ABSTRACT

The concept of the ferrule effect has changed over the years, with adhesive restorations now allowing the effect to be achieved when fiber posts are used. Minimally invasive dentistry has sought to bring about a change in thinking and approach in the rehabilitation of endodontically treated teeth, based on systematic respect for tooth structures, given that these form part of the ferrule effect. The ferrule effect requires a minimum height of 2 mm of healthy tooth structure with 1 mm thickness 360^o around the circumference in order to ensure that the prosthetic restoration grips the remaining stump. When a sufficient ferrule effect is achieved, debonding of the restoration and/or fracturing of the root are avoided, so ensuring long-term success.
