Professional Dental Onlay Design Service
When a tooth is too damaged for a filling but still has enough structure to avoid a full crown, the Onlay is the perfect “middle ground.” At India Dental Design, our Dental Onlay Design service focuses on Cusp Capping logic. We restore the occlusal table while preserving the healthy cervical tooth structure.
Our designs are engineered to distribute occlusal forces evenly, protecting the underlying tooth from vertical fractures while ensuring the restoration itself is thick enough to withstand chewing pressure.
🛠 Technical Specifications
- Cusp Thickness: Min 1.5mm (Ceramic) / 1.0mm (Zirconia) for load bearing.
- Margin Design: Butt-joint (Ceramic) or Chamfer (Zirconia) as per prep.
- Drill Compensation: Optimized for smooth internal fit.
- Undercut Block-out: Calculated insertion path.
- Cement Gap: 0.050mm – 0.080mm (Customizable).
- Occlusion: Anatomical design with proper fissure depth.
Why Labs Outsource Onlays to Us?
1. Biomechanical Strength
Onlays fail when they are too thin at the “Isthmus” or the Cusp tip. We use CAD heat maps to verify minimum thickness, ensuring the material won’t crack after cementation.
2. Margin Transition
The transition from porcelain to tooth needs to be invisible. We design smooth, continuous margins that allow your technicians to polish quickly without ditching the restoration.
3. Undercut Management
Onlay preps often have complex geometries. We carefully set the Path of Insertion and block out undercuts digitally, so the restoration seats passively without binding.
4. Material Versatility
Whether you are milling E.max, Zirconia, or Hybrid Ceramics (Cerasmart/Lava Ultimate), we adjust the drill compensation parameters to suit the material’s chippiness factor.
Digital Workflow
Seamless integration for conservative dentistry:
- 📥 Step 1: Upload IOS scans or desktop scans.
- 💻 Step 2: Our team verifies the preparation margins and designs the cusp coverage.
- ⚙️ Step 3: Download mill-ready STL files the next morning.
Test Our Fit & Aesthetics
Send us 3 Onlay cases. We will design them for free so you can verify the seating.
