Post-traumatic anterior open bite can occur as a result of broken balance among the masticatory muscles. The superior hyoid muscle group retracts the mandible downward and contributes to the anterior open bite. Denervation of the digastric muscle by injection of botulinum toxin type A (BTX-A) can reduce the power of the digastric muscle and help to resolve the post-traumatic anterior open bite....

Multiple treatment strategies aimed at different etiologies of anterior open bite have been proposed. However, the tendency toward relapse after conventional or surgical orthodon...

Control of the height of posterior dentoalveolar regions is of great importance for the correction of skeletal open bite. Traditionally, second premolar extraction facilitates the closure of open bite by inducing a counterclockwise mandibular rotation without molar intrusion. This article reports treatment for a 24-year six-month-old female patient with an open bite and large anterior facial he...

OBJECTIVE To analyze 6 different types of visible anterior occlusion, exclusive of extraoral facial features, in terms of their esthetic appeal, as perceived by 91 randomly selected adult laypersons with different levels of education in Lima, Peru. METHODS Photographic images of 3 examples of each occlusion type (open bite [OB], deep bite [DB], crossbite [CB], end-to-end bite [EE], crowded bi...
