Intracoronal Precision. Zero Binding.
Inlay design requires a different strategy than crowns. The internal fit must be precise, yet passive enough to seat without fracturing the thin ceramic walls. Common issues like “binding” at the line angles are caused by ignoring the limitations of the milling machine.
At China Dental Designer, your dedicated technician specializes in Drill Radius Compensation. We actively block out sharp internal corners in the design software (Exocad/3Shape) to match your specific bur size, ensuring the Dental Inlay Design seats fully without manual adjustment.
Technical Engineering Specifications
We tailor the cement gap and spacer settings to accommodate conservative preparations:
Fit Parameters
- Cement Gap: Slightly increased (40-60µm) to prevent hydraulic pressure build-up during seating.
- Undercuts: Strictly blocked out relative to the path of insertion to ensure passive fit.
- Margins: Smooth, ditch-free margins to prevent recurrent decay and chipping.
Morphology & Strength
- Occlusal Anatomy: Deep fissures (if material allows) or soft anatomy for easy polishing.
- Contacts: Designed broad and firm to prevent food impaction in Class II restorations.
- Isthmus Thickness: Maintained above 1.5mm at the stress-bearing zone to prevent fracture.
Why Assign Inlays to a Remote Team?
Designing a complex MOD inlay takes precision and time. Often, the prep is not ideal. Your remote specialist at China Dental Designer knows how to handle non-ideal preps by digitally blocking out undercuts, saving you the hassle of calling the doctor for a re-prep. We turn your digital scans into ready-to-mill files overnight.
Seamless Overnight Workflow
- Scan: Upload your intraoral scan. Ensure interproximal margins are captured clearly.
- Specify: Material (e.g., E.max, Cerasmart) and your Bur Size (for compensation).
- Receive: Download the STL file by 8:00 AM EST.
