Complex Cases. Simplified Engineering.
All-on-X cases are the highest liability for any lab. A broken bar or a chipped zirconia bridge can cost thousands of dollars. China Dental Labo offers specialized **All-on-X Design Services** focused on structural integrity. We don’t just connect the implants; we engineer a beam structure that withstands occlusal forces while maintaining esthetics.
Technical Engineering Specifications
We tailor the design based on your material choice (Zirconia, Metal, or Peek) and clinical requirements:
Bar Architecture
- Thimble Bar (Split Design): We design a substructure (Metal/Trinia/Zirconia) with individual “thimbles” and a superstructure of individual crowns or veneer. This mimics natural teeth and prevents full-arch stress fractures.
- Monolithic Zirconia: Full contour design with “Cut-back” only in the gingival area for pink porcelain layering.
- Wrap-Around: Classic metal bar design for acrylic processing.
Hygienic Profile
- Convex Intaglio: We sculpt the tissue side to be convex (boat bottom shape) to ensure the patient can clean underneath with Superfloss, preventing peri-implantitis.
- Screw Channels: We utilize Angulated Screw Channels (ASC) to redirect screw access holes to the lingual, avoiding facial aesthetic compromise (up to 25 degrees).
The Workflow: Verification is Key
For All-on-X, we recommend a Double-Digital Workflow to ensure zero errors:
- PMMA Prototype: Send us the scan. We design a monolithic PMMA prototype first.
- Try-in: You print/mill the PMMA. The doctor tries it in, checks occlusion, and verifies the passive fit (Sheffield Test).
- Wash Scan: If changes are needed, the doctor takes a wash impression inside the PMMA or scans the adjustments.
- Final Design: We update the design based on the verified prototype for the final Zirconia milling.
Library Compatibility
We support all major Multi-Unit Abutment (MUA) libraries:
- Premium: Nobel Biocare Multi-Unit, Straumann SRA, Zimmer.
- Value: Neodent GM/CM, Dess, Rosen, TruAbutment.
Start with a Prototype
Don’t risk milling a Zirconia puck on the first go. Let us design a Verification Jig or PMMA Prototype for your next big case.

Frequently Asked Questions
- Can you design Thimble Bars?
Yes, Thimble bars are our specialty. We can provide the STL for the bar and the separate STLs for the coping crowns. - Do you handle Photogrammetry scans (ICam4D)?
Yes, we are experienced in aligning ICam4D/Picasso implant position files with intraoral tissue scans.
