Guided Tissue Regeneration in Esthetic Zone by Whale's Tail Flap Design Using Indigenously Prepared Dfdba and Amniotic Membrane: A Case Report

Abstract

Anticipation of complete reconstruction of lost periodontal tissues destroyed by periodontal disease is still a major challenge. Flap design in periodontal regeneration procedure should be such that to preserve maximum tissue and allow complete stabilization of the graft placed. Bone grafts are used in the treatment of various maxillomandibular bone defects, including Intrabony defects and Furcation defects. Allografts such as DFDBA, FDBA, amnion membrane, chorion membrane and amnion-chorion membrane are processed and stored according to standard protocols in central tissue bank, MAIDS New Delhi. The purpose of this case report is to describe and evaluate the efcacy of the “whale's tail” technique that was designed for the treatment of wide intrabony defects in the esthetic zone. Indigenously prepared DFDBA bone allograft and amniotic membrane used in the regeneration of osseous defect shows radiographic bone ll and pocket reduction from 7mm to 3 mm 18 months postoperatively
