Digital Workflow for Full-Arch Implant-Supported Prosthesis Based on Intraoral Scans of a Relative of the Patient

Figure 1. (a) Initial clinical view of the full-arch implant-supported temporary prosthesis. (b) Initial occlusal view of the abutments without the temporary prosthesis. Figure 2. (a) Without the temporary prosthesis and using scan bodies for screw-retained abutments for digital scanning of maxillary implants. (b) Maxillary/mandibular casts and artificial gingiva printed 3-dimensionally using resins. Both casts are connected with a bar.

Figure 3. (a) The patient selected the dental arch shape and smile of her daughter as a base for her full-arch implant-supported prosthesis. The facial analysis of digital smile design methodology can be then used to confirm whether patients and relatives have similar esthetic characteristics. (b) Provisional polymethyl methacrylate (PMMA) fabricated from the digital design of the teeth adjusted to the main patient's esthetics. (c) PMMA prosthesis screwed in the implant analogues of the 3-dimensionally-printed casts to check occlusion and make occlusal adjustments. Figure 4. (a) Considering the final standard tessellation language file, a compatible zirconia framework was digitally designed and milled. (b) Final maxillary prosthesis with layered application of gingival and tooth-colored ceramic over the zirconia framework. (c) Patient's final natural smile.
