These were designed virtually and ordered from the DEDICAM fabrication service. The individual telescope abutments were inserted definitively and mounted with the torque recommended by the manufacturer (Figs. 31 to 33). The galvanically fabricated secondary crowns were placed on the primary crowns (Figs. 34 and 35). Tooth 16 as well as the LODI implants were extracted. The treatment protocol calls for intraoral bonding of the secondary crown to the tertiary framework, under confirmation of the determined bite registration (Figs. 36 and 37). A pick-up impression of the framework was then realized using an individual tray. As the abutments remain in the mouth with this concept, a specially Fig. 20: The prefabricated restoration was checked intraorally for tension-free status.
