restoration of the edentulous maxilla case report | Fig. 7 Fig. 8 Fig. 7: Duplicated prosthesis in transparent resin positioned in the oral cavity after it has been perforated in correspondence of the impression copings. – Fig. 8: Final impression taken with the duplicated prosthesis. – Fig. 9: Resin template returned to the laboratory after it had been positioned in the oral cavity and joined to verify the implants’ position and the analogues’ position in the model. – Fig. 10: Check-up model to verify the implants’ position made with the resin template. Fig. 9 Fig. 10 Guided by the duplication of the teeth set-up (replica), the implants were placed in the most suit- able position and in a sufficient number to build a stable, aesthetic removable prosthesis without the palate. During the osseointegration period, the pa- tient was provided with a temporary prosthesis in the zones adjacent to the implants. After the period of osseointegration, the implants were inspected Fig. 11 Fig. 11: Occlusal view of the scanned Fig. 12 teeth set-up. The design of the most appropriate retentive solution to apply to the prosthesis begins. This view is critical for the positioning of the bar accordingly to the teeth, the crest, the position and the number of implants. Fig. 12: Front view of the scan. Fig. 13: Side view of the left scan. Fig. 14: Side view of the right scan, with these scans you can design the Fig. 13 Fig. 14 structure by checking the available spaces given by the teeth set-up.
