Overview
The objective of this study was to assess the effectiveness of NIPSA in periodontal lesions with deep supra-alveolar defects, measuring the clinical efficacy of this flap. The non-incised papilla surgical approach (NIPSA) is a novel technique that accesses the periodontal defect from apical direction and was established with the aim of creating clinical advances compared with marginal access techniques.
The defects with a supra-alveolar components are more frequent than intrabony defects, there is very little evidence about their treatment .
