,Q1 CRITICALLY EVALUATE IMPLANT TREATMENT PLANNING BASED ON EVIDENCE-BASED
CRITERIA
A patient presents for implant placement in the posterior maxilla. CBCT reveals a
residual bone height of 4 mm and width of 6 mm. Which surgical approach best
addresses the anatomical limitations while maintaining implant survival rates
comparable to native bone?
A. Ultrasonic piezoelectric surgery with crestal sinus lift and simultaneous implant placement
using a tapered implant
B. Lateral window sinus augmentation with particulate graft and delayed implant placement after
9 months CORRECT
C. Short implant placement (6 mm) without grafting to minimize morbidity
D. Osteotome-mediated sinus floor elevation with immediate implant placement and platelet-rich
fibrin
RATIONALE: With only 4 mm residual height, a lateral window approach with delayed placement
is the most predictable for achieving adequate bone volume and high survival rates. Crestal
approaches are limited to 5 mm height; short implants have lower survival in poor bone;
osteotome techniques risk membrane perforation with minimal height.
Q2 CRITICALLY EVALUATE IMPLANT TREATMENT PLANNING BASED ON EVIDENCE-BASED
CRITERIA
Which combination of implant surface topography and loading protocol has
demonstrated the most favorable bone-implant contact (BIC) and torque values in
low-density bone?
A. Machined surface, immediate loading, and submerged healing
B. Acid-etched microtopography, delayed loading, and transmucosal healing
C. Plasma-sprayed macrotexture, immediate loading, and submerged healing
D. Anodized nanostructure, early loading, and transmucosal healing CORRECT
RATIONALE: Anodized surfaces (e.g., TiUnite) enhance osseointegration in low-density bone
due to increased surface area and osteogenic potential. Early loading (6-8 weeks) is acceptable
with such surfaces. Machined surfaces show poor BIC; plasma-sprayed surfaces have higher
failure rates; acid-etched without nanostructure is less optimal for poor bone.

,Q3 CRITICALLY EVALUATE IMPLANT TREATMENT PLANNING BASED ON EVIDENCE-BASED
CRITERIA
Which of the following best explains the biomechanical advantage of a
platform-switched implant connection in reducing peri-implant bone loss?
A. Increases the effective prosthetic platform area, distributing occlusal forces more evenly
B. Moves the implant-abutment interface medially, shifting the inflammatory infiltrate away from
the crestal bone CORRECT
C. Enhances the friction fit between components, eliminating microgap bacterial leakage
D. Allows for a larger abutment diameter, improving the emergence profile
RATIONALE: Platform switching positions the abutment of smaller diameter than the implant,
creating a horizontal offset that relocates the microgap and its inflammatory infiltrate away from
the crestal bone, thereby reducing bone resorption. It does not increase platform area; it does not
eliminate microgap; it uses a smaller abutment, not larger.
Q4 CRITICALLY EVALUATE IMPLANT TREATMENT PLANNING BASED ON EVIDENCE-BASED
CRITERIA
A 3D-printed titanium implant with a porous surface structure is being evaluated
for clinical use. Which property most critically influences its osseointegration
potential?
A. Pore size and interconnectivity, which affect cell infiltration and vascularization CORRECT
B. Overall implant shape, which determines primary stability
C. Surface roughness at the nanoscale, which influences protein adsorption
D. The alloy composition, which dictates corrosion resistance
RATIONALE: In porous 3D-printed implants, pore size (typically 300-600 µm) and
interconnectivity are critical for bone ingrowth and vascularization. While surface roughness and
shape are important, the porous architecture is the defining feature for osseointegration in such
implants. Alloy composition affects biocompatibility but not directly osseointegration.

, Q5 CRITICALLY EVALUATE IMPLANT TREATMENT PLANNING BASED ON EVIDENCE-BASED
CRITERIA
In a full-arch implant-supported fixed prosthesis with cantilever extensions, which
modification most effectively reduces the risk of mechanical failure?
A. Increasing the number of abutment screws to four per implant
B. Decreasing the cantilever length to less than one premolar width CORRECT
C. Using a titanium framework instead of cobalt-chromium
D. Placing implants in a straight line to simplify load distribution
RATIONALE: Cantilever length is directly proportional to the bending moment; reducing it to 1
premolar width minimizes stress on implants and prosthesis. Increasing screw number does not
reduce cantilever moment; titanium vs CoCr has similar modulus; straight-line placement can
increase cantilever length due to arch position.
Q6 CRITICALLY EVALUATE IMPLANT TREATMENT PLANNING BASED ON EVIDENCE-BASED
CRITERIA
Which of the following best describes the primary role of the epithelial junction in
maintaining peri-implant mucosal seal?
A. It forms hemidesmosomes with the implant surface, creating a biological barrier CORRECT
B. It secretes mucins that lubricate the transmucosal area
C. It provides a dense collagenous attachment to the implant collar
D. It undergoes keratinization to resist mechanical trauma
RATIONALE: The junctional epithelium attaches to the implant surface via hemidesmosomes and
a basal lamina-like structure, forming a biological seal that prevents bacterial invasion. It does not
secrete mucins; collagen fibers do not attach to the implant surface; peri-implant epithelium is not
keratinized.
