Socket Preservation UR4, UR5 Case Study

1. Flap raised on buccal aspect, defect clearly visible.
2. UR4 and UR5 removed whole with forceps and luxating elevator. Sockets thoroughly degranulated.
3. 1 x 0.5cc and 1 x 1.0cc of EthOss® placed into sockets. Dry gauze held over material for 3 minutes until it starts to harden.
4. Sinoss collagen fleece sutured over each extraction socket with 3-0 vicryl absorbable sutures.
5. Site uncovered 10 weeks later, adequate new bone formation to allow implant placement.
6. 2 x Astra Tech EV implants placed with healing abutments.
7. Flap closed over with Vicryl Rapide 4-0 sutures (resorbable).
8. Healed site at 10 weeks.
9. ISQ measured with PenguinRFA meter: UR4 implant = 81 and UR5 implant = 82. High stability showing good osseointegration.
10. 4 weeks later – definitive implant crowns with patient-specific “Atlantis” abutments placed.
11. Final result.

Radiograph:

1. Initial situation.
2. Following extraction and simultaneous grafting with EthOss®
3. 10 weeks later, osteotomy sites prepared to 6mm depth and check with depth gauge.
4. Impants placed.
5. Final result, implants loaded 14 weeks following placement.
