Material and Method: With the purpose of investigating the occurrence, localization and extension of possible root resorptions after fixed appliance treatment with a continuous torque force, 28 upper first premolars orthodontically indicated for extraction from 14 patients were analyzed by scanning electron microscopy. Tooth movement was carried out with(More)
An ultrastructural study of the cementum and periodontal ligament (PDL) changes after continuous intrusion with two different and controlled forces in humans was carried out. Twelve first upper premolars, at stage 10 of Nolla, orthodontically indicated for extraction from six patients (mean age 15.3) were used. They were divided into three experimental(More)
OBJECTIVE To determine the frequency and type of lesions of the temporomandibular joints (TMJ) as well as orthodontic alterations present in patients with juvenile rheumatoid arthritis (JRA). METHODS Twenty-six patients had their TMJ evaluated clinically and by high resolution computer tomography. The patients were also submitted to orthodontic(More)
A scanning electron microscopy study of possible root resorptions and their localization after application of continuous forces of different magnitudes was conducted. Twelve upper first premolars, indicated for extraction, were previously intruded with constant forces. The teeth were divided into 3 groups: 1. non-moved control teeth, 2. continuous force(More)
OBJECTIVE To evaluate the long-term skeletal and soft tissue changes induced by the bionator in Class II subjects. MATERIALS AND METHODS The treatment sample consisted of 20 Class II patients (6 males and 14 females) treated consecutively with the bionator. The sample was evaluated at T1, start of treatment; T2, end of bionator therapy; and T3, long-term(More)
OBJECTIVE To evaluate the risk of root resorption, individual finite element models (FEMs) of extracted human maxillary first premolars were created, and the distribution of the hydrostatic pressure in the periodontal ligament (PDL) of these models was simulated. MATERIALS AND METHODS A continuous lingual torque of 3 Nmm and 6 Nmm respectively was applied(More)
OBJECTIVE To identify clastic cells on the root surfaces of torqued human premolars. MATERIALS AND METHODS A continuous force of 600 cNmm was applied to upper first premolars in patients 13-16 years of age by using a precise biomechanical model with superelastic wires (NiTi-SE). The 28 teeth in 14 patients were divided into five groups (control(More)
OBJECTIVE To quantify longitudinal cranial base growth from prepubertal through postpubertal stages of development, as defined by biological indicators of individual skeletal maturity (cervical vertebral maturation - CVM) method and to determine if there is sexual dimorphism resulting from cranial base growth. DESIGN A longitudinal cephalometric study. (More)
The aim of the present investigation was to provide information about the long-term effects and optimal timing for class-II treatment with the Bionator appliance. Lateral cephalograms of 23 class-II patients treated with the Bionator were analyzed at three time periods: T1, start of treatment; T2, end of Bionator therapy; and T3, long-term observation(More)
OBJECTIVE To analyze the long-term skeletal and dentoalveolar effects and to evaluate treatment timing of Class II treatment with functional appliances followed by fixed appliances. MATERIALS AND METHODS A group of 40 patients (22 females and 18 males) with Class II malocclusion consecutively treated either with a Bionator or an Activator followed by(More)
