WebJul 25, 2024 · The primary epithelial band develops into the vestibular and dental laminae. The vestibular lamina forms the free space between the cheek and the alveolar process. The dental lamina is a horseshoe-shaped ridge of thickened epithelium overlying the jaws that gives rise to human dentition. Teeth form via the process of odontogenesis. WebPrimary Epithelial Band = ORAL ECTODERM (derived from the Derm layer) *Connective tissue – ectomesinchyme (first sign of tooth formation) Dental Lamina -First sign of tooth development It is formed by proliferation of the primary epithelial band into the underlying ectomesenchyme around the perimeter of both the max. and mand. jaws
