Monolithic Zirconia Full-Arch Rehabilitation Using Digital Technology

20 edentulous patients presented for full-arch rehabilitation and was managed using a motion-integrated, fully digital workflow that combined the M-4 protocol in the maxilla with the All-on-4 concept in the mandible. Dual-scan CBCT and facial scans enabled prosthetically driven planning, while stackable and mucosa-supported surgical guides facilitated precise implant placement. Real-time jaw-motion data were incorporated into the design process to individualize occlusion, and definitive monolithic zirconia prostheses were fabricated and delivered on titanium multi-unit abutments using Rosen screws.
