Dual Scan vs. Single Scan

Dual Scan versus Single Scan. In fact, this is a single scan radio-opaque scannoguide masked as base-plate (green) and teeth (red) and again as a single (dual-scan like) stent (all green) for comparison purposes.

Dual Scan: A radiolucent stent with radiographic markers (Gutta-percha or other). Two CTs are needed, patient+stent and stent alone.

Single Scan: A radio-opaque stent (base-plate 10% Barium Sulfate - teeth 30% Barium Sulfate). One CT patient+stent is needed.
