Supra-alveolar attachment gain in the treatment of combined intra-suprabony periodontal defects by non-incised papillae surgical approach.

AIM

To assess the effectiveness of non-incised papillae surgical approach (NIPSA) in periodontal reconstructive surgery of combined intra-suprabony defects.

MATERIALS AND METHODS

Patients with deep periodontal defects treated with NIPSA (n = 20) were analysed. Defects were treated with enamel matrix derivative plus xenograft. Clinical outcomes were assessed before surgery and at 12 months. Wound closure was assessed one week post-surgery. Supra-alveolar attachment gain (SUPRA-AG) was recorded at 12 months post-surgery.

RESULTS

Non-incised papillae surgical approach showed significant improvements in clinical attachment gain (5.9 ± 2.38 mm; p < 0.001), recession reduction (0.25 ± 0.44; p < 0.05) and tip of the papillae coronal displacement (0.4 ± 0.5; p < 0.05). It also showed complete wound closure of the apical mucosal incision in the 85% of the cases, with no interproximal tissue necrosis. SUPRA-AG (1.9 ± 1.74) showed a positive tendency, associated with complete intrabony defect resolution.

CONCLUSIONS

Non-incised papillae surgical approach promoted primary intention healing, wound stability and space provision for optimal periodontal reconstruction, preserving supra-alveolar soft tissue integrity.
