What does the term 'impression' signify in dentistry?
Negative print of the teeth and tissues
Positive mold for creating restorations
Imprint of the teeth and tissues
A type of dental x-ray
The correct answer is: Imprint of the teeth and tissues
In dentistry, the term 'impression' generally refers to capturing a detailed negative print of the teeth and surrounding oral tissues. This negative imprint is crucial for creating accurate and customized models of a patient's dental anatomy, which are then used for various purposes such as fabricating crowns, bridges, dentures, or other dental restorations. A well-taken impression ensures that any subsequent dental work fits precisely within the patient's mouth. This understanding highlights that while the suggestion of an imprint makes sense, the more precise term 'negative print' better captures the technical aspect of what an impression entails, as it directly informs the process of creating positive molds for dental restorations.
