There was a significant association between posterior cross bite
and adenoid hypertrophy with otitis media.
These differences include adenoidal face, narrower maxilla, deeper palatal height, retrusive mandible, deficient chin, and long lower face, cross bites
, increased overjet, and oral breathing.1-3,5,7-12 A study contributed those differences to the long-term changes in the position of the head, mandible, and tongue in order to maintain airway adequacy during sleep.2

Although the index DAI seems to be easier to use, it does not evaluate some occlusal characteristics, such as: cross bite
, deep overbite and deviation of medium line (22).

Both thumb sucking and pacifiers can cause cross bite
, a condition in which the upper teeth are behind the lower teeth instead of in front of them.
Patients with an open bite, cross bite
, presence of caries or restored teeth were excluded.
Results from patients who have already received Propel have been exceptional in a range of cases including spacing, crowding, open bite, cross bite
, and more.
Many dental development problems can be headed off in the mixed dentition; for example, anterior cross bites
. In-time removal of a decidu- ous tooth could prevent a cross bite
, but once the permanent upper incisor is caught on the lin- gual of the lower incisors, treatment is needed.
A little-known fact is that bottle feeding and frequent use of pacifiers causes dental malocclusions and cross bite
(followed by large orthodontist's bills later in life), while breast-feeding does not.
Linder-Aronson1 (1979) associated characteristics such as narrow maxilla, proclined maxillary and mandibular incisors, and a tendency toward posterior cross bite
and anterior open bite with mouth breathing.
In occlusion, he had a unilateral posterior cross bite
