Glossary

Words, defined plainly.

Educational definitions for the terms that appear across the work. Neutral, original, and as honest as we can make them.

Orthotropics

The study of how the face grows and how everyday posture shapes that growth. An educational framework concerned with biology, observation, and prevention as premise.

Mewing

The informal name given by online communities to the practice of holding the tongue against the roof of the mouth as a resting posture. Named for the family that has long taught about oral posture.

Oral Rest Posture

The default position of the tongue, lips, and teeth when the mouth is not actively doing anything else. The posture a face spends most of its day in.

Nasal Breathing

Drawing air in and out through the nose. Considered, in the educational framework of orthotropics, the biologically intended route of respiration.

Malocclusion

A descriptive term for a relationship between upper and lower teeth that departs from a textbook arrangement. Treated, in orthotropics, as a sign worth understanding rather than a verdict.

Craniofacial Growth

The developmental processes by which the skull and face take shape over a lifetime. A lifelong, load-responsive process.

The Airway

The passage through which air travels into and out of the lungs. Its size and shape are closely related to the structures of the face and jaw.

Prevention

The orthotropics premise: that the most useful questions about facial growth are about supporting the conditions for healthy growth, rather than about doing something later.
