Influence of the palatal plane cant and skeletal patterns in the hard palate thickness?

Introduction: The aim of the present study was to evaluate the thickness of the hard palate at the different angles formed by the palatal plane and the Frankfort horizontal line using computed tomography in patients with different facial patterns for planning the installation of MARPE.

Materials And Methods: The measurements were analysed in the hard palate of 106 patients. Four regions were selected passing through the mesial face, tangent at the level of the cemento-enamel junction of the premolars and molars.

Evaluation of anteroposterior and vertical stability 25 years after Angle class II division 1 treatment with cervical headgear.

Purpose: The goal was to investigate long-term (minimum 20 years) skeletal and dental changes in Angle class II division 1 patients treated with full-fixed orthodontic appliances and cervical pull headgear.

Methods: A longitudinal retrospective study was performed with 20 orthodontic patients, who were treated exclusively by one experienced clinician and whose treatment had been completed a minimum of 20 years ago. Former patients who had been treated from the mid-1970s to the early 1990s were actively sought.

Perception of facial profile attractiveness of a brown subject displaying different degrees of lip projection or retrusion, in the city of Salvador/Bahia.

Introduction: The attractiveness and facial aesthetics are commonly defined by the media in modern society and the number of patients seeking for changes in the facial appearance is progressively increasing. Augmented face convexity is believed to be non aesthetic and among the treatments available for its correction, the extraction of premolars followed by anterior teeth retraction produces a significant effect. However, it is questionable whether the procedure is reasonable in brown and black patients, since dental protrusion is considered a common morphological feature in these groups.

Digital models: How can dental arch form be verified chairside?

Introduction: Plaster dental casts are routinely used during clinical practice to access maxillary dental arch form and assist on fabrication of individualized orthodontic archwires. Recently introduced, digital model technology may offer a limitation for the obtainment of a dental physical record. In this context, a tool for dental arch form assessment for chairside use is necessary when employing digital models.

Unilateral impaction of a maxillary first molar treated in the transitional dentition.

The purpose of this report was to present the case of a nine-year-old patient with unilateral impaction of the permanent maxillary right first molar treated early using a simple and effective fixed appliance. The proposed intervention involved the construction of a fixed palatal arch with a soldered wire extending distally to the impacted permanent first molar. A button was bonded to the occlusal surface of the molar, which was to be used as a leverage point for engaging chain elastics to produce distal movement to disimpact and allow complete eruption of the molar.
