(20) (2001) reported that patients with unilateral posterior crossbite
chewed more slowly than did the controls, and after treatment their cycle duration was shortened to equal those of control values.
Rapid maxillary expansion (RME) is a widely used treatment in orthodontics that not only provides progress in patients with arch length discrepancies or crossbites
but also decreases nasal resistance that in fact relieves mouth breathers.
Diagnosis and conservative treatment of skeletal Class III malocclusion with anterior crossbite
and asymmetric maxillary crowding.
They were characterized for the presence of canines' key, overjet, overbite and posterior crossbite
There was no statistically significant relationship between the severity of OSA of the studied patients and the observed degrees of overjet (p=0.427), overbite (p=0.861) and buccal or lingual crossbite
Effect of unilateral posterior crossbite
and unilateral cleft lip and palate on vertical mandibular asymmetry.
Various interceptive orthodontic treatment procedures are: Correction of developing Crossbite
(reverse bite of the opposing teeth) can be done using maxillary arch expansion appliance.
The five components of ICON include assessment of aesthetic assessment; upper arch crowding or spacing; crossbite
; incisor openbite or overbite; and buccal segment anteroposterior relationship.
Further, transversely depicted in posterior crossbite
and narrow deep maxillary arch was also present positively in mouth breather, all this correlates with Ricketts and Harvold keystone studies in this field as referred above.
Intraorally bilateral single tooth crossbite
with 55, 65 were present.
To prevent this effect, patients with crossbite
or deviation during closure were excluded.
Nevertheless, many of these OFs presented strong values, such as horizontal overbite (HO) > 4 mm (OA=5.0), open bite (OA = 7.6), crossbite
(OA = 3.8), and vertical overbite (VO) > 4 mm (OA = 3.4), while others presented weaker values, such as Class II (OA = 2.8) and lack of occlusal stability (OA=2.0).
