Monolithic Zirconia Full-Arch Rehabilitation Using a Motion-Integrated Digital Workflow Combining M-4 and All-On-4...

A 45-year-old edentulous woman presented for full-arch rehabilitation and was managed using a motionintegrated, 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 the occlusion, and definitive monolithic zirconia prostheses were fabricated and delivered on titanium multiunit abutments using Rosen screws. This streamlined digital approach addressed both functional and esthetic challenges, offering a personalized and efficient solution for immediate full-arch rehabilitation.
