Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators will test the hypotheses:
* There is no systematic difference between measurements taken from the Trios scanner and study models.
* There is no difference in the cost of producing digital models.
