Conservative Dentistry. Engineered Precision.
Inlay and Onlay preparations are often complex with sharp internal line angles. The biggest challenge for dental labs is “Binding” – when the milled restoration doesn’t seat because the milling bur couldn’t cut the sharp corners.
At China Dental Designer, your dedicated technician doesn’t just draw a line. We apply Drill Radius Compensation. We virtually “over-mill” the intaglio surface in the software to match your specific bur size (e.g., 0.6mm or 1.0mm), ensuring the restoration drops in perfectly without manual grinding.
Technical Engineering Specs
We tailor the design parameters to ensure longevity and fracture resistance:
Design Parameters
- Internal Gap: Optimized (50-80µm) to prevent hydraulic pressure during cementation.
- Isthmus Thickness: Maintained >1.5mm to prevent fracture at the stress-bearing zone.
- Undercuts: Strictly blocked out relative to the Path of Insertion.
- Margins: Smooth, chipping-resistant margins designed for milling stability.
Specialty Designs
- Tabletops (Occlusal Veneers): Minimal prep designs for raising VDO or treating erosion.
- Vonlays: Hybrid designs covering the buccal face and occlusal surface.
- Endo-Crowns: Monolithic restorations utilizing the pulp chamber for retention.
Why Hire a Remote Designer for Inlays?
Designing complex multi-surface inlays takes time and attention to detail. By assigning these cases to your remote team at China Dental Designer, you free up your local staff to focus on high-value finishing. We process your scans overnight, so your design files are ready to nest when you arrive in the morning.
Seamless Overnight Workflow
- Scan: Upload intraoral scans. Ensure interproximal margins are captured clearly.
- Specify: Material (e.g., IPS e.max CAD, Lava Ultimate) and Contact strength.
- Receive: Download the STL file by 8:00 AM EST.
Test Our Fit
Send us a Class II Inlay or a Tabletop case. We will prove that our drill compensation strategy works.
