maxilla

 [mak-sil´ah] (L.)
one of two identical bones that form the upper jaw. The maxillae meet in the midline of the face and often are considered as one bone. They have been described as the architectural key of the face because all bones of the face except the mandible touch them. Together the maxillae form the floor of the orbit for each eye, the sides and lower walls of the nasal cavities, and the hard palate. The lower border of the maxilla supports the upper teeth. Each maxilla contains an air space called the maxillary sinus.

maxilla

One of a pair of joined facial bones that form the upper jaw, the hard palate, part of the wall of the cavity of the nose and part of the floor of each eye socket. The maxillae bear the upper teeth and each contains a cavity called the maxillary antrum or sinus.

maxilla

  1. (in vertebrates) one of a pair of joined bones forming the upper jaw, carrying all teeth except the incisors. The term is loosely used to denote the whole of the upper jaw.
  2. (in arthropods) that part of the mouthparts lying behind the jaws. See LABRUM and LABIUM.

Maxilla

The bone of the upper jaw which serves as a foundation of the face and supports the orbits.

Endoscopy, which decreases the rate of morbidity during and after such operations, can also be used for the treatment of the DCs in the maxilla (7).
More forward movement was detected twice at the A point and maxilla in the groups involving the Alt-RAMEC protocol, except in two studies, than in the Alt-RAMEC protocol applied to the group.
Skeletal class I was taken as ANB = 2 +- 2 degree when maxilla and mandible were in linear relation, skeletal class II was taken as ANB > 4 degree when maxilla and mandible were in distal relation and skeletal class III was taken as ANB 0.05 which shows that there are no statistically significant differences obtained by this study and we fail to reject the null hypothesis.(See table 1)

Advanced radiographic examination of CT was done, and axial section shows hypodense area in the maxilla extending anterio-posteriorly on the right side with buccolingual cortical expansion with a breach in the buccal cortical plate in the anterior part along with an impacted tooth as hyperdense area and involvement of right maxillary sinus was seen [Figure 5].
