Modified coronally positioned flap for obtaining new attachment in class 2 and 3 furcation defects. Part I: Rationale and surgical technique
A new technique, the modified coronally positioned flap precedure, is described for treatment of Class 2 and 3 molar furcation defects in conjunction with barrier membranes. This technique is designed to minimize barrier exposure during the healing phase and to cover and protect the newly formed granulation tissue following barrier removal. Examples are presented and discussed, and modifications for varying situations are described. The modified coronally positioned flap technique is applicable for use with nonresorbable and resorbable membranes.
