License clarification for source code, pretrained checkpoints, and commercial use

[millswu]

Hello ToothGroupNetwork authors,

Thank you for releasing ToothGroupNetwork and the pretrained checkpoints.

We are evaluating the project for AxisGuide, a locally deployed dental medical software application. Before performing any commercial integration, we would appreciate clarification of the licensing terms.

The repository currently does not appear to contain a LICENSE file. Could you please clarify:

1. Under what license is the ToothGroupNetwork source code released?
2. May the source code be used, modified, and incorporated into commercial software?
3. Under what license are the pretrained checkpoints released?
4. May the provided checkpoints be used for commercial inference or embedded in a commercial product?
5. Were the checkpoint weights trained only on the 3DTeethSeg / Teeth3DS challenge dataset, and do you have the necessary rights to authorize commercial use of those weights?
6. If commercial use of the provided checkpoints is not permitted, may we use or modify the source code and train new weights exclusively on our own legally obtained data?
7. Are there attribution, publication, patent, redistribution, or model-distribution requirements that we should follow?

We are interested in local/offline deployment rather than a hosted API.

A public clarification in the repository, ideally through an explicit LICENSE file and a separate model-weight license, would also help other users avoid misunderstanding the permitted uses.

Thank you for your time and for making this work available.

Best regards,

Maria Zhu
