The dental CAD/CAM market has three serious players: Exocad, 3Shape and MillBox. Each solves a different task.
Exocad DentalCAD
Exocad DentalCAD is the most modular system. Base license covers crowns, bridges, veneers. Additional modules added as the lab grows.
Open STL format means you're not tied to a single scanner ecosystem.
3Shape Dental System
3Shape Dental System — closed but cohesive ecosystem: TRIOS scanner → Dental System.
MillBox
MillBox takes STL from any CAD (inLab CAD/CAM too) and generates milling paths.
What to choose
Starting lab → Exocad base. Clinic with 3Shape scanning → 3Shape Dental System. Production lab → CAD + MillBox.
