A novel appliance for Class II dentoalveolar correction.

Abstract

In recent years, a segmental approach to Class II correction has gained popularity among orthodontists. This concept is best represented by the Carrière Motion 3D™ Class II Appliance (CMA), which is an efficient and effective appliance for the treatment of Class II malocclusions. Although it is original and innovative, it also has some inherent flaws that can potentially interfere with its daily use. A segmental approach is described, based on a section of 0.016 × 0.022-inch stainless steel archwire connected to a molar band distally and to a bracket on the mesial side. This simple alternative presents a 'do-it-yourself' and an easy-to-construct mechanism that employs the same principles and identical mechanics to achieve Class II correction yet overcomes most of the disadvantages of other modalities. In our clinic, we found that this optional, useful sectional appliance can correct Class II malocclusion effectively, predictively and on a regular basis.
