Reverse chewing patterns in patients with bilateral posterior crossbite are related to the occlusal features of the malocclusion.

Background: Bilateral posterior crossbite (BPXB) is a severe malocclusion associated with maxillary hypoplasia. BPXB may involve the same or a different number of teeth between the sides.

Objectives: To evaluate the masticatory function in BPXB and the association between the masticatory alterations and the occlusal features of BPXB.

Functional treatment of bilateral posterior crossbite improves mandibular kinematics during chewing.

Objectives: To evaluate the effects of treatment of bilateral posterior crossbite (BPXB) on mandibular kinematics by the percentage of reverse chewing cycles (RCCs) during soft and hard bolus chewing before and after the correction of the malocclusion with function-generating bite (FGB).

Materials And Methods: This prospective study included 71 subjects: 19 patients with occlusally symmetric BPXB (M = 9; F = 10; mean age 9.3 ± 2.

Effects of Contact Sports on Temporomandibular Disorders: An Observational Study.

The study investigated the prevalence of temporomandibular disorders in 100 competitive athletes in contact sports, equally grouped by the practiced game: Soccer (SoG), Rugby (RG), American Football (AFG), Boxing (BoG), Basketball (BaG), compared to a randomly control group of 20 non-athletes (CG). Symptoms and signs were examined according to the standardized Diagnostic Criteria for Temporomandibular Disorders through a questionnaire and clinical evaluation. Arthralgia showed significant differences between RG and CG and between AFG and CG (p < 0.

Evaluation of masticatory function in patients with cleft lip and/or palate.

The aim of this study was to evaluate the masticatory pattern in children with cleft lip and/or palate (CL/P) through investigation of the prevalence of reverse sequencing chewing cycles. The study group included 18 patients with CL/P (mean age: 7.4 yr, SD: 1.

Thoracic-lumbar-sacral spine sagittal alignment and cranio-mandibular morphology in adolescents.

Purpose: The relationship between thoracic-lumbar-sacral spine sagittal alignment and craniofacial morphology is still controversial. Evidence-based results are difficult to obtain and scientific studies are inhomogeneous. The aim of this study was to investigate the difference of thoracic-lumbar-sacral spine posture and cephalometric values comparing two groups of subjects with different cranial structure in the sagittal plane.

Effects of therapy on masseter activity and chewing kinematics in patients with unilateral posterior crossbite.

Objective: To describe the effects of therapy on masseter activity and chewing kinematic in patients with unilateral posterior crossbite (UPC).

Design: Fifty children (age: mean ± SD: 9.1 ± 2.

Changes in electric activity of masseter and anterior temporalis muscles before and after orthognathic surgery in skeletal class III patients.

Objective: The purpose of this study was to evaluate, through clinical and electromyographic (EMG) assessments, the electric activity of masseter muscle and anterior temporalis muscles during clenching, before and after orthodontic treatment and mandibular setback, with or without LeFort I osteotomy, for correction of mandibular excess.

Study Design: Seventeen adult patients (10 males, 7 females, mean age: 22.5 ± 2.
