Overview

The Carrière Motion Appliance uses a "Sagittal First" treatment philosophy — correct the Class II or Class III sagittal relationship before bonding full fixed appliances, rather than trying to address malocclusion simultaneously with leveling and alignment. A nickel-free SS bar is bonded to the buccal surfaces of the upper canine and upper first molar, spanning the premolars. A ball-and-socket joint between the molar pad and the bar allows distalization of the canine without tipping. Patients wear Class II or Class III elastics from the bar to the lower arch, correcting the sagittal relationship in approximately 3–6 months before full bracket bonding begins. Available in 22 sizes (to accommodate variation in canine-to-molar distance). A Class III version (CM3) delivers the same concept in reverse.

Clinical & technical

Mechanism of action

The bar transmits elastic forces (from patient-worn Class II elastics hooking to the lower archwire or a lower retainer) through the canine and molar as a unit, delivering a uniform distal force to the posterior segment. The canine pad's design prevents tipping of the canine during distalization. The result is a full sagittal correction of the molar/canine relationship to Class I before bracket bonding. Once Class I is achieved, the Carriere bar is debonded and comprehensive fixed appliances are placed.

Indications & case selection

Class II division 1 and 2 in patients requiring pre-orthodontic molar distalization; Class III cases (CM3 version); patients where full-arch bonding is not yet practical (unerupted teeth, poor oral hygiene) but sagittal correction can begin; adolescents and adults; combined with lower retainer and Class II elastics.

Contraindications & limitations

Compliance required for elastic wear (same as all elastic-based corrections); severe Class II may require additional Class II mechanics after Carriere correction; bonding failure can occur if teeth are not properly isolated; third molars must be managed.

Design & fabrication

Components & materials

Lab fabrication notes

Manufactured by Henry Schein Orthodontics — chairside direct bond. No lab fabrication required for the Carriere appliance itself. Lower retainer (if used as the lower anchor) may be lab-fabricated.
