Furthermore, vestibular lamina will subsequently hollow and forms the oral vestibule between the alveolar portion of the jaws and the lips and cheeks. Recent studies have found that both the dental lamina and vestibular laminae jointly give rise to the large tooth primordia in the cheek region of the maxilla.
A plane parallel to the surface of a tooth. For example, if a drill bur would be inserted into a tooth from any side (proximal, vestibular, oral), the depth of the hole is defined from the axial wall of the hole (from the long axis walls (vertical surfaces bounding the tooth)). [1] Buccal
A cusp is an elevation on an occlusal surface of posterior teeth and canines. It contributes to a significant portion of the tooth's surface. Canines have one cusp. Maxillary premolars and the mandibular first premolars usually have two cusps. Mandibular second premolars frequently have three cusps--- one buccal and two lingual.
The most acknowledged theory for supernumerary teeth is hyperactivity of dental lamina. [6] On completion of the dentition, the dental lamina is usually destroyed and reabsorbed, but when remnants fail to resorb, it can continue to proliferate abnormally. This abnormal proliferation can form the extra tooth bud leading to supernumerary teeth ...
As a tooth is forming, a force can move the tooth from its original position, leaving the rest of the tooth to form at an abnormal angle. Cysts or tumors adjacent to a tooth bud are forces known to cause dilaceration, as are primary (baby) teeth pushed upward by trauma into the gingiva where it moves the tooth bud of the permanent tooth.
German illustration (c. 1910) depicting interior of jawbones, with nerves, veins, and arteries leading to teeth—and thus the alveolar areaOn the maxilla, the alveolar process is a ridge on the inferior surface, making up the thickest part of the bone.

Anatomy of the mouth. Floor of the mouth with lingual frenum and sublingual fold. The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3]
