Optimal Porcelain Support. Zero Fractures.
A ceramic restoration is only as strong as the framework beneath it. Many outsourced designs fail because they leave the porcelain unsupported, leading to chipping or cracking. At China Dental Design, our premier Dental Coping CAD Design service strictly utilizes “Anatomic Cut-back Engineering”.
We don’t simply reduce a tooth shape randomly; we anatomically support the cusps. Whether your US lab is producing PFM (Porcelain Fused to Metal) or PFZ (Zirconia substructures), our designs guarantee a uniform layer of porcelain (e.g., 1.0mm – 1.5mm) for maximum aesthetics and long-term durability.
Technical CAD Engineering Specifications
We tailor every Dental Coping CAD Design parameter to your specific in-house manufacturing workflow, whether you use SLM metal printers or 5-axis milling machines:
Structural CAD Parameters
- Minimum Thickness: Precisely set to 0.3mm (Metal) or 0.5mm (Zirconia) to ensure milling integrity and castability.
- Margin Reinforcement: Customizable options for metal collars (lingual/360°) or disappearing margins based on your Rx.
- Connector Design: For bridge frameworks, we calculate and maximize the connector surface area (min 9mm²) without impinging on the gingival embrasure.
Anatomic Porcelain Support
- Full Contour Reduction: We design the full contour first in 3Shape/Exocad, then reduce evenly to create the perfect underlying canvas for your ceramists.
- Rest Seats & Attachments: Precision digital integration for partial denture rests or precision attachments included at no extra cost.
Seamless Overnight Digital Workflow
- Upload Securely: Send your intraoral scans or desktop scan data via our HIPAA-compliant client portal. Indicate if you need specific cement gaps (e.g., 0.03mm for SLM vs 0.05mm for Zirconia).
- Prescribe: Specify the framework material (Co-Cr, Titanium, Zirconia) and your preferred finish line design.
- Expert Design: Our dedicated technicians execute the design natively in Exocad/3Shape overnight.
- Download & Produce: Download your open, mill-ready STL file the next morning and send it directly to your SLM printer or milling unit.
