- In the Annotations list (Actions → List), each measurement row has a tooth picker: choose the FDI number; the Universal number is shown in brackets (16 (3), 36 (19), primary teeth marked p).
- In the implant plan, each fixture row has the same picker for its site.
- The tooth travels with the study: it is saved with the annotations, written into the DICOM SR as the finding site ("Tooth 16 (ISO 3950 / FDI)") and prefixed to the label in the presentation state. Nothing is identified automatically — you pick the tooth.
