14 Products ORTHO TRIBUNE | NOv./DEC. 2009 Avex CXi Made from polycrystalline alumina, Avex CXi Ceramic Brackets offer translucence without sacrificing bracket integrity, bond strength or patient comfort. Bracket features include mesial and distal “pockets” that provide greater inter-bracket distance, reducing wire forces and improving patient comfort; metal slot liners to enhance strength and reduce friction; and purchase points on the tie wings that have a patented shape that is both round for comfort and pointed for easy ligation. The universal color identification marking and the same in/ out dimensions for each tooth as the Avex MX Stainless Steel Brackets, make the brackets completely interchangeable — an industry first. Opal Orthodontics (888) 863-5883 www.opalorthodontics.com f OT page 12 5. BRACE appliance maintains all the characteristics and elements of the Trainers. Therefore, it can produce the same effects reported by other Trainers as these effects are the result of the elements found in all TRAINER System Appliances. By stimulating development of the dental arches, there will be more room for the teeth, and the MYOBRACE can guide the teeth to align in a correct position through the tooth channels included in the appliance. This is one of the features that differentiates the MYOBRACE from the other Trainers. Based on all evidence presented here, it can be stated that the TRAINER System Appliances (including the MYOBRACE) are a viable and scientifically proven alternative to treat those patients who require treatment for malocclusions but who do not want treatment with fixed appliances such as brackets.
