The reduction of the enamel on the labial surface of the affected teeth makes the procedure irreversible. However, the procedures provide a superior functional and, more importantly, physiological result while still offering a conservative type of treatment. The uniqueness of the technique is in its ability to restore the physiological relationship of the gingiva and the labial surface, rather than to compromise this relationship by making a bulbous tooth of a greater labiolingual dimension than a normal tooth. It must be explained to the patients who require this type of procedure that the next step would be the complete reduction of the affected teeth and the construction of porcelain jacket crowns.
