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. 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. Please refer to I21DP-400G if you need to pole mount the model.
