Dental Plexus Maxillary

**Dental plexus of the upper jaw** (plexus maxillaris dentalis major) is the structure of the neurovascular bundle in the canal of the upper jaw. It is a branch of the pterygopalatine plexus (pans ciliaris), which gives off the radial dental nerve (nervus dentoalveolarius radicis). Located above the greater palatine foramen and along the canal of the first superior molar

The dental plexus is a set of lymphatic vessels developing in the intermaxillary space of both jaws with their intersection by the innervation of the upper type VI tooth and supplying nearby areas of the gums and temporomandibular joint. In addition to the tooth, the plexus has a large vascular vein and nerves. At the same time, it is not attached to the tooth, but is woven into the surrounding tissues, forming “plexuses” inside the layers listed above. The branching area of ​​the plexus is called sublingual, or submandibular submucosal tissue. Part of the dental plexus may also pass along the course of the inferior alveolar nerve to the neck, where the main connection of lymphatic and venous vessels occurs. On the other side of the carious cavity, the plexus can attach directly to the surface of the tooth. The further distribution of the branches of the dental plexus in the layer of the deep cervical wall is unknown, but the zones, with the exception of the area around the maxillary molars, are thought to be devoid of lymphocyte accumulation. In addition, the bone tissues of the jaws and teeth have a high specific protective ability, therefore the formation of primary barrier cells that prevent infection from penetrating into the deep layers of tissue and ensures the production of natural antibacterial components by human mucous membranes.
