The file was sent to the New Ancorvis milling centre for the production of a Cr-Co bar. After a few days, the bar was returned to the laboratory, and tried first on the replica model to ensure its accuracy and pas- sivity (Fig. 22); then the bar was positioned on the master model to verify it was a good fit even com- pared to the soft tissues, the cuff height and the cor- rect spaces for hygiene (Figs. 23 & 24). After that the bar was sent to the dentist to double check the preci- sion, passivity, correct spaces for hygiene, with the help of X-rays (Figs. 25–28). After those checks had been carried out, the bar was finished and polished. At this stage, the attachments were chosen accordingly to the type of prosthesis and the project and screwed into the structure (Fig. 29). Once the attachments were screwed in, the bar was thoroughly polished (Fig. 30). The counter-bar was produced, polished and the retentive caps were in- serted (Figs. 31 & 32). With the help of silicone masks, the teeth were repositioned and waxed on the super- structure, for the final try-in in the mouth (Figs. 33–35). A final check that everything had been completed was Fig. 37 Fig. 37: The prosthesis after the resin is finished. Figs. 38 & 39: Front teeth and vestibular lateral flange after the polishing.
