The anterior mandible is generally defined as the part of the mandible rostral to the mental foramina, and hence, it is also called the interforaminal region). The latter term is widely used in dental implantology, and it was introduced in the early phase of modern implant dentistry reflecting the concept of implant-borne removable, and later fixed, full mandibular prostheses (Almog et al. 2007).
The anterior maxilla is a clinically critical area frequently requiring extensive surgical interventions, e.g., placement of dental implants, surgical removal of impacted or supernumerary teeth, periodontal surgery, endodontic surgery, cyst therapy, and orthognathic surgery. This is particularly true regarding treatment of edentulous or partially dentate patients that were previously rehabilitated with mucosa- or tooth-borne prostheses; however, the focus has shifted to implant-borne reconstructions in the last three decades (Belser et al. 2000; Pjetursson et al. 2007
The floor of the mouth is a horizontally aligned U-shaped space situated in the part of the oral cavity that is located beneath the tongue (La’porte et al. 2011). As such, the floor of the mouth represents the inferior (caudal) anatomical boundary of the oral cavity. The main structures of the floor of the mouth include the mylohyoid muscles, the geniohyoid muscles, the sublingual glands, the deep processes (oral parts) of the submandibular glands, and the lingual mucosa stretching from the inner aspect of the mandible to the body of the tongue.
The palate comprises the hard and the soft palate simultaneously forming the roof of the oral cavity and the floor of the nasal cavity. The U-shaped dental arch provides the anterior and lateral border of the hard palate, while the free margin of the soft palate represents the posterior border of the palate. The internal structures of the hard palate include the palatine processes of the os maxilla (anterior three quarters) and the horizontal plates of the os palatinum (posterior quarter)
The infraorbital region is a component of the midface and can be defined as the anatomical area between the nasal aperture and the zygomatic bone below the inferior rim of the orbit and above the roots of the maxillary canine and premolars. This area contains several clinically important structures including the infraorbital foramen (IOF), the infra-orbital nerve (ION) and artery (IOA), and their various branches to the adjacent anatomical structures.
The oral cavity is an important part of the skull with multiple physiologic functions such as deglutition including biting and mastication, swallowing, phonation, and respiration. Hence, a healthy and functioning oral cavity is a prerequisite for life and well-being. Unique structures of the oral cavity include the teeth, the gingiva, and the tongue that are all highly specialized tissues, in particular for eating and speaking, and, as such, are not found in other parts of the body.
The posterior mandible is usually defined as the part of the mandible posterior to the mental foramen. Hence, the posterior mandible comprises the posterior body of the mandible, the angle, the ascending ramus, the coronoid, and the condylar processes of the mandible.
The vestibule comprises the small external portion of the oral cavity, and it forms a horseshoe-shaped space marking the reflection of the mucous membrane from the lips and cheeks to the gingiva. The boundaries of the vestibule include soft tissues of the lips anteriorly and the cheeks laterally. Labial glands are present in the mucosa and produce fluid that empties through small ducts in the vestibule keeping it moist.
The temporomandibular joint (TMJ) is a synovial joint and the only true joint in the oromaxillofacial region. It is also referred to as mandibular joint or craniomandibular articulation. The TMJ is unique with regard to its rotary (ginglymoid) and translatory (arthrodial) movements during jaw function including mouth opening and closure, mastication, and speech.
The oral cavity (l, oris, mouth) forms the rostral opening of the digestive tract and contributes to critical functions including mastication, vocalization, and respiration. It is divided into a smaller external portion, the vestibule, and a larger internal component, the oral cavity proper. The vestibule forms as a cleft between the lips and cheeks externally and the teeth internally
The parotid gland is characterized as a compound tubuloalveolar gland. It is the largest of the salivary glands that, as a group, also include the submandibular and sublingual glands as well as numerous small glands in the mucosa of the oral cavity. The parotid gland is located in the interval between the sternocleidomastoid muscle and mandible extending from the posterior part of the zygomatic arch to the outer mandibular angle in the vertical direction.
La mandíbula anterior generalmente se define como la parte de la mandíbula rostral a los agujeros mentales y, por lo tanto, también se llama región interforaminal. El último término se usa ampliamente en implantología dental. Otro término utilizado con frecuencia para describir la mandíbula anterior es "sínfisis".
