ABSTRACT
This study document brings together 50 carefully worded exam questions drawn from ICOI
DIPLOMATE EXAM PRACTICE QUESTIONS AND CORRECT ANSWERS (VERIFIED
ANSWERS) PLUS RATIONALES Q&A INSTANT DOWNLOAD PDF, with the strongest emphasis
placed on Synthesize diagnostic data to formulate risk-stratified implant treatment plans, Apply
current evidence and consensus guidelines to surgical and prosthetic implant decisions and
Recognize and manage peri-implant complications using the latest classification frameworks.
Every item follows the wording style and level of reasoning you meet in the real paper, and each
one is paired with a clear rationale so the correct choice is never a guess. Work through the set at
your own pace, mark the questions that slow you down, then come back to them until the
reasoning feels automatic. Learners who revise this way walk into the exam room recognising the
pattern behind the questions instead of meeting them for the first time. Keep going - steady, honest
practice is what turns a difficult paper into a comfortable pass.

,Q1 SYNTHESIZE DIAGNOSTIC DATA TO FORMULATE RISK-STRATIFIED IMPLANT
TREATMENT PLANS
A partially edentulous posterior mandible exhibits a knife-edge ridge with 3 mm of
buccal-lingual width and a 1.5 mm cortical plate. Which surgical approach best
balances primary stability and long-term crestal bone preservation?
A. Immediate implant placement with simultaneous guided bone regeneration using a resorbable
membrane.
B. Staged lateral ridge augmentation with autogenous block graft, then delayed implant
placement. CORRECT
C. Narrow-diameter implant placement without augmentation, using a platform-switched design.
D. Transalveolar osteotome-mediated ridge expansion with simultaneous implant placement.
RATIONALE: A 3 mm ridge with a 1.5 mm cortical plate cannot reliably support primary stability
or prevent dehiscence; staged block grafting re-establishes adequate bone volume. Immediate
placement or osteotome expansion risks fracture and inadequate bone coverage. Narrow
implants without augmentation do not address the deficient cortical plate and may lead to
long-term bone loss.
Q2 SYNTHESIZE DIAGNOSTIC DATA TO FORMULATE RISK-STRATIFIED IMPLANT
TREATMENT PLANS
Which radiographic modality provides the most accurate assessment of buccal
and lingual cortical plate thickness for pre-surgical implant planning in the
anterior maxilla?
A. Panoramic radiography with cross-sectional occlusal views.
B. Periapical radiography using a paralleling technique.
C. Cone-beam computed tomography (CBCT) with a small field of view. CORRECT
D. Lateral cephalometric radiography combined with panoramic imaging.
RATIONALE: CBCT with a limited field of view delivers high-resolution, three-dimensional data
that accurately quantifies buccal and lingual plate thickness, essential for anterior implant
planning. Panoramic and periapical radiographs provide only two-dimensional views and cannot
assess buccolingual dimensions. Cephalometric imaging is not designed for localized alveolar
assessment.

, Q3 SYNTHESIZE DIAGNOSTIC DATA TO FORMULATE RISK-STRATIFIED IMPLANT
TREATMENT PLANS
According to current evidence, which factor most strongly predicts marginal bone
loss around a two-piece implant after 5 years of function?
A. Implant surface roughness (Sa value) exceeding 1.5 µm.
B. Distance from the implant-abutment microgap to the first bone-to-implant contact.
CORRECT
C. Use of a titanium base abutment versus a zirconia abutment.
D. Insertion torque exceeding 45 Ncm at placement.
RATIONALE: The vertical distance from the microgap to the first bone-to-implant contact is a
critical determinant of crestal bone remodeling; a shorter distance is associated with less bone
loss. Surface roughness, abutment material, and high insertion torque do not consistently predict
long-term marginal bone loss in contemporary studies.
Q4 SYNTHESIZE DIAGNOSTIC DATA TO FORMULATE RISK-STRATIFIED IMPLANT
TREATMENT PLANS
A patient with a history of treated periodontitis and residual probing depths of 5-6
mm requests implant therapy. Which peri-implant preventive protocol is most
strongly supported by current evidence?
A. Implant placement without additional periodontal therapy, relying on implant surface
characteristics to prevent disease.
B. Completion of active periodontal therapy and enrollment in a supportive periodontal care
program before implant placement. CORRECT
C. Prophylactic systemic antibiotics for 7 days before and after implant surgery.
D. Use of laser-assisted peri-implant debridement every 3 months post-placement.
RATIONALE: Evidence consistently shows that untreated periodontitis increases peri-implantitis
risk; completing active therapy and enrolling in supportive care improves implant survival.
Prophylactic antibiotics and laser debridement are not substitutes for definitive periodontal
treatment. Relying solely on implant surface properties ignores the infectious etiology.
