interview Ortho Tribune U.S. Edition | PCSO PREVIEW 20154 Carrière explains facially driven treatment for Class II and Class III By Ortho Tribune Staff D r. Luis Carrière obtained his dental degree from the University of Com- plutense in Madrid (UCM), in 1991. He then attended the University of Barcelona (UB), where he completed his orthodontic training and received his master of science in orthodontics in 1994. In 2006, he received his doctorate in or- thodontics, cum laude, from the Univer- sity of Barcelona. Carrière is the inventor of the Carriere Self-Ligating Bracket and the Carriere MotionTM Appliance. He is a world-renowned lecturer on these prod- ucts, in addition to many other topics. How long has the Motion appliance for Class III malocclusions been on the mar- ket? We just presented the appliance this year at the AAO annual meeting, but the ap- proach is not new; we have been working on it for few years. The Class II appliance was invented for Class II cases. But after giving several courses on Class II, espe- cially in Asia, many doctors were asking about the Class III possibility of using it. So one day we started to try and see if this was a good option, and it’s showed amazing results of using the Class II mo- tion appliance in Class III cases. So we realized, this appliance was re- ally changing the relation in which the mandible interacts with the maxilla, har- monizing soft tissues and balancing the face of the case. We were amazed and to- tally surprised about the fantastic facial outcomes that we were having only with a minimal approach like this. We decided to create a special design according to the needs of the mandible: the Class III Mo- tion appliance. So the approach is not new. But the appliance by itself, the real strictly Class III appliance, is brand new and officially presented at the 2015 AAO Annual Meeting. Could you briefly describe the design fea- tures of the Motion Class III Appliance? Why does the Class III Motion only have a simple molar bonding pad with this little step in the arm? What is the function of this little step? Why did you give up on the joint design you have with the Class II Motion (rotation of the molar)? If we take a look at occlusion of the lower arch in relation with the upper, normally there is an inclination of the posterior segments because the buccal side of the lower molars should fit in between the buccal and the lingual pad of the upper ones. This means that if we use the tra- A Q&A with the inventor of the Carrière Self-Ligating Bracket and the Carrière Motion Appliance, including the new Class III appliance Fig. 1: Carrière Class III Motion Appliance.

We decided to create a flat surface on the posterior segment in or- der to avoid the unnecessary collisions on the Class III mandibular positioning of the appliance. Now, what we have created is a design that is very clean and simple but has ex- actly the same features that we need. But, at the same time, we have adjusted it to the real needs of the Class III malocclu- sion. So we used Class II Motion applianc- es at the beginning in Class III patients, but we needed to create something that was really special and was really dedi- cated to the Class III cases. We did that by flattening the profile, that is now very slim, and it is a very clean appliance, completely dedicated and designed for Class III treatments. It is very important to understand that the Carriere Motion appliance is the way in which we start 95 percent or more of our fixed cases in our office. This means that Motion is not restricted only to Class II or Class III malocclusions but is also ex- tremely useful for those cases in which we have small crowding, and we need to open limited space in between upper or lower incisors in order to align the upper teeth or the lower anterior teeth without protruding. At the same time, this accomplishes what we like to call a Super Class I pos- terior occlusion. So we use the Motion to start the case, simple and minimalistic. I personally feel this is an elegant and effi- cient approach to the case that diminish- es dramatically the period of brackets in mouth for our patients. Shortening the bracket-in-the-mouth stage is a very im- portant factor to most of society today. Regarding invisible systems such as Invisalign, this approach works amaz- ingly well in simplifying the treatment and dramatically shortening the aligner period. So many complex cases of Class ” See CLASS III, page 6
