Objective: The aim of this study was to compare the efficiency of two protocols for maxillary molar intrusion with two or three mini-implants. Methods: Twenty five maxillary first molars extruded for loss of their antagonists in adult subjects were selected. The sample was divided into two groups, according to the intrusion protocol with two or three mini-implants. Group 1 consisted of 15 molars that were intruded by two mini-implants. Group 2 consisted of 10 molars intruded by three...

Esse artigo descreve o caso clínico de um paciente com 27 anos de idade, previamente tratado com exodontias dos primeiros pré-molares superiores. O paciente apresentava padrão esquelético de classe III, relação entre caninos de classe III, mordida cruzada anterior e perfil côncavo. Como o paciente recusou-se a ser submetido a um tratamento ortodôntico-cirúrgico combinado, foi utilizada uma miniplaca no lado direito inferior, após as exodontias dos primeiros pré-molares inferiores,...

It is not new that Brazilian Orthodontics is praised overseas due to excellent clinical results presented by Brazilian speakers worldwide. What once were intermittent waves breaking in solitude, are now waves that break elsewhere: from Pororoca at Oiapoque to Chuí at Rio Grande; from Maresias in São Paulo to Pipeline in Hawaii. Recently, at the American Association of Orthodontics (AAO) annual session held in Orlando, USA, Brazilian speakers stood out. Jorge Faber’s speech reminded us of...

AUTOCLAVE AND GLUTARALDEHYDE: EFFECTIVE METHODS IN DECONTAMINATION OF ORTHODONTIC WIRE MARKERS Despite the advances in Orthodontics regarding orthodontic brackets, wire bends are essential to obtain an excellent occlusion. When bending wires, it is necessary to mark them. The available options are pencil marker for overhead projector (fades out in contact with saliva), individual markers or orthodontic dermatograph pencils. When a dermatograph pencil is chosen, the question of how to...

Gingival recession has direct causes and predisposing factors. Orthodontic treatment is able to prevent recession and even contribute to its treatment, with or without periodontal approach, depending on the type and severity of gingival tissue damage. There is no evidence on the fact that orthodontic treatment alone might induce gingival recession, although it might lead the affected teeth (usually mandibular incisors or maxillary canines) to be involved in situations that act as predisposing...

When I was invited to coordinate Roberto Lima’s interview, I felt extremely honored. What can I say about Roberto? A man with an impressive curriculum and who has done so much for Orthodontics in Brazil as well as in the United States of America? Definitely it becomes a hard task to try to pinpoint the highlights of his career. His résumé speaks for itself. Therefore, instead of introducing the colleague, leader and outstanding orthodontist he is, I will use this opportunity to introduce...

Objective: Evidence is contradictory regarding the association between oronasopharyngeal abnormalities and malocclusion. The aim of the present study was to assess the association between oronasopharyngeal abnormalities and malocclusion (anterior open bite and posterior crossbite) in preschoolers. Methods: A cross-sectional study was conducted with a representative sample of 732 preschoolers aged 3-5 years old selected randomly from private and public preschools. Anterior open bite (AOB) and...

Objective: This paper analyzed whether nickel-titanium closed coil springs (NTCCS) have a different superelastic (SE) behavior according to activation and whether their force plateau corresponds to that informed by the manufacturer. Methods: A total of 160 springs were divided into 16 subgroups according to their features and activated proportionally to the length of the extensible part (NiTi) of the spring (Y). The force values measured were analyzed to determine SE rates and force...

Introduction: The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a multi-item psychometric instrument used to assess patients’ perspective of the impact specifically related to Orthodontics. The cross-culturally adapted Brazilian version of the PIDAQ has demonstrated good reliability, validity and acceptability. Objective: The aim of the present study was to test the validity and reliability of the Brazilian version of the PIDAQ for use among adolescents aged between 11...

Objectives: To evaluate the cephalometric changes in skeletal, dentoalveolar and soft tissue variables induced by Clark’s Twin Block (CTB) in Class II, Division 1 malocclusion patients and to compare these changes in different cervical vertebral maturation stages. Methods: Pre- and post-treatment/observation lateral cephalograms of 53 Class II, Division 1 malocclusion patients and 60 controls were compared to evaluate skeletal, dentoalveolar and soft tissue changes. Skeletal maturity was...

Objective: The aim of this study was to introduce a new method for bilateral distal movement of the entire maxillary posterior segment. Case report: A 17-year-old girl with Class I skeletal malocclusion (end-to-end molar relationships, deviated midline and space deficiency for left maxillary canine) was referred for orthodontic treatment. She did not accept maxillary first premolars extraction. A modified Hyrax appliance (Dentaurum Ispringen, Germany) was used for bilateral distalization of...

Introduction: A canted occlusal plane presents an unesthetic element of the smile. The correction of this asymmetry has been typically considered difficult by orthodontists, as it requires complex mechanics and may sometimes even require orthognathic surgery. Objective: This paper outlines the case of a 29-year-old woman with Class II malocclusion, pronounced midline deviation and accentuated occlusal plane inclination caused by mandibular deciduous molar ankylosis. Methods: The patient was...

This manuscript describes the treatment of a 27-year-old patient who was previously treated with two maxillary first premolar extractions. The patient had skeletal Class III malocclusion, Class III canine relationship, anterior crossbite, and a concave profile. As the patient refused orthognathic surgery, a miniplate was used on the right side of the lower arch as an anchorage unit after the extraction of mandibular first premolars, aiding the retraction of anterior teeth. At the end of...

Objective: This study evaluated the effectiveness of guided bone regeneration (GBR) carried out with xenogenic bone substitute (Bio-OssTM) and collagen resorbable membrane (Bio-GideTM) to improve gingival smile (GS) in patients with excessive vertical maxillary growth (EVMG). Methods: Twelve healthy women aged between 20 and 49 years old (mean age of 26 years), with 5 mm or more of gingival exposure during fully posed smile (FPS) due to EVMG, were included. Baseline digital photographs were...
