What is the spongy layer of bone in the alveolar region referred to as?

The spongy layer of bone in the alveolar region is referred to as cancellous bone. This type of bone is characterized by its porous, lattice-like structure, which provides both strength and flexibility. Cancellous bone is found in various parts of the body, including the interior of the alveolar process, where it supports the structure and stability of the teeth. This porous composition facilitates the housing of bone marrow and the accommodation of blood vessels and nerves, contributing to the overall health and function of the jawbone and teeth.

In contrast, compact bone is denser and forms the outer layer of the bone structure, providing strength and support. Fibrous bone is not a standard classification within dental terminology, and cemental bone refers to the calcified tissue that covers the roots of teeth—this does not describe the spongy bone structure of the alveolar region.
