Abstract: Highlights•Diffusion network fusing 3D crowns & 2D radiographs for complete tooth generation.•CBCT-to-radiograph synthesis via elliptical projection solves 3D-2D training bottleneck.•Multimodal guidance enforces 3D geometry accuracy and 2D radiograph consistency.•3D shape and differentiable projection alignment for clinical root features.
