Summary
This study shows that a coronally positioned gingival autograft effectively treats large localized gingival recessions, achieving significant root coverage and increasing attached gingiva. The surgical technique proved highly predictable over a 6-month period.
Area of Science:
- Periodontology
- Oral Surgery
Background:
- Gingival recession affects a significant portion of the population.
- Large localized gingival recessions pose a challenge for periodontal regeneration.
- Root coverage and gain in attached gingiva are key treatment goals.
Purpose of the Study:
- To evaluate the efficacy of coronally positioned gingival autografts for treating large localized gingival recessions.
- To assess root coverage, sulcus depth changes, and gain in attached gingiva.
- To determine the predictability of the surgical technique.
Main Methods:
- 16 cases of localized gingival recession (3.5-10 mm) were treated.
- Coronally positioned gingival autografts were utilized.
- Mechanical (root planing) and chemical (citric acid) root surface treatments were performed.
Main Results:
- 72.17% average root coverage was achieved.
- A gain of 3.0 +/- 1.4 mm in attached gingiva was observed.
- No significant change in sulcus depth was noted.
Conclusions:
- Coronally positioned gingival autografts are highly predictable for treating large localized gingival recessions.
- The technique effectively increases attached gingiva in previously deficient areas.
- A positive correlation exists between pre-treatment bone level and recession extent.
