AIMS To assess the effects of two-phase treatment with the Herbst and the preadjusted edgewise appliances on upper airway dimensions and to investigate the correlation between changes in the upper airway dimensions and skeletal morphologies. METHODS A total of 27 Chinese male adolescents aged 12.8 ± 1.3 years were selected. Lateral cephalograms were collected to assess the skeletal morphology...

This case report highlights the treatment of a skeletal Class II malocclusion with pseudoanodontia that indicated clinical but not radiographic absence of teeth. A 21-year-old female patient presented with a skeletal Class II malocclusion with an orthognathic maxilla and a retrognathic mandible, with Angle’s Class I malocclusion with rotated maxillary and mandibular anteriors with fourteen impa...

A 12-year-old female patient presented with proclined upper anteriors on a class II skeletal base, a retrognathic mandible and high maxillary- mandibular plane angle. Lower first molars were mesially tipped and lower second premolars were impacted. Treatment plan included uprighting and distalising the lower molars followed by growth modulation with Jasper Jumper to correct the mandibular retro...

The present case report describes the treatment of a 12-year-old boy who had skeletal Class III malocclusion with concave facial profile, hypodivergent facial pattern with anterior cross bite and deep overbite. The treatment plan included rapid palatal expansion with maxillary protraction and fixed edgewise appliance. The results show that anterior cross bite was corrected and facial esthetics ...

This case report explores the treatment of a 13-year-old male patient with severe dental crowding and periodontal issues using non-extraction orthodontic combined root coverage procedure. The presented skeletal class 1 base malocclusion, multiple anterior crossbites, along compromised lower central incisor gingival recession. Despite option extraction, declined this approach, final goal was to ...

The purpose of this study was to evaluate the skeletal and dentoalveolar changes occurring during two-phase orthodontic treatment. A cephalometric study of Class II correction was carried out in 40 subjects (20 females, 20 males) who had been treated with the acrylic-splint Herbst appliance immediately followed by a second phase of preadjusted edgewise therapy. The average age at the start of H...

The changes in soft tissue profile for 66 Angle's Class III malocclusion subjects treated either with the Function Regulator, or Upper Removable Appliances, or the Edgewise Appliance were assessed by comparing cephalometric radiographs taken before and after correction of the anterior occlusion. While the mean soft tissue profile in all groups improved in relation to a Control Group, the FR.III...

This was a retrospective, longitudinal cephalometric and cast study of 29 white patients at pretreatment, posttreatment, and an average of 6 years 3 months postretention. The goal was to assess changes with treatment and retention with the expanding mandibular lingual arch appliance in conjunction with fixed edgewise treatment. Seven mandibular cast measurements were assessed, including arch cr...
