The aim of This study was to identify the skeletal and dentoalveolar
components in Syrian adult subjects whom have an anterior open
bite by comparison with the normal occlusion subjects.
This study showed elongation of upper and lower incisors,
o
f upper molar height and increasing of anterior facial increasing
height (P<0.05) in anterior open bite group compared with natural
occlusion group .
Patients with skeletal open bites are characterized by a long facial morphology characterized by increased anterior facial elevation and posterior rotation of the mandible. Orthodontic treatment of this type of malocclusion is difficult.
This study aimed to compare the dimensions of soft facial tissues
between the open bite and deep bite malocclusion cases, in
patients with sagittally Class I occlusion.
