After extraction: preserve, graft, or place
Choosing between spontaneous healing, alveolar ridge preservation, and immediate implant placement based on socket wall integrity and the future implant plan. Unassisted post-extraction sites lose roughly 29–63% of ridge width and 11–22% of height within 6 months.
Use: Post-extraction site planning
Gatekeeper: Buccal wall status
Framework: Osteology / EAO consensus
01 — Site Classification
Reading the extraction socket
Bony wall integrity — particularly the thin buccal plate — is the dominant predictor of dimensional change and the key input to the preservation decision.
Socket type
Intact 4-wall socket
- All bony walls intact, including buccal plate
- Thin buccal wall still resorbs as bundle bone is lost
- Most favorable for any approach
- Candidate for grafting or immediate placement
Socket type
Damaged / buccal-wall loss
- Dehiscence or fenestration of buccal plate
- Greater, less predictable resorption expected
- Favors preservation; often staged augmentation
- Immediate placement higher-risk — avoid unless skilled
Socket type
Molar / large socket
- Wide, multi-rooted defect with inter-radicular septum
- Large void; primary closure difficult
- Grafting helps maintain volume for later placement
- Consider socket-shield / sealing membrane techniques
02 — Decision Pathway
Interactive preservation selector
Combine socket-wall status with the future implant plan. Atraumatic extraction and preservation of the buccal plate underpin every pathway.
Tap the scenario that matches the socket and the restorative plan.
Step 1 — Socket walls + future implant plan?
NO GRAFT
Intact walls, no implant / late placement
Site not planned for an implant, or restoration deferred indefinitely.
PRESERVE
Damaged wall or implant planned later
Volume must be maintained for a delayed implant in 4–6 months.
PLACE NOW
Intact walls + ideal anatomy for immediate
Adequate apical/palatal bone, good primary stability achievable.

03 — Quick Reference
Technique, biomaterial, and timing to placement
Material and membrane choices are largely operator-preference; grafted sites generally require ~4–6 months of maturation before implant placement.
| Pathway | Technique / biomaterial | Timing to placement |
|---|
| Spontaneous healing | Atraumatic extraction; no graft; +/- collagen plug for clot stability | ~3–6 mo (expect ridge collapse) |
| Socket / ridge preservation | Particulate graft (DBBM, allograft, alloplast) + membrane / collagen matrix; sealing or primary closure | ~4–6 mo |
| Immediate implant | Place into intact socket; gap-graft buccal jumping distance; consider custom healing abutment | Same visit — see placement-timing module |
| Damaged buccal wall | Staged GBR with graft + barrier; defer placement | ~6+ mo, re-evaluate |
