Summary
Socket shield technique aids tissue volume maintenance. Replanting a mistakenly extracted root fragment unexpectedly led to successful bone regeneration and uneventful implant healing over five years.
Area of Science:
- Dentistry
- Oral Surgery
- Implantology
Background:
- Socket shield technique aims to preserve alveolar bone and soft tissue volume during tooth extraction and immediate implant placement.
- This case involves an unusual complication during socket shield surgery: the accidental extraction of a root fragment.
Observation:
- A buccal root fragment was mistakenly extracted during socket shield surgery.
- The extracted fragment was shaped extraorally and replanted into the socket, protruding above the alveolar crest.
- An 88-year-old patient received an immediate loading implant concurrently with the root fragment replantation.
Findings:
- A 5-year follow-up revealed uneventful healing of the dental implant.
- Postoperative cone-beam computed tomography (CBCT) at 48 months showed bone regeneration over the replanted root fragment portion that extended beyond the crest.
- The replanted root fragment acted as a scaffold, promoting new bone formation.
Implications:
- This case suggests that replanting a portion of a tooth root, even if mistakenly extracted, can lead to successful bone regeneration and implant integration.
- The technique allows for extraoral shaping of the fragment, potentially simplifying its adaptation.
- This approach may offer a viable option for managing bone defects in the buccal socket, utilizing sound portions of the root.
