Conservative prosthodontics: A case report

We do not take but we make an impression. To make an impression, we measure with our eyes and fingers, the anatomic limits of the oral cavity. Knowledge of the origins of the muscles of facial expression and of the anatomic landmarks is essential. If one knows the oral anatomy, both gross and histologic, he can readily decide how to make the impression, what material to use, and how to position the tissues when the impressions are made.
