Summary
The socket-shield technique (SST) successfully preserved bone and soft tissue in a lower molar extraction site, demonstrating its potential for posterior dental implants. This technique minimizes post-extraction ridge resorption, enhancing implant outcomes.
Area of Science:
- Dental Implantology
- Periodontology
- Oral Surgery
Background:
- The socket-shield technique (SST) aims to prevent post-extraction ridge resorption by preserving root segments.
- While used in anterior sites, SST's efficacy in posterior molar sites is largely unexplored.
- This case report investigates SST application in a mandibular molar extraction site.
Observation:
- A 34-year-old patient received immediate implant placement using SST for a non-restorable mandibular first molar.
- Cone-beam CT scans and clinical assessments were performed up to 12 months post-procedure.
- The procedure involved retaining buccal root segments as shields during implant placement.
Findings:
- The socket-shield technique (SST) procedure was completed without complications.
- Minimal horizontal bone loss of approximately 0.2 mm at 4 months and 0.1 mm by 12 months was observed.
- Stable peri-implant soft tissue contours and successful osseointegration with high stability were achieved.
Implications:
- SST effectively preserved alveolar bone and soft tissue in a posterior molar site, mitigating typical post-extraction collapse.
- The findings suggest SST is a viable approach for tissue preservation in posterior implantology.
- Further long-term studies are required to confirm sustained outcomes and predictability of the technique.
