PURPOSE The purpose of this longitudinal study was to assess the relationship between nonnutritive sucking habits and anterior open bite in 305 4- to 5-year-old children attending state schools in the city of Recife, Brazil. METHODS The data were collected by interviewing the children's mothers or guardians and through clinical examinations carried out by 1 calibrated examiner (K = 1). Bivari...

INTRODUCTION The aim of this prospective clinical study was to cephalometrically investigate the dentoalveolar and skeletal changes produced by a removable appliance with palatal crib associated with high-pull chincup therapy in children with Angle Class I anterior open-bite malocclusions. METHODS Thirty children with initial mean age of 8.61 years and mean anterior open bite of 4.01 mm were ...

OBJECTIVE To assess the position and movements of the hyoid bone during deglutition in patients with open bite. METHODS Thirty-six subjects were divided into 2 groups according to the presence of anterior open bite. The open bite group (OBG) and control group each comprised 18 patients with a mean overbite of -4.9 ± 1.9 mm and 1.9 ± 0.7 mm. The position of the hyoid bone during the 4 stages o...

Open bite is a malocclusion that occurs in the vertical plane, characterized by lack of vertical overlap between the maxillary and Mandibular dentition. The anterior open bites particularly skeletal open bites are called as “stigmata of malocclusion”. The varied etiological characterstic features of openbite are discussed in this article. Openbites are easy to diagnose but difficult to retain. ...

Anterior open bite (AOB) is a term used if there is localized absence of occlusion anteriorly when the remaining teeth are in occlusion; it is commonly one of the main symptoms of an overall dentofacial deformity. Diagnosis, treatment, and retention can be difficult because this malocclusion has numerous correlated etiologic factors. Clinically, it is grouped into 2 main categories: dental or a...
