HOSA Dental Terminology Practice

Which part of the jaw forms the dental arch and contains the sockets for the teeth?

1. Calvarial process

2. Alveolar process

3. Operculum

4. Condyle

The correct answer is: Alveolar process

The alveolar process is the correct answer because it specifically refers to the bony ridge in the jaw that contains the sockets for the teeth, known as alveoli. This structure supports the teeth and is crucial for their stability and alignment within the dental arch. The alveolar process is found in both the upper and lower jaws, contributing to the overall shape of the mouth and playing a significant role in dental health. In contrast, the calvarial process refers to the upper part of the skull and does not have any direct connection to the dental arch or the sockets for teeth. The operculum is a flap of tissue that can cover a partially erupted tooth, such as a wisdom tooth, but it does not form the bony structure needed for tooth retention. The condyle is part of the temporomandibular joint (TMJ) that connects the jaw to the skull, playing a role in jaw movement, but it is not involved in forming the dental arch or holding teeth in place.
