The prevalence of malocclusion among Brazilian preschoolers, associated with the Brazilian macro-regions and gender of preschoolers, was 63.2%, that is, these individuals had at least one of the occlusal problems evaluated (canines' key, overjet, overbite or anterior crossbite
The term anterior crossbite
is commonly used when only one or 2 incisors are involved.
Skeletal class III malocclusion often manifested as anterior crossbite
or arch crossbite, compensatory lip of the upper anterior teeth and compensatory tongue of the lower anterior teeth, mesial occlusion of molar, soft tissue profile for concave type, hypoplasia of middle-face 1/3, lower lip protruding (Liou, 2005; Akbari et al, 2016; Cabrita et al, 2017).
, who evaluated masticatory muscle activity in patients with unilateral cleft lip and palate and anterior crossbite
. The examined group included 29 individuals with CLP ranging in age from 11 to 21 years.
Maxillary first premolars would be extracted for anterior retraction, and the anterior crossbite
would be corrected with a mandibular setback.
It works brilliantly on broad range of crowding, spacing, open bite, deep bite, narrow arches, posterior crossbite, anterior crossbite
, extraction among a few to name.
Before the start of the orthodontic treatment, lower reflex-releasing splint was fabricated which will also help correct the anterior crossbite

The variables that were evaluated in the calibration process were the following: incisor alignment, Angle's classification of malocclusion, posterior and anterior crossbite
, overjet, overbite, anterior open bite, and maxillary midline diastema.
Scissor bite and anterior crossbite
were not registered in any of the examined cases, while posterior crossbite was found to be higher in the study group (23.3%) compared to the control (6.7%) with no statistically significant difference (p=0.063).
