Sample Dental Implants Practice Questions
Try these questions from our free Dental Implants practice tests. The correct answer and an explanation follow each question.
A screw loosening complication with an implant crown is most commonly caused by:
- A. Insufficient torque or occlusal overload generating bending moments
- B. Using titanium abutment screws
- C. Poor oral hygiene around the implant
- D. Implant placed too deep in bone
Answer: A. Insufficient torque or occlusal overload generating bending moments
Inadequate tightening torque or excessive occlusal forces — especially lateral interferences — are the most common causes of abutment or retaining screw loosening.
Peri-implant mucositis is best described as:
- A. Irreversible bone loss around an implant
- B. Reversible inflammation limited to the soft tissue around an implant without bone loss
- C. Complete implant failure
- D. Infection of the surgical site only
Answer: B. Reversible inflammation limited to the soft tissue around an implant without bone loss
Peri-implant mucositis is the implant equivalent of gingivitis — reversible soft tissue inflammation without bone loss that responds to improved oral hygiene.
Which flap design in implant surgery minimizes damage to the blood supply and preserves interdental papillae?
- A. Full-thickness trapezoidal flap
- B. Papilla-sparing (papilla preservation) incision
- C. Crestal split-thickness flap
- D. Envelope flap without vertical releasing incisions
Answer: B. Papilla-sparing (papilla preservation) incision
Papilla-sparing incision designs avoid cutting through the papillae, preserving their blood supply and reducing esthetic complications.
Which type of GBR membrane requires a planned second surgical procedure for removal?
- A. Collagen membrane
- B. Polylactic acid membrane
- C. Polyglycolic acid membrane
- D. Expanded polytetrafluoroethylene (e-PTFE) membrane
Answer: D. Expanded polytetrafluoroethylene (e-PTFE) membrane
Non-resorbable e-PTFE (Gore-Tex) membranes provide superior space maintenance but must be surgically retrieved in a second procedure; collagen, polylactic acid, and polyglycolic acid membranes are all bioresorbable and degrade without additional surgery.
