After root completion implant collagen matrix formation — how long does it take for the initial collagen matrix to be deposited following implant placement?

Correct answer: B. 4-6 weeks

• A. 1-3 weeks is the inflammatory and early proliferative phase — collagen matrix development peaks later.
• B. Correct. Following implant placement, wound healing progresses through stages: hemostasis (minutes-hours) → inflammation (hours-days) → proliferation (days-weeks) → maturation/remodeling. The initial collagen matrix deposition occurs during the proliferative phase, approximately 4-6 weeks post-placement. Osseointegration is typically evaluated at 3-6 months.
• C. 8-12 weeks is the late proliferative/early remodeling phase.
• D. 6 months represents mature osseointegration — not initial collagen matrix.
