and reduce systemic absorption

Answer

Epinephrine causes local vasoconstriction, slowing anesthetic absorption into the bloodstream and extending the duration of the block while reducing bleeding.

Question 3

A patient using proton pump inhibitors (PPIs) long-term is at risk for implant complications primarily because PPIs can cause:

Accepted Answer

Reduced calcium absorption leading to lower bone density

Answer

Long-term PPI use reduces gastric acid-mediated calcium absorption, potentially decreasing bone mineral density and impairing osseointegration.

Question 4

Which local anesthetic has the longest duration of action and is often used for prolonged implant procedures or postoperative analgesia?

Accepted Answer

Bupivacaine

Answer

Bupivacaine has a significantly longer half-life than other dental local anesthetics, providing extended numbness useful for lengthy or painful implant surgeries.

Question 5

Metronidazole is sometimes combined with amoxicillin for implant-related infections because metronidazole specifically targets:

Accepted Answer

Obligate anaerobic bacteria

Answer

Metronidazole is selectively effective against obligate anaerobes, complementing amoxicillin's spectrum for polymicrobial peri-implant infections.
