Maxillary tuberosity
Maxillary Tuberosity
The Maxillary Tuberosity is a rounded area located at the posterior end of the upper jaw, or maxilla. It is found behind the last molar tooth in the upper jaw. The maxillary tuberosity is covered by the mucous membrane of the mouth.
Etymology[edit | edit source]
The term "Maxillary Tuberosity" is derived from the Latin words "maxilla" meaning jaw, and "tuberositas" meaning a small rounded projection or protuberance.
Anatomy[edit | edit source]
The maxillary tuberosity is a bony protuberance on the maxilla located posterior to the third molar. It is covered by a mucous membrane. The maxillary tuberosity contains the posterior superior alveolar nerve and blood vessels that supply the maxillary molars and the sinus membrane.
Clinical Significance[edit | edit source]
The maxillary tuberosity is of clinical significance in dentistry. It is often involved in procedures such as tooth extraction, dental implant placement, and maxillary sinus lift procedure. The size and shape of the maxillary tuberosity can affect the difficulty of these procedures.
