10 ortho 1 2016 “ An elegant and efficient approach” An interview with Dr Luis Carrière, Spain, developer of the Carriere MotionTM Class III Appliance DrCarrière,howlonghastheMotionappliancefor Class III mal occlusions been on the market? Wepresentedtheapplianceforthefirsttimeatthe American Association of Orthodontists meeting in 2015. The approach is not entirely new and we have been working on it for a couple of years. The Class II appliance was invented for Class II cases, but many participantsinseveralcoursesItaughtonClassII,es- peciallyinAsia,askedwhetheritcouldalsobeusedin Class III cases. In response to this, we decided to ex- plorethistoseeifitwasagoodoption.Theresultswe achieved with the use of the Carriere Motion Class II Appliance in Class III cases were amazing. This made us realise that this appliance was really changing the relation between the mandible and the maxilla, harmonising soft tissue and balancing the patient’s face. We were completely surprised by the fantastic facial outcomes that we achieved with this minimalapproach.Wethusdecidedtocreateaspecial design according to the needs of the mandible, the Carriere Motion Class III Appliance. Could you please describe in short the design fea tures of the Carriere Motion Class III Appliance? Why does it only have a simple molar bonding pad withasmallstepinthearmandwhydidyouaban don the joint design you have with the Class II Motion Appliance (rotation of the molar)? Ifwelookattheocclusionofthelowerarchinrela- tion to the upper, normally there is an inclination of the posterior segments owing to the fact that the buccal side of the mandibular molars should fit be- tween the buccal and the lingual aspects of the max- illary ones. This means that the design of the tradi- tional Class II pad ball is too bulky. Often, it can interferewiththeocclusionatthestartofbonding,so we decided to create a flat surface on the posterior segment in order to avoid unnecessary collisions in Class III mandi bular positioning with the appliance. Whatwehavecreatedisadesignthatisverycleanand simple with only those features that are needed. We have also adapted it to the requirements of Class III malocclusions. While we used Motion Class II Appli- ancesinClassIIIpatientsinitially,weneededtocreate somethingthatwasreallysuitedtoClassIIIcases.We achieved this by flattening the profile, which is now very slim and straightforward. It is very important to understand that in 95 % or more of our fixed cases, we start treatment with the Carriere Motion Appliance, which is not only re- stricted to Class II or III malocclusions but also ex- tremelyusefulforthosecasesinwhichwehaveminor crowding.Weneedtoopenlimitedspacebetweenthe Dr Luis Carrière creator of the newly developed Motion™ Class IIIAppliance.
