Dental Advanced Topics 3 — Questions and Answers
Question 1: Which type of bone graft uses material harvested from the same patient?
- Autograft (Correct answer)
- Allograft
- Xenograft
- Alloplast
Correct answer: Autograft
An autograft is taken from the patient's own body and is considered the gold standard for grafting.
Question 2: In implant dentistry, what does 'osseointegration' refer to?
- Direct structural contact between bone and implant surface (Correct answer)
- Soft tissue attachment to the crown
- Bonding of cement to enamel
- Fusion of two adjacent teeth
Correct answer: Direct structural contact between bone and implant surface
Osseointegration is the direct functional and structural connection between living bone and the implant surface.
Question 3: Which condition is characterized by inflammation and bone loss around an osseointegrated implant?
- Peri-implantitis (Correct answer)
- Mucositis without bone loss
- Pericoronitis
- Gingivitis
Correct answer: Peri-implantitis
Peri-implantitis involves both soft tissue inflammation and progressive bone loss around an implant.
Question 4: What is the main advantage of cone beam computed tomography (CBCT) over conventional radiographs in advanced dentistry?
- Three-dimensional imaging of structures (Correct answer)
- Lower cost than bitewings
- No radiation exposure
- Faster than a panoramic film only
Correct answer: Three-dimensional imaging of structures
CBCT provides 3D imaging, allowing accurate assessment of bone, nerves, and anatomy for planning.
Question 5: Which suture material is non-resorbable and commonly used in periodontal surgery?
- Silk or ePTFE (Correct answer)
- Plain gut
- Chromic gut
- Polyglycolic acid
Correct answer: Silk or ePTFE
Silk and ePTFE are non-resorbable sutures requiring removal, unlike gut or polyglycolic acid.
Question 6: What is the recommended waiting period before loading a conventional implant in good-quality bone (delayed loading)?
- About 3 to 6 months (Correct answer)
- 24 hours
- 1 week
- 2 years
Correct answer: About 3 to 6 months
Conventional delayed loading typically allows 3 to 6 months for osseointegration before restoration.
Question 7: Which advanced restorative technique uses a ceramic onlay milled chairside in a single visit?
- CAD/CAM (e.g., CEREC) (Correct answer)
- Conventional cast gold
- Pin-retained amalgam
- Stainless steel crown
Correct answer: CAD/CAM (e.g., CEREC)
CAD/CAM systems like CEREC design and mill ceramic restorations chairside in one appointment.
