Maxillary cysts can be odontogenous or nonodontogenous, and are differently invasive for maxillary bones.
A cyst naturally tends to expand continuously and this is one of the main reasons why they must be removed – remove wall to let a new bone grow into the cavity.
Not removing a cyst may lead to the complete loss of teeth concerned or, even worse, to a lower jaw bone fracture.
When there is an included tooth in a maxillary cyst, it can be brought back on dental arch thanks to special techniques.
As any oral injury, cysts have to be examined by a pathologist for the diagnostic histopathology of the specimen.
