Use of biomembrane in the treatment of class 3 Furcation defect

ABSTRACT

Eight patients included in this study where two surgical procedures were done for each one who has furcation grade III in both sites. One surgical site is treated by Gore-tex biomembrane that cover the furncated area, and the other site just mucoperiostial flap. Clinical parameters were recorded for evey patient after follow-up time [3and 6 months].The clinical and radiographic satisfactory results of this study clearly show that a good method of treatment aimed at restitution of the attachment apparatus lost in periodontal disease, can be based on the biological principle of guided tissue regeneration. From that we can conclude the followings The Gore-tex treatment resulted in more tissue growth outside as well as within furcation defects, which cause shallow probing depths in the partially healed furcation defects.-The size and the height of the furcation defect may be determining factors for success or failure following Gore-tex therapy at furcation defects. It seems that the larger and/or higher the detect, the smaller is the change for complete regeneration. Shallow and wide furcation defect has a greater chance for regeneration.-The important factor for the success of Gore-tex therapy at furcation may be the amount of periodontium that remains apical and/or lateral to the defect. That is, the smaller the amount of remaining periodontium, the smaller the amount of new attachement that may form.-from the present study, it could be recommended to use Gore-tex biomembrane in the treatment of shallow wide furcation class III defects
