Dental Assistant Practice Exam

What anatomical structure forms the sockets that support teeth?

1. Mandible

2. Gingiva

3. Alveolar Process

4. Maxilla

The correct answer is: Alveolar Process

The anatomical structure that forms the sockets supporting teeth is known as the alveolar process. This structure consists of the bone that encases the roots of the teeth, creating the bony sockets (or alveoli) into which the teeth are anchored. The alveolar process is critical for the stability and support of the teeth, as it provides the necessary bone density and anchorage for effective chewing and overall dental function. The mandible and the maxilla are the two main bones in the jaw that house the alveolar processes. While both the mandible (lower jaw) and maxilla (upper jaw) provide important structural support and housing for the teeth, they are not specifically responsible for forming the sockets. Gingiva, or gums, refers to the soft tissue surrounding the teeth and does not contribute to the bony structure that forms the sockets. Thus, the alveolar process is specifically identified as the correct answer, as it encompasses the crucial bony material that directly supports the teeth within their sockets.
