The Effectiveness of Tipback Mechanics for Correction of Class II Malocclusion
… root uprighting. Lateral cephalograms of growing class II subjects taken at completion of leveling and aligning, after tipping back the molar, and after uprighting the molar roots were analyzed. The technique resulted in 1.95 mm distalization, 6.55 degrees distal tipping, and 1.4 mm extrusion of …

Fixed Functional Appliance Systems in Orthodontics
Class II malocclusion is one of the main orthodontic problems affecting the population. Through advancing the mandible in a sagittal and vertical plane using functional appliances, dentoalveolar and skeletal changes occur. Fixed functional appliances are able to correct skeletal abnormalities for …

IDENTIFICATION OF GENETIC VARIANTS THROUGH WHOLE EXOMESEQUENCING IN PHENOTYPES WITH SKELETAL CLASS IIMALOCCLUSION BAD RESPONDERS
Skeletal malocclusions are complex craniofacial growth and developmental problems due to hereditary and environmental factors. They are a set of human morphologic characteristics that both exceed or present deficiency of maxillary and mandibular dimensions, resulting in an improper relationship of …

ACTN3 R577X GENOTYPES ASSOCIATE WITH CLASS II AND DEEP BITE MALOCCLUSIONS
… ACTN2 is expressed in slow type I and fast type II fibers whereas ACTN3 is expressed only in fast fibers. ACTN3 homozygosity for the 577X stop codon (i.e. changing 577RR to 577XX - the R577X polymorphism) results in the absence of alpha-actinin-3 in about 18% of Europeans, diminished fast …

Abstract Effect of timing on treatment outcomes and surgical complications of orthognathic surgery in Class II patients
Introduction Class II malocclusions can be treated with a combination of orthodontics and orthognathic surgery. The severity of the malocclusion and growth potential play an important role in the treatment decision. Treatment involving orthognathic surgery is usually recommended after active growth …

Three-Dimensional Evaluation of the Effect of Maxillary Incisor Retraction on the Palatal Bone and Root Resorption
… Increased root resorption was correlated with Class II malocclusion, increased OJ and OB, greater number of extracted premolars, long treatment duration, proximity of incisor roots to palatal cortex, and apical extrusion. Increased palatal alveolar bone height loss was correlated with greater …

Treatment Effects of the Mandibular Anterior Repositioning Appliance (MARA) and Conventional Orthodontic Mechanics on Temporomandibular Joint Morphology: A Comparison Using Cone Beam Computed Tomography
… of condylefossa remodeling and growth seen in Class II patients using functional appliance therapy. Some clinicians and researchers have found that that the use of functional appliances increases the amount of condylar growth and subsequent Class II skeletal correction; others believe that the …

CBCT and Cephalometric Analysis of the TMJ Complex after Treatment Using a MARA Appliance
… a fixed appliance intended for the correction of class II malocclusion. Many advocate the use of the MARA appliance to minimize patient non-compliance with treatment; however, little information is known as to the skeletal changes in the temporomandibular complex. The purpose of this study is to …

Cephalometric Evaluation of Mara Therapy in the Treatment of Class II Malocclusions
… cephalometric analysis of patients with Class II, division 1 malocclusions at the start of treatment. There were 51 children treated by a single clinician with a MARA in combination with Edgewise appliances. The comparison group consisted of subjects treated with fixed Edgewise appliances …

Cephalometric Evaluation of Bionator Therapy in the Early Treatment of Class II Malocclusions
<p>Early or two-phase orthodontic treatment of Class II malocclusions is a debated topic in orthodontic circles primarily because the benefits of early intervention have not been consistently reproduced among researchers. The present study was a retrospective analysis of cephalograms from patients …

Cephalometric Evaluation of One-Phase and Two-Phase Treatment Alternatives in Matched Class Ii Subjects
<p>“Early” or two-phase orthodontic treatment of Class II malocclusions is a highly debated topic in the orthodontic literature. We report here on a retrospective cephalometric study of patients with Class II, division 1 malocclusions. One group consisted of 32 consecutively treated patients who …

Use of CVM Stages in Assessment of Young Orthodontic Patients to Estimate Growth Potential
… discrepancies is an important part of Class II correction in orthodontic treatment; however, orthodontists rarely have the opportunity to choose when a patient is referred to them. Diagnostic records can assist the orthodontist in determining how much growth a patient has remaining. The …

Children and adolescents and modified twin block for Class II division 1 malocclusion compared to controls: quantitative and qualitative analyses
… 3D soft tissue facial changes in children with Class II division 1 malocclusion (II/1M) compared to children with II/1M awaiting treatment who served as controls. • To assess the effect MTB treatment has on family quality of life (QoL) and on both the parent’s perception of their child’s OHRQoL …
