A double-cord impression technique for prepared teeth and a closed-tray impression technique with the impression abutments in position for the implants were performed to pro- duce final impressions using a silicone impres- sion material (Aquasil Ultra, Dentsply Sirona, York, Pa., U.S.). The milled PMMA provisionals, sectioned into sextants, were relined with self-curing acrylic resin (Jet Acrylic, Lang Dental, Wheeling, Ill., U.S.). Casts made from the final impressions were cross mounted with casts of the provisional restorations. All of the dies and casts were scanned with the 3Shape D700 for custom titanium abutments (Atlantis, Dentsply Sirona, York, Pa., U.S.) to be designed based on a copy of the virtual wax-up. The custom abutments were manufactured, and the CADs of the final restorations were then copy-milled into wax prototypes by the dental laboratory with the purpose of using them as templates for the final restorations. The milled wax prototype was tried in for an occlusal and esthetic evaluation (Figs. 7 & 8). Both arches were evaluated and no occlusal adjustments were necessary in centric relation and during excursive movements. Minimal reduction of the incisal edges was performed to make the esthet- ics more age-appropriate.13 The case was sent to the dental laboratory for the fabrication of the final restorations. Final characterization was done, followed by glazing and polishing (Table 1). At delivery, the posterior metal–ceramic res- torations and anterior IPS e.max pressed restora tions were approved by the patient for Journal of Oral Science & Rehabilitation Volume 3 | Issue 4/2017 45
