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 paper presents an experimental investigation into the effects of turbulence ingestion on aerodynamic noise characteristics rotor blades in edgewise flight. A small-scaled, two-bladed was used study. The test utilised two turbulence-generating grids, to generate inflows with different characteristics, and compare them baseline configuration laminar inflow. experiments were set at forwarding...

The aim of this in vitro study was to investigate the frictional characteristics of two types of self-ligating brackets ('A' Company Damon SL and Adenta Time brackets) and two types of pre-adjusted edgewise brackets (TP Tip-Edge and 'A' Company Standard Twin brackets). The test brackets were glued to steel bars and aligned using a preformed jig. Five combinations of archwire size and material w...

The aim of this study was to investigate long-term effects induced by rapid maxillary expansion (RME), followed by comprehensive orthodontic treatment, in a sample of 42 patients compared with normal growth changes in a sample of 20 subjects. Treated subjects underwent Haas-type RME with 2 turns a day (0.25 mm per turn) until the expansion screw reached 10.5 mm (about 21 days). The Haas expande...
