A buccal exostosis is an exostosis (bone prominence) on the buccal surface (cheek side) of the alveolar ridge of the maxilla or mandible. More commonly seen in the maxilla than the mandible, buccal exostoses are considered to be site specific. [ 2 ]
The buccal space (also termed the buccinator space) is a fascial space of the head and neck (sometimes also termed fascial tissue spaces or tissue spaces). It is a potential space in the cheek, and is paired on each side. The buccal space is superficial to the buccinator muscle and deep to the platysma muscle and the skin.
Generally, the spread of infection is determined by barriers such as muscle, bone and fasciae. Pus moves by the path of least resistance, [5] e.g. the fluid will more readily dissect apart loosely connected tissue planes, such the fascial spaces, than erode through bone or muscles. In the head and neck, potential spaces are primarily defined by ...
Head and neck anatomy Torus Palatinus (torus of the hard palate - roof of the mouth) Mandibular Torus, right side (torus underneath the tongue). An oral torus - also known as: dental torus - is an oral condition in which bony growth occurs in the mouth; there are three locations in which oral tori may appear: the hard palate (torus palatinus), in the lower jaw underneath the tongue (mandibular ...
It is located on the mandibular arch of the mouth, and generally opposes the maxillary first molars and the maxillary 2nd premolar. This arrangement is known as Class I occlusion. There are usually five well-developed cusps on mandibular first molars: two on the buccal, two lingual, and one distal.
For the mandibular arch, this function is provided primarily by the buccal shelf, a region extending laterally from the back or posterior ridges, and by the pear-shaped pad (the most posterior area of keratinized gingival formed by the scaling down of the retro-molar papilla after the extraction of the last molar tooth). Secondary support for ...
Damage to the inferior alveolar bundle is avoided by sectioning the buccal and retromolar cortex of the mandible and the cancellous bone is carefully split. After the mandible has been repositioned, screws or mini-plates can be used to fix the mandible directly. This is instead of fixing it indirectly with intermaxillary fixation (IMF). [18]: 203
Where the two tissue types meet is known as a mucogingival junction. There are three mucogingival junctions: on the facial of the maxilla and on both the facial and lingual of the mandible. The palatal gingiva of the maxilla is continuous with the tissue of the palate, which is bound down to the palatal bones.
