<jats:p><jats:bold>Introduction:</jats:bold> Aggressive periodontitis (AgP) is a form of periodontitis characterized by rapid attachment loss in otherwise healthy individuals. Although different treatment options have been explored for management of the disease, control of disease progression and subsequent regeneration of the attachment apparatus are considered the ideal treatment objectives. Limited evidence is available with respect to the efficacy of different regenerative materials in the treatment of AgP.</jats:p><jats:p><jats:bold>Case Presentation:</jats:bold> The present case report describes periodontal regeneration techniques and 6‐month outcomes in bilateral intrabony non‐contained defects around mandibular first molars in a 21‐year‐old patient diagnosed with localized AgP (LAgP). Periodontal lesions were treated with regenerative therapy with enamel matrix derivative (EMD) and allograft on the right side and allograft with bioabsorbable collagen membrane without EMD on the left side. Treatment yielded favorable clinical outcomes in terms of probing depth reduction, clinical attachment level gain, minimal gingival inflammation, and radiographic bone fill. Radiographic bone fill was observed after 6 months, suggesting possible periodontal regeneration.</jats:p><jats:p><jats:bold>Conclusion:</jats:bold> Both regeneration techniques used in this clinical report (guided tissue regeneration involving allograft and bioabsorbable membrane versus EMD combined with allograft without a barrier membrane) resulted in favorable outcomes in the treatment of deep (≥7 mm) non‐contained intrabony defects in LAgP.</jats:p>
