I already have a Kilgore or Columbia Dentoform model, what's the difference?
We answer this question quite a bit and thought it might be helpful to address.  They might all look the same but like other models there are subtle differences between the various models which make a huge difference when cutting or working on the teeth.

Compared to the typical D95 200 series Kilgore model the ANA-4 features similar morphology, larger teeth and much harder material for the teeth making it difficult to compare practice on one to the other. 

Compared to the Columbia Dentoform 860 series model the teeth are similar in hardness but the shape and morphology is different. 

While any model can be used as a substitute the only way to accurately reproduce examination conditions is to practice on the same model used by the program.
