    The alveolar crests of the adjacent teeth are also uniform in height along the jaw when they are healthy. The supporting alveolar bone structure consists of both cortical and trabecular bone. The cortical bone, also known as cortical plates, consist of plates of compact bone found on the facial and lingual surfaces of the alveolar bone. These cortical plates are typically about 1.5-3 mm thick compared to the

  • Alveolar Process - Assignment Point

    Cortical bone contains cortical plates which have perforations in the anterior teeth, for the entry of blood vessels into the inner parts of the teeth. The cortical plates are least in the maxillary region and the highest are seen in the molar region of the mandibular bone. Spongy bone also called Spongiosa, contains trabeculae. The spongy bone is further divided into 2 types — Type I & Type II.

    It consists of two plates of cortical bone separated by spongy bone (Fig. 1.149). In some areas, the alveolar bone is thin with no spongy bone (Fig. 1.148). The alveolar bone and the cortical plates are thickest in the mandible. The spaces between the trabeculae of the spongy bone are filled with marrow, which consists of haematopoietic tissue in early life and of fatty tissue later (Fig. 1,
