Aims: To evaluate changes in transverse dimensions of upper arch and thickness of the buccal bone plate in patients undergoing orthodontic treatment during the leveling phase.

Materials And Methods: Sixteen patients aged between 11 and 30 years, presenting with class I and II malocclusion, with minimum of 2 mm crowding treated without extraction, were divided into two groups: GI (n = 8), self-ligating brackets (Easyclip Aditek), and GII (n = 8), conventional preadjusted brackets (3M Unitek). The intercanines, interpremolar, and intermolar widths were measured in dental casts using a digital caliper, before (T1) and after 6 months of treatment (T2).

Effects of green tea on the shear bond strength of orthodontic brackets after in-office vital bleaching.

The application of bleaching agents before placement of resin-bonded fixed appliances significantly, but temporarily, reduces bond strength to tooth structure. Antioxidants have been studied as a means to remove residual oxygen that compromises bonding to bleached enamel. This in vitro study evaluated whether green tea (GT) could restore the shear bond strength between bonded orthodontic brackets and bleached enamel.

Tomographic evaluation of the temporomandibular joint in malocclusion subjects: condylar morphology and position.

The aim of this study was to investigate condyle concentricity and morphology, and their association with Class I and II malocclusions (Angle).

Early treatment protocol for skeletal Class III malocclusion.

Skeletal Class III malocclusion, with its unpredictable and unfavorable nature, has been characterized by a growth pattern with doubtful prognosis regarding orthodontic mechanics, even when performed early. For a long time, Class III malocclusion was regarded as a synonym of mandibular prognathism, regardless of the affected skeletal structures. Mandibular growth, essentially determined by genetic factors, could barely be controlled by early orthodontic interventions.

Comparison of manual, digital and lateral CBCT cephalometric analyses.

Objective: The aim of this study was to compare the reliability of three different methods of cephalometric analysis.

Material And Methods: Conventional pretreatment lateral cephalograms and cone beam computed tomography (CBCT) scans from 50 subjects from a radiological clinic were selected in order to test the three methods: manual tracings (MT), digitized lateral cephalograms (DLC), and lateral cephalograms from CBCT (LC-CBCT). The lateral cephalograms were manually analyzed through the Dolphin Imaging 11.

The impact of healing time before loading on orthodontic mini-implant stability: a histomorphometric study in minipigs.

Objective: To evaluate healing time before loading, areas compression and tension and location of insertion on mini-implant stability.

Design: Six minipigs were used. Each animal received 3 mini-implants in each quadrant: 1 mini-implant was used as an unloaded control (G1, n=24); the other 2 were loaded with 150g-force at three time intervals (G2: immediate loading, G3: after 15 days and G4: after 30 days), with 16 mini-implant in each experimental group.

Reliability of a method to conduct upper airway analysis in cone-beam computed tomography.

The aim of this study was to assess the reliability of a method to measure the following upper airway dimensions: total volume (TV), the nasopharyngeal narrowest areas (NNA), and the oropharyngeal narrowest areas (ONA). The sample consisted of 60 cone-beam computed tomography (CBCT) scans, evaluated by two observers twice, using the Dolphin 3D software (Dolphin Imaging & Management solutions, Chatsworth, California, USA), which afforded image reconstruction, and measurement of the aforementioned dimensions. The data was submitted to reliability tests, by the intraclass correlation coefficient (ICC), and the Bland & Altman agreement tests, with their respective confidence intervals (CI) set at 95%.

Multidisciplinary approach to the establishment and maintenance of an esthetic smile: a 9-year follow-up case report.

In addition to providing functionality to patients, contemporary dentistry strives for esthetic excellence. Patients with anterior impairments, such as shape, size, and position alterations, have compromised smile harmony. A multidisciplinary orthodontic-operative dentistry approach has improved the treatment of these patients, since the use of orthodontic appliances in association with direct composite restorations can solve many esthetic problems.

Serial extraction: 20 years of follow-up.

This paper reports a case treated by a serial extraction program at the mixed dentition stage followed by a corrective orthodontic treatment, with a long-term follow-up period. Twenty years after the interceptive treatment, a harmonious face was observed along with treatment stability in the anterior posterior direction, deep overbite (which has been mentioned as a disadvantage of the serial extraction program), and a small relapse of anterior tooth crowding. All these conditions have been regarded as normal occurrences for most orthodontic treatments with a long-term follow-up period.

Posterior crossbite--treatment and stability.

Posterior crossbite is defined as an inadequate transversal relationship of maxillary and mandibular teeth. Even when eliminating the etiologic factors, this malocclusion does not have a spontaneous correction, and should be treated with maxillary expansion as early as possible. This treatment aims at providing a better tooth/skeletal relationship, thereby improving masticatory function, and establishing a symmetrical condyle/fossa relationship.

Early treatment of Class III malocclusion: 10-year clinical follow-up.

Angle Class III malocclusion has been a challenge for researchers concerning diagnosis, prognosis and treatment. It has a prevalence of 5% in the Brazilian population, and may have a genetic or environmental etiology. This malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis.

The nance lingual arch: an auxiliary device in solving lower anterior crowding.

After exfoliation of the primary incisors and eruption of the permanent incisors, the dentist has the opportunity of observing closely the beginning of occlusal changes. In several cases, alterations, such as lower anterior crowding, can be prevented and treated with proper follow-up. In the mixed dentition, one of the mechanisms for maintaining space and favoring dental alignment is to preserve leeway space before permanent second molar irruption.
