The Middle Ground Between Filling and Crown.
Onlays (or Partial Crowns) are chemically retained restorations that require precise planning. The transition from the preparation margin to the restoration must be seamless to allow for proper cleaning and bonding.
At China Dental Designer, your dedicated technician excels in Biomimetic Design. We restore the tooth’s natural morphology while ensuring that the functional cusps are adequately protected (shaved down) to withstand masticatory forces.
Technical Engineering Specifications
We focus on “Drill Radius Compensation” to ensure these complex geometries fit your die perfectly:
Design Parameters
- Cusp Coverage: Minimum 1.5mm reduction ensured for E.max/Ceramic strength to prevent fracture.
- Internal Fit: Drill radius blocked out to prevent binding on sharp prep corners.
- Cement Gap: Optimized (50-60µm) for resin cement viscosity.
- Margins: Smooth, rolling margins to prevent chipping during the milling process.
Specialty Designs
- Tabletops (Occlusal Veneers): Minimal prep designs for raising VDO (Vertical Dimension) in wear cases.
- Vonlays: Combination of buccal veneer and occlusal onlay for premolars.
- 3/4 Crowns: Preserving the buccal wall for maximum aesthetics.
Why Assign Onlays to a Remote Team?
Onlays are tricky. If the prep has undercuts, the design software needs careful manual blocking to define a clean path of insertion. Instead of struggling with geometry issues, let your remote team at China Dental Designer handle it. We verify every file for manufacturability before sending it back.
Seamless Overnight Workflow
- Scan: Ensure the preparation margins are visible and distinct from the gums.
- Specify: Material (e.g., IPS e.max CAD) and desired contact strength.
- Receive: Download the STL file by 8:00 AM EST.
