Anatomy The maxilla is centrally located within the skull and makes up the center of the face. 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 Maxilla 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 The maxillary nerve is the second of three branches of the trigeminal nerve. It arises between the trigeminal's ophthalmic and mandibular divisions in a region called the trigeminal ganglion, a cluster of nerves involved in relaying sensory information to the brain as well as chewing motor function. 2 ï»

The two maxilla or maxillary bones (maxillae, plural) form the upper jaw (L., mala, jaw). Each maxilla has four processes (frontal, zygomatic, alveolar, and palatine) and helps form the orbit, roof of the mouth, and the lateral walls of the nasal cavity. Body - central portion of maxilla. [Anterior view/ Lateral view The maxilla is the upper dental arch that contains the maxillary alveolar process, the maxillary teeth and the maxillary sinuses. It sits on either side of the nasal cavity and below the orbits. There are characteristic landmarks both in the anterior and posterior segments of the maxilla that can be observed on maxillary periapicals anatomy_maxillary_bone 2/3 Anatomy Maxillary Bone [Book] Anatomy Maxillary Bone Bone Augmentation by Anatomical Region-Zvi Artzi 2020-05-15 Comprehensively describes bone augmentation techniques and their application to the different anatomical regions of the upper and lower jaws.

The Body (corpus maxillæ). —The body is somewhat pyramidal in shape, and contains a large cavity, the maxillary sinus (antrum of Highmore). It has four surfaces—an anterior, a posterior or infratemporal, a superior or orbital, and a medial or nasal The maxillary sinus (latin: sinus maxillaris) is the largest of the sinuses, filling the body of the maxilla.It is somewhat pyramidal in shape. The bilateral maxillary sinuses are located lateral to the nasal cavities and under the orbits.. Each maxillary sinus opens into the middle nasal meatus of the nasal cavity with an opening called the maxillary hiatus. The maxilla (plural: maxillae / m æ k ˈ s ɪ l iː /) in vertebrates is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine.This is similar to the mandible (lower jaw.

The upper jaw (maxilla) holds the upper teeth, shapes the middle of the face, and supports the nose. A good bite (occlusion) means that the upper and lower teeth are straight and fit together properly.

Zygomatic process. Frontal process. Palatine process Upper Jaw Maxilla. The upper jaw (maxilla) is an irregular bone formed from the right and left maxillary bones, which unite along the midline of the face (see figure 2-2). It joins in the palate (roof of the mouth) at the intermaxillary suture or at the median palatal suture. The maxilla is considered the key to the architecture of the face

Maxillary Second Molar - root formation may be different from first molar - usually three canals - access similar to maxillary second molar (blunted triangular - outline) - always look for four canals - more variability of anatomy in second and third molars compared to first molar. Mandibular first molar - has two well formed root Problems can result in the maxillary tuberosity during tooth extractions. The tuberosity is a major landmark in the upper jaw, on both sides of the top dental arch.A person will find this landmark situated just behind and above the third molar tooth, which also is known as a wisdom tooth. The posterior superior alveolar nerves usually pierce the back surface of the maxillary tuberosity Maxillary First Molar.
