The oral vestibule is bounded externally by the lips and the cheek mucosa and internally by the alveolar processes and the teeth.
When the teeth are in occlusion, the vestibule communicates with the oral cavity proper via the intermaxillary commissure behind the last molar teeth.Sep 11, 2015.
Labial Fissure: Slit-like space between the lips; the oral vestibule..
It is a slit-like space between the lips / cheeks,and the teeth & alveolus.
The oral cavity vestibule is separated from the oral cavity proper by the alveolar bone & teeth.
The mucosa covering the alveolus is reflected on to the lips and cheeks, forming a sulcus called as vestibular fornix..
The vestibular lamina (VL) forms as an epithelial outgrowth parallel to the dental lamina (DL) in the oral cavity.
During late development, it opens to create a furrow that divides the dental tissue from the cheeks and lips and is known as the vestibule..
A narrow, natural space between the exteriors of the teeth and the interiors of the lips and cheeks.
The vestibule is bordered along its cranial and caudal aspects by the vestibular fold from where the attached gingiva merges into the mobile mucosa..
The nerve supply comes from the branches of six cranial nerves, namely - the trigeminal nerve, facial nerve, glossopharyngeal nerve, vagus nerve, and the hypoglossal nerve, whereas the blood supply comes from the branches of the external carotid artery and the veins drain into the internal and external jugular veins..
It is divided into two parts by the upper and lower dental arches (formed by the teeth and their bony scaffolding)
The two divisions of the oral cavity are the vestibule and the mouth cavity proper
The horseshoe-shaped vestibule is situated anteriorly
It is the space between the lips/cheeks, and the gums/teeth
The oral vestibule is a small slit-like space between the teeth and inner mucosal lining of the lips and cheeks
The mucosa of the lips and cheeks continues onto the gingiva to form the superior and inferior boundaries of the vestibule

The Vestibule ( vestibulum oris) is a slit-like space, bounded externally by the lips and cheeks; internally by the gums and teeth
It communicates with the surface of the body by the rima or orifice of the mouth
