CIT Treatment Protocols & Procedures 2 — Questions and Answers
Question 1: Which flap design is most commonly used for implant placement in areas with adequate keratinized tissue?
- Full-thickness mucoperiosteal flap (Correct answer)
- Split-thickness flap
- Envelope flap without vertical releasing incisions
- Pedicle flap
Correct answer: Full-thickness mucoperiosteal flap
A full-thickness mucoperiosteal flap provides optimal access and visualization while preserving the periosteum for bone healing.
Question 2: What is the recommended minimum healing time before loading a standard implant placed in a healed site with good primary stability?
- 2–4 weeks
- 4–6 weeks
- 8–12 weeks (Correct answer)
- 6 months
Correct answer: 8–12 weeks
Most protocols recommend 8–12 weeks for osseointegration in healed sites before conventional loading.
Question 3: During implant osteotomy preparation, what is the primary purpose of using sequential drills of increasing diameter?
- To remove necrotic bone
- To gradually compress and shape bone while minimizing heat (Correct answer)
- To irrigate the site with saline
- To assess bone density at each level
Correct answer: To gradually compress and shape bone while minimizing heat
Sequential drilling gradually enlarges the osteotomy while controlling friction heat, protecting bone vitality.
Question 4: An implant is placed 1 mm below the crestal bone level. This placement is referred to as:
- Supracrestal placement
- Equicrestal placement
- Subcrestal placement (Correct answer)
- Transmandibular placement
Correct answer: Subcrestal placement
Subcrestal placement positions the implant platform below the alveolar crest, often used with certain implant systems to enhance soft tissue contour.
Question 5: Which of the following best describes the purpose of a healing abutment (cover screw vs. healing cap) after implant placement?
- A healing abutment shapes the gingival emergence profile during soft tissue healing (Correct answer)
- A cover screw maintains gingival contour while the implant heals subgingivally
- A healing abutment is used only for immediate loading protocols
- A cover screw is always preferred over a healing abutment
Correct answer: A healing abutment shapes the gingival emergence profile during soft tissue healing
A healing abutment (transmucosal) shapes the peri-implant soft tissue emergence profile during the healing phase.
Question 6: When performing socket seal surgery, the primary goal is to:
- Accelerate bone regeneration with a membrane
- Close the extraction socket with soft tissue to retain a graft (Correct answer)
- Immediately place an implant into the fresh socket
- Remove all granulation tissue before closure
Correct answer: Close the extraction socket with soft tissue to retain a graft
Socket seal surgery uses a connective tissue or collagen plug to close the entrance of the grafted extraction socket, protecting the graft.
Question 7: What is the significance of achieving at least 35 Ncm of insertion torque during implant placement?
- It confirms the implant is at the correct depth
- It indicates sufficient primary stability for potential immediate provisionalization (Correct answer)
- It verifies correct angulation of the implant
- It ensures the implant platform is equicrestal
Correct answer: It indicates sufficient primary stability for potential immediate provisionalization
Insertion torque ≥35 Ncm is commonly used as a threshold for acceptable primary stability when considering immediate or early loading protocols.
