maxillary process

n.

A thin plate projecting from the upper border of the lower nasal concha, articulating with the maxilla and partly closing the orifice of the maxillary sinus.

maxillary process

Etymology: L, maxilla, upper jaw, processus

1 the alveolar process of the upper jaw that contains the tooth sockets.

2 the frontal process that extends upward to articulate with the frontal and nasal bones.

3 the palatine process that helps form the hard palate.

4 the zygomatic process, or anterior surface, that articulates with the zygomatic bone.

process (pros´es, prō´ses),

n 1. in anatomy, a marked prominence or projection of a bone.
2. in microanatomy, a protrusion of tissue.
3. in dentistry, a series of operations that convert a wax pattern, such as that of a denture base, into a solid denture base of another material. See also denture curing.

process, alveolar,

n the portion of the maxillae or mandible that forms the dental arch and serves as a bony investment for the teeth. Its cortical covering is continuous with the compact bone of the body of the maxillae or mandible, whereas its trabecular portion is continuous with the spongy bone of the body of the jaws. See also ridge, alveolar.

process, condyloid

n a projection of the mandible arising on the posterosuperior aspect of the mandibular ramus. It consists of a neck and an elliptically shaped head or condyle that enters into the formation of the temporomandibular joint in conjunction with the articular disk and the glenoid fossa of the temporal bone.

process, coronoid,

n the thin, triangular, rounded eminence originating from the anterosuperior surface of the ramus of the mandible. Provides insertion for the temporal muscle.

process, dehiscence of alveolar,

n See dehiscence.

process, fenestration of alveolar

n a circumscribed opening, located in the cortical plate over the root, that does not communicate with the crestal margin.

process, hamular

n (pterygoid process) the pterygoid process of the sphenoid bone; appears as a vertical projection distal to the maxillary tuberosity.

process, horizontal resorptive,

n the pattern of bone resorption, occurring with periodontal disease, in which the resultant level of bone is more or less flat or level in nature.

process, inferior articular,

n the natural growth of bone that convexly projects in a forward lateral direction from the lumbar vertebrae.

process, lateral nasal,

n the triangular cartilage that spans the bridge of the nose and is attached below the nasal bone and the front of the maxilla.

process, mandibular,

n the stage of embryonic development during which two sections of the first branchial arch come together to create the mandibular arch.

process, maxillary,

n the stage of embryonic development during which a prominence off of the first branchial arch unites with the corresponding median nasal prominence to form the upper jaw.

process, medial nasal,

n a protrusion of tissue located midline to the olfactory pits during embryonic development from which the tip of the nose and philtrum of the lip develop.

process, neck of condyloid,

n the part of the condyloid process that connects the condyle to the main part of the ramus.

process, odontoblastic

n a structure of the tooth formed during dentogenesis. It becomes encased by predentin that eventually calcifies.

process, pterygoid

n See process, hamular.

process, Tomes',

n a narrow extension of the ameloblast from which the enamel matrix is secreted.

maxillary

emanating from or pertaining to the maxilla.

maxillary collapse

includes failure of the maxilla to grow, as in achondroplastic dwarfism, or atrophy due to turbinate atrophy, as in atrophic rhinitis. The result is a dishing or depression of the face.

maxillary cyst

a cyst that occurs in young horses and causes sufficient distortion of the bone as to obstruct the nasal passage.

maxillary myositis

a localized myositis of unknown origin which occurs in young horses. It causes inability to eat or to suck the mare. The muscles of the cheeks are hard.

maxillary process

an embryonic fold which develops from the first visceral arch and expands to produce the rostral bones of the upper jaw.

maxillary sinusitis

infection in the maxillary sinus, often from an infected tooth. Causes local facial swelling and nasal discharge. See also malar abscess.

maxillary swelling

a unilateral swelling which is usually an indication of an osteomyelitis, as in actinomycosis of cattle, tooth-root abscess of dogs or sinusitis in horses. Bilateral swellings are characteristic of osteodystrophia fibrosa in dogs and horses.
