Understanding Orthognathic Anatomy and Problems

A jaw that's too small, too large, or crooked can cause problems with chewing, speaking, breathing, and even sleeping. The shape of your jaws also affects the way your face looks. This sheet helps you understand how the teeth and jaws work. It also describes common jaw problems that may need treatment.

How Bones and Teeth Shape the Face

Bones are the framework for the face. The size and position of facial bones determine how well the teeth fit together. Together, the positions of the jaws and teeth affect chewing, speaking, and the working of the jaw joint. The jaws also hold and support soft tissues, such as the muscles, lips, and tongue. And of course the jaws and teeth are factors in the face's shape and appearance.

How the Jaws Work

The lower jaw holds the tongue, which moves freely as you speak and eat. The upper jaw shapes the floor of the nasal cavity, allowing normal airflow. Normally, muscles are evenly developed on both sides of the face.

Orthognathic Anatomy and Problems, Understanding

Common Problems

Some common jaw alignment problems are described below. It's also common to have a combination of these problems.

  • Lower jaw too far back: When the lower jaw is too far back (retrognathia), biting can be difficult. The chin appears weak or receding.
  • Lower jaw too far forward: A lower jaw that is too far forward (prognathia) causes the chin to protrude. Lower teeth may jut outward to overlap the upper teeth.
  • Open bite (teeth don't meet): An open bite is often due to a long upper jaw. This can cause a "gummy smile." Or the problem may be that the rear of the lower jaw is too short. An open bite can make it impossible to close the lips.
  • Asymmetry (jaws are uneven): Uneven jaws are larger or smaller on one side than on the other. Or one side may be too far forward or back. The face may look off-center or crooked.

When Jaws Are Not Aligned

Poorly aligned jaws can result in a variety of problems, including:

  • Chewing problems: You may find it difficult to bite into a sandwich or an apple, or difficult to keep food in your mouth as you chew. The TMJs may be stiff or painful.
  • Speech problems: It may be difficult to make certain sounds or to speak clearly.
  • Breathing problems: If the airway is narrow or blocked, breathing may be noisy or difficult. You may have sleep apnea (breathing that stops during sleep).
  • Problems with appearance: You may be unhappy with the way you look. This can make you self-conscious and may affect your confidence.
