Healing with Immediate Implants
David Wilson, DDS
Wednesday, September 24, 14
Protocols for Implant Placement
Type I: Implant placement immediately following tooth extraction and as part of the same surgical procedure
Type 2: Complete soft tissue coverage (typically 4-8wks)
Type 3: Substantial clinical and/or radiographic bone fill of the socket (typically 12-16 weeks)
Type 4: Healed site (typically more than 16 weeks)

Immediate Loading: Contraindications

Extraction socket repair 1. Hemorrhage!
2.Clot formation!
3. Inflammatory reaction-> recruitment of cells!
4. 48-72 hrs granulation tissue starts to replace clot!
5. 4 days- epithelium proliferates, immature CT!
6. 7 days- granulation tissue completely replaces clot, osteoid evident at the base of socket!
7. 2-3 weeks (3 to 4 wks after ext)- CT replaces granulation tissue, osteoid mineralizes coronally !
8. 6 weeks- epithelialization complete, bone fills more than 2/3 of socket!
