1. Which factor is most critical for achieving predictable osseointegration of a
dental implant?
A. Immediate functional loading in every case
B. Biocompatible implant surface and controlled surgical trauma
C. Use of the longest possible implant
D. Maximum insertion torque regardless of bone condition
Answer: B
Successful osseointegration depends on appropriate implant biocompatibility, preservation
of viable bone, primary stability, and favorable biologic healing. Excessive surgical trauma
or overheating can compromise bone healing .
2. What is the primary purpose of primary implant stability?
A. To eliminate the need for osseointegration
B. To prevent micromotion during initial healing
C. To increase gingival pigmentation
D. To eliminate the need for prosthetic planning
Answer: B
Primary stability is mechanical stability obtained at implant placement. It limits
micromotion and provides a stable environment for subsequent biologic osseointegration .
,3. Excessive micromotion during early healing is most likely to result in:
A. Enhanced bone formation
B. Fibrous encapsulation
C. Increased keratinized tissue
D. Faster osseointegration
Answer: B
Excessive movement at the bone-implant interface can interfere with direct bone
formation and promote formation of fibrous tissue rather than stable osseointegration .
4. Which bone classification generally represents dense cortical bone with minimal
cancellous bone?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: A
Type I bone is characterized by predominantly dense cortical bone. Type II has thick
cortical bone with dense trabecular bone, while Types III and IV contain progressively less
dense trabecular bone .
5. Which bone type generally presents the greatest challenge for achieving
primary stability?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: D
Type IV bone has relatively thin cortical bone and low-density trabecular bone, making
primary stability more difficult to obtain and often requiring modified surgical strategies .
,6. Which cells are primarily responsible for bone resorption?
A. Osteoblasts
B. Osteocytes
C. Osteoclasts
D. Fibroblasts
Answer: C
Osteoclasts are multinucleated cells specialized for bone resorption and remodeling .
7. Which cells are primarily responsible for new bone formation?
A. Osteoclasts
B. Osteoblasts
C. Neutrophils
D. Fibroblasts
Answer: B
Osteoblasts synthesize osteoid and contribute to new bone formation .
8. What is secondary implant stability primarily associated with?
A. Implant thread design only
B. Biologic bone healing and remodeling
C. Insertion torque
D. Abutment material
Answer: B
Secondary stability develops as bone forms and remodels at the implant surface. Primary
mechanical stability and secondary biologic stability work together during healing .
, 9. Resonance frequency analysis is commonly used to evaluate:
A. Pulp vitality
B. Implant stability
C. Gingival color
D. Caries activity
Answer: B
Resonance frequency analysis (RFA) measures implant stability by assessing the stiffness of
the bone-implant interface .
10. Which biological process occurs immediately following surgical injury?
A. Hemostasis
B. Permanent osseointegration
C. Prosthetic loading
D. Crown maturation
Answer: A
Hemostasis is the initial stage of wound healing and involves clot formation and
stabilization .
11. Which factor has the greatest influence on primary implant stability at
placement?
A. Implant color
B. Mechanical engagement with the surrounding bone
C. Crown shade
D. Abutment material
Answer: B
Primary stability is mechanical and depends on factors such as bone density, implant
geometry, and surgical technique .
