- Strictly Secure (HIPAA): Patient data is protected via encrypted portals and strict NDAs.
- Overnight Turnaround: Upload at the end of your day, download ready-to-mill files the next morning.
- Quality Guarantee: Fast, free design revisions until you are completely satisfied with the digital fit.
The End of Manual Wax Patterns. Start 3D Printing.
Hand-waxing a post and core is incredibly time-consuming, highly dependent on technician skill, and extremely prone to casting distortion. China Dental Design utilizes advanced offshore CAD workflows to deliver premium Post and Core CAD Design services. We engineer digital files that fit passively yet retentively. By directly 3D printing our digital patterns in Castable Wax or Resin, your US lab achieves a denser, distortion-free casting with absolutely zero rocking.
Technical CAD Engineering Specifications
Designing a precise post requires a deep understanding of endodontic root anatomy. Our master technicians engineer foolproof digital solutions, even for the most complex, divergent canals:
Digital Fit & Retention
- Cement Gap Control: We digitally set a precise cement spacer (e.g., 0.04mm) to ensure the post slides fully into the canal without hydrostatic pressure buildup.
- Anti-Rotation Features: Keyways are intelligently designed into the core to completely prevent rotation on single-rooted teeth.
- Ferrule Effect: We optimize the core geometry to respect the critical 2mm ferrule rule, ensuring long-term structural integrity for the final crown.
Complex Endodontic Solutions
- Split-Core (Lock & Key): For severe divergent multi-rooted molars, we engineer a 2-piece “Split-Cast” post. The primary post is seated first, seamlessly followed by the secondary locking post.
- Scan Post Workflow: We accurately align the digital post to your specific Scan Post library (3Shape/Exocad) for exact depth and angulation calculation.
Versatile Manufacturing Applications
Our Post and Core CAD Design files are exported as open STLs, fully optimized for your preferred in-house manufacturing method:
- 3D Printed Resin/Wax: Print and burnout for traditional High-Noble Gold or Non-Precious metal casting.
- Milled Zirconia: For high-esthetic anterior cases (requires specific zirconia block geometries).
- Milled Hybrid: Perfect for fiber-reinforced composite blocks.
Seamless Overnight Digital Workflow
- Secure Upload: Insert “Scan Posts” into the patient’s canals, take the intraoral scan, and upload via our 100% HIPAA-compliant portal. (Direct intraoral canal scanning without posts is not recommended due to depth limitations).
- Prescribe: Specify “One-piece” or “Split-Cast” design and indicate your desired core reduction parameters.
- Expert Design: We execute the design natively in Exocad or 3Shape overnight.
- Download & Produce: Download the STL file the next morning. Print in your lab, invest, and cast effortlessly.
