On the day of implant surgery, what must be achieved for predictable osseointegration?
Show answer and explanation
Correct answer: A. Primary (mechanical) stability
- A. Correct. Primary stability—mechanical engagement of the implant in bone at placement—is required to minimize micromotion during healing.
- B. Secondary stability develops later as bone remodels around the implant.
- C. Immediate full occlusal loading is generally avoided to protect healing.
- D. Bone remodeling occurs over months, not on the surgery day.
