I21D-400G (PE-ANA001)- Upper and lower jaw model with transparent gingivae and 28 anatomically rooted removable teeth. Superior dental anatomy in comparison to other rooted model sets. Please choose which articulator you need. The standard articulator (hinge) is a "D" articulator which holds the upper and lower arch together but cannot be used with any of our mounting systems. If you need to be able to place the model onto a pole mount you will need to choose the "DP" articulator.
