Q

A

week 1
- WBC remove bacteria
- bone fragment breakdown
- fibroplasia
- fibroblast and capillary growth
- epithelium migrate down socket wall
- osteoclasts accumulate

week 2
- granulation tissue fills socket
- osteoid depositing along alveolar bone

week 3
- cortical bone resorbs from crest and wall
- new trabecular bone
- cortical bone fully resorbed
- epithelium moves to crest
