Periodontal Regeneration in Mandibular Intrabony defects using DFDBA with chorion membrane vrs DFDBA with collagen membrane and I-PRF augmentation in mandibular supra-bony defects: A Split Mouth Case Report

AbstractThis split mouth case study evaluates the regeneration effectiveness of injectable platelet rich fibrin (I-PRF) augmentation for related suprabony lesions and demineralized freeze dried bone allograft (DFDBA) in conjunction with either chorion or collagen membranes in mandibular intrabony defects. Clinical and radiological characteristics were assessed at baseline and six months after regenerative treatment for a systemically healthy patient with bilateral periodontal abnormalities. The DFDBA chorion membrane site showed marginally better tissue integration and radiographic bone regeneration, although both membrane assisted DFDBA techniques produced significant decreases in probing depth, increases in clinical attachment, and considerable defect fill. In suprabony deformities, concurrent use of I-PRF improved early soft-tissue healing and supported overall surgical results.This paper emphasizes the combined effects of membrane selection and biologic augmentation in promoting periodontal regeneration.
