Summary
The Pinhole Surgical Technique (PST) offers a minimally invasive approach for root coverage, avoiding secondary donor sites. This study shows PST is a predictable and effective method for treating gingival recession with high patient satisfaction.
Area of Science:
- Periodontology
- Minimally Invasive Surgery
- Regenerative Dentistry
Background:
- Free connective tissue grafts are standard for root coverage but involve donor site morbidity.
- Interest is growing in alternative, less invasive techniques for treating gingival recession.
Purpose of the Study:
- To evaluate the feasibility and outcomes of the novel Pinhole Surgical Technique (PST) for root coverage.
- To assess PST's predictability, effectiveness, and patient-based results.
Main Methods:
- A retrospective study of 43 patients with 121 recession sites treated with PST.
- Analysis of root coverage, defect reduction, procedure duration, patient satisfaction, and complications.
- Graft materials included bioresorbable membrane or acellular dermal matrix.
Main Results:
- Complete root coverage achieved in 81.2% of Class I/II sites and 69.4% of all sites.
- Mean defect reduction was 94.0% for Class I/II and 88.4% for all sites.
- High patient esthetic satisfaction (95.1%) achieved quickly with minimal complications.
Conclusions:
- PST is a predictable and effective minimally invasive surgical option for root coverage.
- The technique eliminates the need for secondary surgical sites and extensive dissection.
- PST offers a time- and cost-effective solution with excellent patient-reported outcomes.
