Ridge preservation (RP) techniques effectively reduce alveolar ridge contraction after tooth extraction, though no single graft material is superior. Further long-term data is needed for dental implant success.
Area of Science:
- Dentistry
- Oral Surgery
- Periodontology
Background:
- Alveolar ridge resorption after tooth extraction can compromise future dental implant placement.
- Various ridge preservation (RP) techniques aim to mitigate this bone loss.
- Promising results have been reported for RP in different clinical scenarios.
Purpose of the Study:
- To evaluate the role and reliability of ridge preservation (RP) in the anterior esthetic zone.
- To assess the effectiveness of RP techniques in preserving alveolar bone height and width.
- To inform decisions regarding implant placement following tooth extraction.
Main Methods:
- Systematic literature search of MEDLINE and PubMed databases.
- Inclusion of 11 human studies (RCTs, CCTs, prospective/retrospective) with at least 5 subjects and 3-month follow-up.
- Exclusion of studies with primary closure or non-single-rooted/bicuspid sites.
Main Results:
- All included studies demonstrated reduced ridge contraction in grafted sites compared to non-grafted sites.
- No specific graft material showed superiority across the evaluated studies.
- Heterogeneity in techniques, materials, and healing times limited direct comparison.
Conclusions:
- Ridge preservation is effective in minimizing alveolar ridge reduction post-extraction.
- Grafting materials appear beneficial, but material-specific advantages are not evident from this review.
- Long-term outcome data for dental implants placed in RP sites are still required.
