INTRODUCTION The objective of this study was to evaluate natural changes in maxillary posterior alveolar height (MPAH) and axial inclination of the maxillary first molars (AIMFM) in subjects with Class II malocclusion to determine the validity of predictive equations. METHODS Longitudinal records of 30 untreated white subjects (13 girls, 17 boys) with(More)
This study evaluated the changes in the skeletal profile of Class II subjects submitted to orthodontic treatment. The experimental group comprised the lateral cephalograms of 30 Brazilian subjects (17 female and 13 male subjects) obtained between the mean ages of 11.1 years (initial) and 15.1 years (final) and treated with cervical headgear and edgewise(More)
OBJECTIVE To evaluate the relationship between the stages of dental formation and the timing of eruption of mandibular second premolars. MATERIALS AND METHODS The sample comprised panoramic radiographs of 25 children, 7 to 12 years old, observed by space supervision during development of dentition. The initial radiograph (T1) was taken in the mixed(More)
OBJECTIVE To evaluate the amount of maxillary protraction with face mask in complete unilateral cleft lip and palate patients submitted to two distinct rapid maxillary expansion (RME) protocols. MATERIAL AND METHODS The sample consisted of 20 individuals (nine boys and 11 girls; mean age of 10.4 +/- 2.62 years) with unilateral complete cleft lip and(More)
The aim of this article is to discuss an alternative treatment for adult patients who have a dental or skeletal Class III relationship. A 20-year-old woman presented with a dental and skeletal Class III relationship and a transverse maxillary deficiency. Surgically assisted rapid maxillary expansion was followed by maxillary protraction with a face mask and(More)
OBJECTIVE To evaluate and compare the eruption rates of lower second premolars (LPm2) at different developmental stages using cone-beam computed tomography (CBCT). MATERIALS AND METHODS Retrospectively, 31 individuals (9.77 ± 1.25 years) had their LPm2 scored according to the Demirjian method, and afterwards they were split into three groups according to(More)
This article describes the orthodontic relapse with mandibular incisor fenestration in a 36-year-old man who had undergone orthodontic treatment 21 years previously. The patient reported that his mandibular 3 × 3 bonded retainer had been partially debonded and broken 4 years earlier. The mandibular left lateral incisor remained bonded to the retainer and(More)
OBJECTIVE The objective of this study was to evaluate a sagittal variation on the lower incisors with the use of the lingual arch on the transition from mixed to permanent dentition. METHODS The sample was constituted of 44 Caucasian patients (26 girls and 18 boys), divided in two groups: CG, control group, monitoring the lower arch space with no(More)
INTRODUCTION Combined treatment offers advantages for partially edentulous patients. Conventional implants, used as orthodontic anchorage, enable previous orthodontic movement, which provides appropriate space gain for crown insertion. OBJECTIVE This case report describes the treatment of a 61-year and 10-month-old patient with negative overjet which made(More)
Rapid orthodontic extrusion is indicated for cases involving biological space invasion of the periodontal ligament in which the surgical increase of the clinical crown can compromise esthetics or the support of the adjacent teeth. This article presents the case report of a tooth with radicular perforation 1.0 mm below the bone crest. A procedure to restore(More)
