At the lower part of the infratemporal surface of the maxilla is a rounded eminence, the maxillary tuberosity, especially prominent after the growth of the wisdom tooth; it is rough on its lateral side for articulation with the pyramidal process of the palatine bone and in some cases articulates with the lateral pterygoid plate of the sphenoid.
The maxillary tuberosity is located on the lower part of the infratemporal surface of maxilla. This area is a rounded prominence that becomes especially noticeable after the growth of the wisdom teeth.
The maxillary tuberosity or maxillary eminence has several small openings called alveolar foramina that lead into the alveolar canals. These canals transmit the posterior superior alveolar nerves and posterior superior alveolar arteries and veins to the upper teeth.
It descends on the maxillary tuberosity and penetrates the inferior alveolar canal on the infratemporal maxillary surface, providing innervation to the molars and posterior wall of the maxillary sinus as well as giving off branches that join the MSA and ASA to form the alveolar plexus.
The lower portion of the maxilla is connected to the upper teeth through the alveolar process. The roots of the teeth form grooves that extend up the anterior portion of the maxilla. The alveolar process extends posteriorly below the maxillary sinuses and ends in the maxillary tuberosity.
The maxilla, also known as the upper jaw, is a vital viscerocranium structure of the skull. It is involved in the formation of the orbit, nose and palate, holds the upper teeth and plays an important role for mastication and communication.
Maxillary tuberosity – The maxillary tuberosity is the rounded end of the alveolar process of the maxilla. This radiopaque structure appears bilaterally on maxillary molar periapical images and often on maxillary premolar periapical images and molar bitewings.
Key Features: Zygomatic, frontal, alveolar, and palatine processes, body, canine fossa, maxillary tuberosity, and anterior lacrimal crest. Articulates With: Opposite maxilla, ethmoid, frontal, lacrimal, palatine, nasal, and zygomatic bones, vomer, and inferior nasal concha.
The maxillary tuberosity (MT) is a bilateral anatomical structure that corresponds to the distal and inferior border of the infratemporal surface of the upper maxilla, where normally the alveoli of the third molars are located, with its posterior and superior limits being the pterygomaxillary fissure and the floor of the maxillary sinus ...
The maxillary tuberosity is a rounded projection of a compact bone that extends posteriorly from the alveolar crest, continuing the structure of the maxillary bone. It is mesially bounded by the last erupted molar and maxillary sinus, while distally it is bounded by the pyramidal process of the palatine bone and pterygopalatine fissure [6].
