TSegAgent: Zero-Shot Tooth Segmentation via Geometry-Aware Vision-Language Agents

Guangshun Wei, Lu Yin, Shaojie Zhuang, Xilu Wang, Yuanfeng Zhou, Yunpeng Li

TSegAgent achieves zero-shot tooth segmentation in 3D dental scans by turning the task into geometry-grounded reasoning with vision-language agents.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experimental results demonstrate that this reasoning-oriented formulation enables accurate and reliable tooth segmentation and identification with low computational and annotation cost, while exhibiting strong generalization across diverse and previously unseen dental scans.

C2weakest assumption

That multi-view visual abstraction combined with geometry-grounded reasoning from general foundation models can reliably infer tooth instances and identities solely from encoded dental anatomy constraints such as arch organization and volumetric relationships, without any task-specific training.

C3one line summary

TSegAgent achieves accurate zero-shot tooth segmentation on 3D dental scans via geometry-aware vision-language reasoning without task-specific training.
