Complex Engineering. Simplified Workflow.
Full arch restorations (All-on-4 / All-on-6) are the most technically demanding cases in a dental lab. They require a perfect balance of biology (hygiene), physics (load distribution), and art (esthetics).
Our Full Arch Design Service takes the burden off your senior technicians. Whether you need a PMMA Prototype for try-in or a final Zirconia Hybrid, we ensure passive fit and structural integrity overnight.
Technical Engineering Specs
We strictly adhere to biomechanical principles to prevent catastrophic failures:
Bar Design Types
- Thimble Bar: Titanium/Zirconia substructure with individual stumps for cementing single crowns (Maximum esthetics).
- Montreal / Hader Bar: For clip-on overdentures.
- Wrap-Around / Hybrid: Metal bar completely encased in acrylic/composite.
- Monolithic Zirconia: Full contour with cut-back for pink porcelain.
Safety Parameters
- Cantilevers: Strictly calculated based on the AP (Anterior-Posterior) Spread to prevent distal fracture.
- Intaglio Surface: Convex (ovoid) design to allow Superfloss/Waterpik cleaning. No ridge-lapping ridges.
- Screw Channels: Angled (ASC) correction to hide access holes.
Why Outsource All-on-X?
A single All-on-X design can take 2-4 hours of intense CAD work. By outsourcing to China Dental Designs, you free up your workstations for other tasks. We handle the heavy lifting: library matching, bar nesting preparation, and gingival contouring.
Submission Workflow
- Scan: Upload MUA level scans (or fixture level), Soft Tissue scan, and Opposing.
- Records: Include Bite Registration and Vertical Dimension (VDO) information.
- Receive: Download the STL file by 8:00 AM EST.
