What is the Difference Between Basal Bone and Alveolar Bone?

The main difference between basal bone and alveolar bone lies in their location, function, and structure within the maxilla and mandible, which are the bones that form the lower and upper jaws, respectively. Here are the key differences between basal bone and alveolar bone:

• Location: Basal bone forms the osseous tissue of the maxilla and mandible, except for the alveolar process. In contrast, alveolar bone is the thin bone that lines the alveoli, which are the sockets in the jaw that hold the teeth.
• Function: Basal bone provides a framework for the dental structure and forms the structure of the dental skeleton. Alveolar bone, on the other hand, renders support to the teeth and is involved in the formation of the alveolar process.
• Size and Structure: Basal bone is relatively larger, and its length increases with time. Alveolar bone is smaller in comparison to the basal bone and can be resorbed with age. Alveolar bone is a fine plate of bone with numerous perforations to allow blood vessels and nerves to reach the tooth.
• Formation: Basal bone takes form in the fetus, while alveolar bone develops from the dental follicle.
• Density: Basal bone is denser and less porous than alveolar bone, as observed through micro-computed tomography.

Comparative Table: Basal Bone vs Alveolar Bone

Basal bone and alveolar bone are two types of bones found in the maxilla and mandible, which are the bones that form the lower and upper jaws, respectively. They have different characteristics and functions:

Both basal and alveolar bones are dynamic structures that adapt to their environment and are essential for various functions, such as antigravity locomotion and mastication.
