,Q1 ANALYZE MULTIFACTORIAL ETIOLOGIES OF IMPLANT COMPLICATIONS AND
FORMULATE EVIDENCE-BASED MANAGEMENT STRATEGIES
Which of the following best explains the higher susceptibility of peri-implant
mucosa to inflammatory destruction compared to natural gingiva?
A. Lack of Sharpey's fiber insertion into implant surface CORRECT
B. Reduced vascular supply in the peri-implant soft tissue
C. Absence of keratinized mucosa around implants
D. Increased expression of RANKL in peri-implant crevicular fluid
RATIONALE: The natural gingiva has connective tissue fibers (Sharpey's) inserting into
cementum, creating a robust seal. Around implants, collagen fibers run parallel to the surface,
lacking true insertion, making the biological width more vulnerable to bacterial invasion. Reduced
vascularity (B) is not a primary feature; keratinized mucosa (C) is not universally required;
RANKL expression (D) is a consequence, not the primary structural reason.
Q2 ANALYZE MULTIFACTORIAL ETIOLOGIES OF IMPLANT COMPLICATIONS AND
FORMULATE EVIDENCE-BASED MANAGEMENT STRATEGIES
A patient presents with a fractured implant abutment screw. The screw fragment is
retained in the implant body. Which sequence of steps is most appropriate for
retrieval?
A. Use an ultrasonic scaler to loosen the fragment, then reverse with a hemostat
B. Create a reverse-threaded channel with a bur, then use a screw extractor CORRECT
C. Apply a high-speed diamond bur to section the fragment and remove piecemeal
D. Leave the fragment and place a new abutment with a larger diameter screw
RATIONALE: The standard protocol for retrieving a fractured abutment screw involves creating a
counterclockwise channel using a specialized bur or kit, followed by a screw extractor. This
preserves the internal threads of the implant. Ultrasonic scalers (A) are ineffective for metal
fragments; sectioning (C) risks damaging implant threads; leaving the fragment (D) compromises
prosthetic fit and may lead to failure.

,Q3 ANALYZE MULTIFACTORIAL ETIOLOGIES OF IMPLANT COMPLICATIONS AND
FORMULATE EVIDENCE-BASED MANAGEMENT STRATEGIES
Which of the following factors most strongly predicts the progression of
peri-implantitis after initial non-surgical therapy?
A. Presence of keratinized mucosa width less than 2 mm
B. History of periodontitis with incomplete periodontal treatment CORRECT
C. Implant surface roughness (SLA vs. machined)
D. Smoking status of more than 10 cigarettes per day
RATIONALE: Evidence shows that a history of periodontitis, especially with residual pockets, is a
strong predictor of peri-implantitis progression and recurrence after non-surgical therapy. While
smoking (D) and poor keratinized mucosa (A) are risk factors, they are not as strongly associated
with progression after therapy as untreated periodontal disease. Implant surface roughness (C)
influences initial biofilm accumulation but is less predictive of progression post-treatment.
Q4 ANALYZE MULTIFACTORIAL ETIOLOGIES OF IMPLANT COMPLICATIONS AND
FORMULATE EVIDENCE-BASED MANAGEMENT STRATEGIES
In the management of a failing implant with severe bone loss and mobility, which
of the following explantation techniques minimizes trauma to the remaining
alveolar ridge?
A. High-speed bur sectioning of the implant along its long axis
B. Reverse torque with a specialized implant removal tool
C. Use of an ultrasonic surgical device with diamond-coated tips CORRECT
D. Piezoelectric surgery with a thin diamond disc around the implant
RATIONALE: Ultrasonic surgical devices (e.g., Piezosurgery) with diamond-coated tips allow
precise cutting of the bone-implant interface while preserving vital structures and soft tissue,
making them ideal for atraumatic explantation. Reverse torque (B) is only effective for
osseointegrated implants without severe bone loss; high-speed bur sectioning (A) risks
overheating and excessive bone removal; piezoelectric disc (D) is less effective for implant
removal.

, Q5 ANALYZE MULTIFACTORIAL ETIOLOGIES OF IMPLANT COMPLICATIONS AND
FORMULATE EVIDENCE-BASED MANAGEMENT STRATEGIES
Which of the following is the most critical factor in preventing mechanical
complications in implant-supported fixed dental prostheses?
A. Use of gold-alloy abutment screws torqued to 35 Ncm
B. Designing a passive fit of the framework CORRECT
C. Selection of a titanium abutment over zirconia
D. Application of a occlusal splint for bruxism
RATIONALE: Passive fit is essential to avoid stress concentrations that lead to screw loosening,
fracture, and bone loss. A passive framework minimizes strain on the implant-abutment complex.
While torque (A) and material selection (C) are important, they cannot compensate for a misfit.
Occlusal splints (D) help manage bruxism but do not address framework fit.
Q6 ANALYZE MULTIFACTORIAL ETIOLOGIES OF IMPLANT COMPLICATIONS AND
FORMULATE EVIDENCE-BASED MANAGEMENT STRATEGIES
A patient with an implant-supported single crown exhibits a grayish discoloration
of the peri-implant mucosa. Which of the following is the most likely cause and
appropriate solution?
A. Thin mucosa and metal abutment; switch to zirconia abutment CORRECT
B. Gingival inflammation; improve oral hygiene
C. Implant malposition; surgical repositioning
D. Cement residue; remove and re-cement
RATIONALE: Grayish discoloration is typically due to the metallic abutment showing through thin
peri-implant mucosa. Replacing the metal abutment with a tooth-colored zirconia abutment is the
standard solution. Inflammation (B) causes redness, not gray; malposition (C) causes aesthetic
issues but not specifically gray hue; cement residue (D) causes inflammation and peri-implantitis,
not discoloration.
