CAD libraries in the digital workflow

CAD libraries as a geometric bridge between scanning and the component

TECH / LITE within the complete workflowIPD Solutions Map · clinic ↔ laboratory

A library is more than a database of names. It determines how CAD software interprets the scanned scan body and how that position is translated into the final prosthetic geometry.

Digital workflowEditorial translationPractical commentary

Editorial note: This English page is based on an educational article by IPD USA. The content has been translated, condensed and terminologically aligned with this website, while absolute marketing statements have been replaced with a more practical interpretation for the dental practice and laboratory.

Why the library is part of the accuracy chain

An intraoral scanner creates surface data, but CAD software does not inherently know the exact implant coordinate from that surface alone. The coordinate is established by matching the scanned scan body to the reference geometry stored in the library. The implant, platform, scanning level and exact scan body must therefore all be selected correctly.

From the laboratory perspective, the library is a technological contract between the physical component and the virtual model. If the project contains geometry different from what the library expects, the software may produce a convincing-looking best fit that does not correspond to the intended prosthetic workflow.

TECH and LITE: the difference is in the input geometry

TECHUses defined IPD scan-body geometry and is suitable when the complete digital chain is to be controlled within the IPD system.

LITEExtends flexibility to supported OEM or selected third-party scan bodies. The key word is supported: matching the platform alone is not sufficient.

Full-arch and multi-implantAs the distance between implants increases, accumulated deviations become more significant, making disciplined use of one verified geometry increasingly important.

3D modelThe library workflow does not end in CAD. With digital analogs, it must also correspond to the receptacle geometry and the calibration of the specific printing process.

Example at MUA level

The practical page shows when TECH starts from IPD scan-body geometry and when LITE starts from a supported OEM/third-party MUA scan body, including the link to Exocad.

Pre-design checks

Which implant system, model and prosthetic platform are actually used in the case?
Was the scan acquired at implant level, Multi-Unit abutment level or another prosthetic level?
What is the exact scan-body reference, and is it intended for the selected library branch?
What is the intended restoration type: single crown, bridge, full-arch, Ti-base or custom abutment?
Is the library current for the version of Exocad, 3Shape or Dental Wings being used?

Important editorial clarification of the source article

The original US text uses very strong language about “absolute” and “micrometric” accuracy. In practice, accuracy is always the result of the complete measurement and manufacturing chain. We therefore present the concept as guidance for controlling geometric continuity, not as a guarantee of zero deviation.
