Assessment of the impact of tongue size in patients with bimaxillary protrusion.

Background: Tongue size, posture and pressure are considered to have significant influences on the positioning of dentoalveolar structures. Based on the equilibrium theory, forward resting posture of the tongue with light force and long duration could have both a horizontal and vertical effect on teeth. Bimaxillary proclination, a malocclusion trait often seen in African descents with multifactorial etiological factors, could well be related to tongue dimensions.
