Editing Maxilla (section)

==Clinical Significance==
The maxilla is of paramount importance in several dental specialties:

===Sinus Proximity===
The roots of the maxillary [[molars]] and [[premolars]] are often in close proximity to the floor of the '''[[maxillary sinus]]'''. 
* '''[[Oroantral communication]]''': A potential complication after extraction where a hole is created between the mouth and the sinus.
* '''[[Sinus lift]]''': A surgical procedure to increase bone volume in the posterior maxilla for [[dental implant]] placement.

===Le Fort Fractures===
In oral and maxillofacial surgery, the maxilla is the site of classic "Le Fort" midface fractures:
* '''Le Fort I''': Horizontal fracture above the alveolar process (floating palate).
* '''Le Fort II''': Pyramidal fracture involving the nasal bones and orbital floor.
* '''Le Fort III''': Complete craniofacial dysjunction.

===Orthodontics===
The maxilla can be expanded using a '''[[Rapid Palatal Expander]] (RPE)''' by opening the mid-palatal suture, typically in growing patients.
