HOSA Dental Terminology Practice

Which part of the bone forms the sockets for the teeth in the maxillae and mandible?

1. Alveolar Process

2. Cortical Bone

3. Spongy Bone

4. Maxillary Bone

The correct answer is: Alveolar Process

The alveolar process is the correct answer because it is the bony ridge found in both the maxilla (upper jaw) and the mandible (lower jaw) that contains the sockets, or alveoli, for the roots of the teeth. This specialized structure plays a crucial role in tooth anchorage, providing support and stability to the teeth within the dental arch. The alveolar process is covered by gingiva (gums) and is vital for proper dental function, as it facilitates the interaction between teeth and the jawbone during activities such as chewing and speaking. Its health and integrity are essential in the context of periodontal disease and dental implants, as the loss or degradation of the alveolar process can lead to complications in maintaining oral health and restoring lost teeth. Other structures mentioned, such as cortical bone and spongy bone, do not specifically create the sockets for teeth, although they are components of the overall bone structure. The maxillary bone itself refers to the upper jaw bone but does not specifically indicate the part that forms the sockets for teeth.
