,Q1 APPLY ADVANCED SURGICAL AND PROSTHETIC PRINCIPLES TO COMPLEX IMPLANT
CASES
A patient on long-term bisphosphonate therapy requires implant placement. Which
laboratory value is most critical to assess prior to surgery to minimize the risk of
medication-related osteonecrosis of the jaw (MRONJ)?
A. Serum calcium
B. C-terminal telopeptide (CTX) level CORRECT
C. Alkaline phosphatase
D. Parathyroid hormone
RATIONALE: CTX is a bone resorption marker used to gauge the relative risk of MRONJ; levels
<150 pg/mL indicate high risk. Serum calcium and PTH assess calcium metabolism, not bone
turnover. Alkaline phosphatase reflects osteoblastic activity but is not the standard risk indicator
for MRONJ.
Q2 APPLY ADVANCED SURGICAL AND PROSTHETIC PRINCIPLES TO COMPLEX IMPLANT
CASES
In a sinus augmentation procedure, which graft material is most appropriate for a
patient with a large sinus membrane perforation and a history of chronic
sinusitis?
A. Autogenous bone from the iliac crest
B. Anorganic bovine bone mineral (ABBM)
C. Demineralized freeze-dried bone allograft (DFDBA)
D. Recombinant human bone morphogenetic protein-2 (rhBMP-2) on an absorbable collagen
sponge CORRECT
RATIONALE: rhBMP-2 is an osteoinductive growth factor that does not require a particulate
scaffold and is less likely to become infected in a compromised sinus. Autogenous bone and
ABBM are particulate and may migrate through a perforation. DFDBA has variable osteoinductive
potential and also poses infection risk.

,Q3 APPLY ADVANCED SURGICAL AND PROSTHETIC PRINCIPLES TO COMPLEX IMPLANT
CASES
Which of the following best explains the higher osseointegration success of
implants with a sandblasted, acid-etched (SLA) surface compared to machined
surfaces?
A. Increased surface area and enhanced fibrin clot retention CORRECT
B. Higher surface hydrophobicity
C. Reduced platelet activation
D. Lower surface roughness leading to less bacterial adhesion
RATIONALE: SLA surfaces have increased micro-roughness, which enlarges the surface area for
bone-implant contact and promotes fibrin scaffold retention, facilitating osteoblast migration.
Hydrophilicity, not hydrophobicity, is beneficial. Platelet activation is enhanced, not reduced.
Roughness increases bacterial adhesion, but this is secondary to osseointegration.
Q4 APPLY ADVANCED SURGICAL AND PROSTHETIC PRINCIPLES TO COMPLEX IMPLANT
CASES
A patient presents with peri-implantitis and significant crestal bone loss. Which
treatment sequence is most evidence-based for initial non-surgical management?
A. Mechanical debridement with titanium curettes and chlorhexidine irrigation CORRECT
B. Systemic antibiotics without mechanical debridement
C. Immediate surgical flap with bone grafting
D. Laser therapy alone
RATIONALE: Non-surgical mechanical debridement using instruments softer than the implant
surface (titanium or plastic) plus antimicrobial irrigation is the first-line treatment. Systemic
antibiotics alone are ineffective without debridement. Surgical intervention is reserved after failed
non-surgical therapy. Laser monotherapy lacks sufficient evidence.

, Q5 APPLY ADVANCED SURGICAL AND PROSTHETIC PRINCIPLES TO COMPLEX IMPLANT
CASES
Which of the following best describes the primary biomechanical advantage of a
platform-switched implant connection?
A. Increases the diameter of the abutment to reduce stress on the bone
B. Moves the implant-abutment junction medially, reducing crestal bone stress CORRECT
C. Eliminates microgap completely
D. Enhances the strength of the implant-abutment connection
RATIONALE: Platform switching uses a smaller-diameter abutment on a larger implant platform,
shifting the inflammatory infiltrate and stress concentration away from the crestal bone, thereby
preserving marginal bone. It does not increase abutment diameter or eliminate the microgap. It
may weaken the connection but that is not the primary biomechanical advantage.
Q6 APPLY ADVANCED SURGICAL AND PROSTHETIC PRINCIPLES TO COMPLEX IMPLANT
CASES
Which of the following is a critical contraindication for immediate implant
placement into an extraction socket?
A. Presence of a buccal bone dehiscence
B. Thin gingival biotype
C. Acute infection with purulent drainage CORRECT
D. Previous orthodontic treatment
RATIONALE: Acute infection with purulence is a contraindication due to high risk of implant
failure. Buccal dehiscence and thin biotype are manageable with grafting and soft tissue
techniques. Previous orthodontics is not a contraindication.
