MINIMALY INVASIVE SURGICAL TECHNIQUE USING CHORION MEMBRANE IN THE TREATMENT OF INTRABONY DEFECTS ? CASE REPORT

The main purpose of periodontal treatment is to eliminate inflammatory processes in order to arrest the progression of the disease and keep the dentition in a state of the health. Thus the ultimate goal of periodontal therapy is to prevent further attachment loss and predictably restore the periodontal supporting structures that were lost because of disease or trauma in a way that the architecture and function of the lost structures can be re-established. Minimally invasive surgery (MIS) in the periodontal literature is used as a method of surgical access that minimizes flap reflection and tissue trauma, resulting in maintenance of critical blood supply, stability of the blood clot within the wound site, and less postoperative recession over time.Demineralized Bone Matrix (DBM) is an allograft with proven osteoinductive properties and biocompatibility. Chorion membrane has gained importance because of its ability to reduce scarring and inflammation; enhance wound healing; and serve as a scaffold for cell proliferation and differentiation as a result of its antimicrobial properties. The aim of this is to study was to clinically and radiographically evaluate the chorion membrane as a gtr membrane using minimally inavasive surgical technique. Within the limits of this study we reported that the use of chorion membrane in combination with DBM in minimally invasive surgical technique resulted in significant reductions in clinical parameters such as in PPD and CAL.
