First molar cross-bite is more closely associated with a reverse chewing cycle than anterior or pre-molar cross-bite during mastication.

Functional changes after early treatment of unilateral posterior cross-bite associated with mandibular shift: a systematic review.

The objective of this systematic review was to investigate whether oral functional asymmetry in children treated for unilateral functional posterior cross-bite disappears after orthodontic treatment with a resulting normalisation of oral functions. A literature search was carried out using PubMed, Web of Science and the Cochrane Library to locate longitudinal studies reporting on clinical oral ...

Effects of cross-sectional area on human bite studied with raw carrot and surimi gel.

The effects of the cross-sectional area of food samples on bite force with molar teeth were investigated using raw carrots and surimi gels. We evaluated human bite force for food samples with different sizes between the upper and lower molars using a multiple-point sheet sensor and electromyography (EMG). The bite force curve and EMG clearly showed textural characteristics of the carrot and gel...

Rapid correction of a simple one-tooth anterior cross bite due to an over-retained primary incisor: clinical report.

Where a permanent anterior tooth cross bite results from over-retention o[ z~ primary incisor, a rapid correction method may prove successlrul. When the over-retained primary incisor is extracted, the permanent successor in cross bite is tipped into the extraction site, correcting the cross bite. Moyers defines a simple anterior tooth cross bite as a dental malocclusion resulting from the abnor...

Stresses in mandibular cortical bone during mastication: biomechanical considerations using a three-dimensional finite element method.

This study investigated biomechanical aspects of the action of the biting force during mastication upon the mandibular bone in the lower first molar area. A three-dimensional (3D) finite element model (FEM) consisting of the tooth, periodontal ligament (PDL), alveolar bone, and cortical bone corresponding to the lower first molar area based on computed tomogram (CT) images was constructed. The ...
