Summary
The maxillary tuberosity gingival cuff is a simpler, predictable donor site for root coverage procedures, offering successful tissue integration and long-term stability. This method improves gingival biotype and color match.
Area of Science:
- Periodontology
- Regenerative Dentistry
- Oral Surgery
Background:
- The palatal area is the traditional donor site for connective tissue grafts in root coverage procedures.
- This study investigates the maxillary tuberosity gingival cuff as an alternative donor site for root coverage.
Observation:
- Two cases of gingival recession treated with connective tissue grafts from the maxillary tuberosity using pouch and semilunar techniques.
- Patients were followed for 31 and 35 months post-surgery.
- Surgical intervention included gingivectomy at 3 months to manage graft bulk.
Findings:
- Complete root coverage was achieved in both cases with uneventful healing.
- Histological analysis showed good graft adaptation and epithelialization.
- Gingival biotype shifted from thin to thick, with successful color matching and stable probing depths.
Implications:
- The maxillary tuberosity offers a less invasive and highly predictable alternative donor site for root coverage.
- This technique simplifies root coverage procedures compared to palatal grafts.
- The method demonstrates long-term stability and favorable aesthetic outcomes.
