Advantages of a new post design, Flexi-Flange are described. It incorporates a split-shank parallel threaded post with a flange that seats into an occlusal countersunk dentine space. This case report describes placement of three Flexi-Flange posts in a first bicuspid, canine and central incisor. The Flexi-Flange system was designed to offer high retention of the post in the root, superior distribution of stresses on insertion and under function, and long-term resistance to metal fatigue.
