,Q1 CRITICALLY EVALUATE IMPLANT TREATMENT OPTIONS BASED ON EVIDENCE-BASED
CRITERIA
In a full-arch fixed implant-supported prosthesis with a cantilever, which
biomechanical parameter most critically influences the bending moment at the
implant-abutment interface under lateral occlusal forces?
A. The number of implants supporting the prosthesis
B. The distance from the distal implant to the cantilever tip CORRECT
C. The occlusal table width in the premolar region
D. The implant-abutment connection type (internal vs. external)
RATIONALE: The bending moment is the product of force and the lever arm; the cantilever length
directly increases the moment arm, magnifying stress at the implant-abutment interface. While
implant number and connection type influence load distribution, the cantilever length is the
primary geometric factor determining the moment. Occlusal table width affects force magnitude
but not the lever arm as directly.
Q2 CRITICALLY EVALUATE IMPLANT TREATMENT OPTIONS BASED ON EVIDENCE-BASED
CRITERIA
A completely edentulous patient presents with severe ridge resorption and a high
smile line. Which prosthetic option provides the most predictable esthetic and
functional outcome while minimizing the need for bone grafting?
A. Implant-supported overdenture with bar attachment
B. Four-implant fixed prosthesis with pink gingival porcelain
C. Zygomatic implant-supported fixed prosthesis CORRECT
D. Removable complete denture with tissue conditioning
RATIONALE: Zygomatic implants engage the zygomatic bone, often eliminating the need for
grafting in severely resorbed maxillae, and can support a fixed prosthesis that addresses high
smile line esthetics with minimal soft tissue show. Overdentures may lack stability and fixed
prostheses on standard implants require adequate bone. Removable dentures do not provide the
same functional stability.

,Q3 CRITICALLY EVALUATE IMPLANT TREATMENT OPTIONS BASED ON EVIDENCE-BASED
CRITERIA
For a single posterior implant crown, which occlusal scheme is most effective in
reducing the risk of screw loosening and prosthetic failure?
A. Group function with no canine guidance
B. Mutually protected occlusion with anterior guidance CORRECT
C. Bilateral balanced occlusion
D. Lingualized occlusion
RATIONALE: Mutually protected occlusion ensures that anterior teeth disclude posterior implants
during excursive movements, reducing lateral forces on the implant crown. Group function and
bilateral balanced occlusion can create non-axial forces. Lingualized occlusion may be used in
dentures but is less ideal for implant crowns.
Q4 CRITICALLY EVALUATE IMPLANT TREATMENT OPTIONS BASED ON EVIDENCE-BASED
CRITERIA
Which of the following best describes the primary failure mode of a
cement-retained implant crown when the abutment screw is torqued to the
manufacturer's recommended value?
A. Screw fracture due to excessive preload
B. Cement washout leading to peri-implantitis
C. Abutment loosening from inadequate seating CORRECT
D. Porcelain chipping from occlusal overload
RATIONALE: In cement-retained crowns, the abutment screw is the critical connection; if the
crown is not fully seated, the abutment may not be fully engaged, leading to screw loosening
despite proper torque. Screw fracture is rare with correct torque. Cement washout can occur but
is not the primary failure mode. Porcelain chipping is a separate complication.

, Q5 CRITICALLY EVALUATE IMPLANT TREATMENT OPTIONS BASED ON EVIDENCE-BASED
CRITERIA
A 55-year-old patient (not age-focused) presents with a failing implant-supported
fixed dental prosthesis exhibiting recurrent screw loosening. Radiographs show
no bone loss, but the prosthesis has a distal cantilever. Which modification is
most likely to resolve the issue?
A. Increase the number of abutment screws
B. Use a torque wrench with higher torque
C. Reduce the cantilever length and use a screw-retained design CORRECT
D. Apply a threadlocker to the screws
RATIONALE: Recurrent screw loosening in a cantilevered prosthesis is often due to excessive
cantilever forces. Reducing the cantilever length decreases the moment arm, and a
screw-retained design provides better access for retorque and avoids cement issues. Adding
screws or increasing torque does not address the biomechanical overload. Threadlockers are not
recommended for implant screws.
Q6 CRITICALLY EVALUATE IMPLANT TREATMENT OPTIONS BASED ON EVIDENCE-BASED
CRITERIA
In the context of implant prosthodontics, what is the primary purpose of using a
verification jig (index) during the fabrication of a multi-unit implant prosthesis?
A. To ensure accurate transfer of implant positions from the mouth to the master cast
CORRECT
B. To verify the occlusion before final prosthesis delivery
C. To check the fit of the metal framework before veneering
D. To assess the soft tissue contour around the implants
RATIONALE: A verification jig is used to confirm that the master cast accurately reflects the
intraoral implant positions, preventing framework misfit. It is not used for occlusion or soft tissue
assessment. Framework fit is verified intraorally, not with a jig.
