The goal of this study was to retrospectively evaluate the clinical outcomes of the Flapless technique in treatment of severe periodontitis after three year. A non-aggressive technique for periodontal bone grafts was developed and tested on 19 subjects. The technique involved scaling and root planing, and the insertion of single grains of bone mineral through the crevicular space into the pocket until it’s completely fi lled. All patients received monthly periodontal maintenance therapy for six months and then every three months for 2.5 years. Clinical parameters were assessed at baseline and after three years; these included probing depth (PD), clinical attachment level (CAL), and gingival recession (GR); the presence of bone defects was determined radiographically. The signifi cance of the data was confi rmed statistically. There was signifi cant reduction in PD (4.9mm, P<0.005) and CAL gain (3.73mm, P<0.005), and a slight increase of in GR (1.16mm, P<0.005). After six months, it led to radiographic resolution of osseous lesions. Flapless Technique resulted in clinically relevant amounts of CAL gains, shallow pockets, minimal gingival recession, and radiographic osseous defect fi ll. This minimally invasive approach offers an effi cient, safe and well-tolerated alternative for the longterm treatment of severe periodontitis in interproximal pockets of single-rooted teeth.
