Complete Dual-Arch All-on-4® Rehabilitation Using a Fully Digital Workflow: A Case Report

Area of Science:

• Dentistry
• Digital Dentistry
• Prosthodontics

Background:

• Full-arch rehabilitations present complex challenges in achieving optimal function and esthetics.
• Traditional workflows can be time-consuming and prone to inaccuracies.
• The All-on-4 concept offers a minimally invasive solution for edentulous patients.

Purpose of the Study:

• To present a case report on a fully digital workflow for dual-arch All-on-4 rehabilitation.
• To highlight the integration of various digital technologies in the treatment process.
• To evaluate the accuracy, efficiency, and patient satisfaction achieved with this digital approach.

Main Methods:

• Utilized intraoral and facial scanning, mandibular motion tracking, and digital smile design.
• Employed prosthetically driven implant planning and 3D-printed surgical guides for guided surgery.
• Fabricated computer-aided design/computer-aided manufacturing (CAD/CAM) titanium frameworks with zirconia superstructures for definitive prostheses.

Main Results:

• Achieved precise implant placement and accurate passive fit of the definitive prostheses.
• Validated stable occlusion through functional motion capture and dynamic jaw-motion recording.
• Delivered highly esthetic outcomes with screw-retained, full-arch restorations, demonstrating high patient satisfaction.

Conclusions:

• A fully digital All-on-4 workflow can significantly enhance accuracy and efficiency in complex full-arch rehabilitations.
• The integration of digital technologies facilitates minimally invasive treatment with predictable, esthetic results.
• This approach optimizes treatment outcomes and patient satisfaction for full-arch restorations.
