2024-2025- KIM ORAL BIOLOGY-DEVELOPMENT OF MAXILLA

Maxilla

One of two identical bones that form the upper jaw and support the upper teeth, containing the maxillary sinus.

Maxillary sinus

A large pyramidal cavity within the body of the maxilla, important for various functions including air exchange.

Ossification

The process of bone formation; in the case of the maxilla, it occurs in membrane and begins with the development of the pre-maxilla.

Zygomatic process

A rough triangular eminence on the maxilla that articulates with the zygomatic bone.

Inferior orbital fissure

A fissure associated with the maxilla that plays a role in the entry and exit of vessels and nerves.

Palatine process

Part of the maxilla that forms the floor of the nose and the roof of the mouth.

Alveolar process

The thickest and most spongy part of the maxilla, containing the tooth sockets for upper dentition.

Intermaxillary suture

The suture between the two maxillae of the upper jawbone.

Growth of maxilla

Occurs through bone remodeling, sutural growth, and the influence of surrounding structures like the nasal septum.

Maxillary nerve

A sensory nerve that branches from the trigeminal nerve and supplies sensation to the maxillary area.

What bones form the upper jaw?

The upper jaw is formed by two identical bones called the maxilla.

What is contained within the maxilla?

The maxilla contains the upper teeth and the maxillary sinus.

What is the significance of the maxillary sinus?

The maxillary sinus is important for air exchange and plays a role in resonance.

How does ossification occur in the maxilla?

Ossification in the maxilla occurs in membrane and begins with the development of the pre-maxilla.

What is the zygomatic process?

The zygomatic process is a rough triangular eminence on the maxilla that articulates with the zygomatic bone.

What is the function of the inferior orbital fissure?

The inferior orbital fissure allows for the entry and exit of vessels and nerves associated with the maxilla.

What does the palatine process form?

The palatine process of the maxilla forms the floor of the nose and the roof of the mouth.

What is the alveolar process?

The alveolar process is the thickest and most spongy part of the maxilla, containing sockets for upper teeth.

What is the intermaxillary suture?

The intermaxillary suture is the suture between the two maxillae of the upper jawbone.

How does the growth of the maxilla occur?

The growth of the maxilla occurs through bone remodeling, sutural growth, and influence of surrounding structures.

What is the structure of the maxilla?

The maxilla is a paired bone that consists of a body and four processes: frontal, zygomatic, palatine, and alveolar.

Where is the maxillary sinus located?

The maxillary sinus is located within the maxilla, adjacent to the nasal cavity.

What role does the zygomatic bone play?

The zygomatic bone articulates with the maxilla to form the cheek area of the face.

What is the importance of the alveolar process?

The alveolar process supports the upper teeth and is critical for dental anchorage.

How does the maxilla interact with the nasal cavity?

The maxilla forms part of the floor of the nasal cavity and contains the maxillary sinus.

What is a common condition affecting the maxillary sinus?

Sinusitis, which is inflammation of the sinus lining, is a common condition affecting the maxillary sinus.

Which nerve provides sensation to the maxillary area?

The maxillary nerve, a branch of the trigeminal nerve, provides sensation to the maxillary region.

What is the relationship between the maxilla and the mandible?

The maxilla is stationary, while the mandible is a movable bone, allowing for chewing and speaking.

How does age affect the maxilla's structure?

As people age, resorption of bone can occur in the maxilla, affecting its density and structure.

What role do the sutures play in maxilla growth?

Sutures between the maxilla and surrounding bones allow for growth and development during childhood.
