Recently, we proposed a minimally invasive procedure, the single\u2010flap approach (SFA), specifically indicated when the defect extension is prevalent on the buccal or oral side. The basic principle of the SFA is the elevation of a flap to access the defect only on one side (buccal or oral), leaving the opposite side intact. The present case series reports preliminary data on the clinical effectiveness of SFA with buccal access in conjunction with a collagen membrane and a hydroxyapatite (HA)\u2010based biomaterial in the reconstructive treatment of deep periodontal intraosseous defects.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    Ten intraosseous defects in 10 patients were accessed with a buccal SFA and treated with a collagen membrane and an HA\u2010based graft biomaterial. The follow\u2010up period following the regenerative procedure ranged from 6 to 14 months (mean: 10.0 \u00b1 3.0 months).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Clinical attachment level (CAL) decreased from 11.2 \u00b1 2.6 mm presurgery to 6.4 \u00b1 1.9 mm post\u2010surgery. Probing depth was 9.0 \u00b1 2.8 mm before surgery and 3.8 \u00b1 1.5 mm post\u2010surgery. Gingival recession increased from 2.2 \u00b1 1.9 mm presurgery to 2.6 \u00b1 1.3 mm post\u2010surgery.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Challenging intraosseous defects, surgically accessed with a buccal SFA and treated with a combined graft\/guided tissue regeneration technique, may heal with a substantial CAL gain.
