Summary

Orthodontic and dental models have pedestals that finish the model. Readily changeable and scalable.

Instructions

Made in openscad. It's an amazing program. I'm very new to this.

Upper model code:
linear_extrude(height = 20, center = true, convexity = 10, twist = 0)
polygon(points=[[0,20],[15,0],[85,0],[100,20],[80,55],[50,75],[20,55]], paths=[[0,1,2,3,4,5,6,7]]);

Lower model code:
linear_extrude(height = 20, center = false, convexity = 10, twist = 0)
polygon(points=[[0,20],[15,0],[85,0],[100,20],[80,53],[50,69],[20,53]], paths=[[0,1,2,3,4,5,6,7]]);
translate([50,39,0])
cylinder(h = 20, r=33.1);

I'm sure code could be better.
