What are the two parts of a dental model?

  1. Functional and aesthetic

  2. Anatomic and art

  3. Base and crown

  4. Model and mold

The correct answer is: Anatomic and art

A dental model consists of two parts anatomic and art. These two parts work together to create a detailed and accurate representation of a patient's teeth and mouth structure. Option A is incorrect because while functional and aesthetic are important aspects of dental care, they do not accurately describe the two parts of a dental model. Option C is incorrect because a base and crown are components of a tooth, not a dental model. Option D is incorrect because a model and mold are both used to create a dental model, but they are not the two specific parts of the model itself. The most accurate and complete answer is B, anatomic and art.
