Summary
The socket-shield technique may reduce bone loss after tooth extraction, but clinical evidence is limited. More high-quality studies are needed to confirm its long-term effectiveness for dental implants.
Area of Science:
- Dental Implantology
- Periodontology
- Oral Surgery
Background:
- Dental implants are standard for missing teeth.
- Buccal bone resorption after extraction and implant placement can cause cosmetic issues.
- Retaining the natural tooth root minimizes bundle bone resorption.
Purpose of the Study:
- To review existing literature on the socket-shield technique.
- To evaluate the current evidence for root retention in preserving bone around dental implants.
Main Methods:
- A systematic PubMed search was performed.
- Identified publications were screened based on inclusion/exclusion criteria.
- Literature review focused on the socket-shield technique by Hurzeler et al.
Main Results:
- The initial search yielded 229 results.
- 12 studies met the criteria after abstract screening and full-text review.
- The literature primarily consists of case reports and limited retrospective studies.
Conclusions:
- The socket-shield technique shows potential for reducing bone grafting needs in the aesthetic zone.
- Clinical data supporting the technique's efficacy and long-term stability is currently very limited.
- A lack of well-designed prospective randomized controlled trials hinders definitive conclusions.
