Highlights

The patient’s collaboration regarding the use of extra- oral appliances is a practically impossible task nowadays. With the advent of absolute anchorage using miniimplants, the anchorage problems were solved, favoring greater predictability for orthodontic treatment. The popularization of mini-implants was due not only to its effectiveness in maintaining the anchorage, but also due to its insertion ease, small size and low cost. Despite all the positive aspects, mini-implants may fail, and their main failures are stability within the bone tissue in which they are inserted. Insertion and...

Point of equilibrium
Point of equilibrium

Historically, humanity alternates cycles in its relentless search for explanations in the most diverse spheres, such as arts, philosophy or science. This restlessness, which is inherent to our species, seems to be followed by a certain conflict, because of ingrained beliefs or of habits that we wish to become permanent, be it for protective reasons or for comfort, or simply to establish a point of view.

An interview with Ambrosina Michelotti
An interview with Ambrosina Michelotti

Professor Ambrosina Michelotti is one of the most important researchers in the field of Orthodontics, Temporomandibular Disorders and Orofacial Pain. I’m following her publications since I first read the revision article about the role of Orthodontics in Temporomandibular Disorders, published in 2010 on the Journal of Oral Rehabilitation, which helps to elucidate in a very didactic way the concepts based on scientific evidence that link these two areas. As I am involved on the same field...

Mandibular anterior crowding: normal or pathological?
Mandibular anterior crowding: normal or pathological?

The teeth become very close to each other when they are crowded, but their structures remain individualized and, in this situation, the role of the epithelial rests of Malassez is fundamental to release the EGF. The concept of tensegrity is fundamental to understand the responses of tissues submitted to forces in body movements, including teeth and their stability in this process. The factors of tooth position stability in the arch — or dental tensegrity — should be considered when one...

Correlation between craniofacial growth and upper and lower body heights in subjects with Class I occlusion
Correlation between craniofacial growth and upper and lower body heights in subjects with Class I occlusion

Objective: To correlate skeletal age, standing height, upper and lower body lengths, and selected craniofacial growth features in a sample of growing individuals, and to model craniofacial growth using multivariate regression. Methods: This was a retrospective cross-sectional study with 447 African black boys and girls, between the ages 8 and 16 years, who attended the dental clinic at one hospital. The skeletal maturational age was determined from hand-wrist radiographs using the Greulich...

Impact of malocclusion on the quality of life of children aged 8 to 10 years

Objective: The aim of the present cross-sectional study was to assess the impact of malocclusion on the quality of life of children aged 8 to 10 years attending public elementary schools in Belo Horizonte, State of Minas Gerais, Brazil. Methods: The Brazilian version of the Child Perceptions Questionnaire 8-10 (CPQ8-10) was used to evaluate oral health-related quality of life. The children were examined for the diagnosis of malocclusion using the Dental Aesthetic Index (DAI). The data were...

Additional intraoral radiographs may change the judgment regarding the final position of orthodontic mini-implants
Additional intraoral radiographs may change the judgment regarding the final position of orthodontic mini-implants

Objective: This study aimed to assess if additional vertical bitewing (VBW) and/or occlusal (OC) radiographs may change initial judgment based only on periapical radiograph (PAR) about the final position of orthodontic mini-implants (OMI). Methods: Subjective and objective analyses were performed. Radiographic images of 26 OMI were divided into four groups: PAR, PAR+VBW, PAR+OC and ALL (PAR+VBW+OC). For subjective analysis, five observers were asked to assess if the position of OMI was...

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

Evaluation of the prototype of a new bracket-positioning gauge
Evaluation of the prototype of a new bracket-positioning gauge

Objective: The purposes of this study were to present a prototype of a bracket-positioning gauge, which makes vertical inclination of the instrument difficult, allowing a reduction of vertical bracket positioning error, and to test its accuracy in bracket positioning by groups of individuals with different clinical experience and in specific groups of teeth. Methods: For the testing of the prototype, four groups of six participants each were used: Group 1 was composed of undergraduate...
