These days, indirect all-ceramic restorations are gaining in popularity all the time. They do, however, require special shapes to allow for the properties of the materials and to ensure firm fixation. To this end, preparation guidelines were compiled and special preparation instruments were developed to suit the requirements of all-ceramic inlays, partial crowns and crowns. High-strength dental ceramics – such as for example monolithic lithium silicate – allow less invasive types of preparation. These new preparations reduce the grinding trauma and the fitting of the restoration and therefore, the risk of pulpitis. In case of defects limited to the occlusal area, suitable alternatives might include occlusal onlays (also called table tops). These types of restorations are, however, difficult to prepare with traditional instruments. This prompted us to assemble a new sequence of preparation steps and develop appropriate new abrasive instruments that greatly facilitate the procedure.
