In 1975, Bjorn L Dahl from the Faculty of Dentistry of the University of Oslo became the first author through a series of papers to report the successful use of this technique for the management of the worn dentition.[4] Along with Olaf Kronstadt and Kjell Karlsen, Dahl described the use of a bite-raising appliance to increase the available interocclusal space available for future restorations.[4] The removable appliance was originally cast in cobalt chromium and placed on the palatal aspects of an 18-year-old’s upper incisors which had been subject to localised attrition. Over a period of eight months, the appliance was worn 24 hours a day and over time enough space was created to allow the application of palatal gold inlays to the worn upper incisors.[2] Dahl found that it was a combination of intrusion of the anterior teeth in contact with the appliance (40%) and passive eruption of the unopposed posterior teeth (60%) that permitted the reestablishment of posterior occlusion whilst maintaining the interocclusal space.[5]
