"Sagittal First" Approach Using Carriere Motion 3D Appliance: A Case Report.

Area of Science:

• Orthodontics and Dentofacial Orthopedics
• Pediatric Dentistry
• Craniofacial Growth Modulation

Background:

• Class II malocclusion management in adolescents often involves growth modulation, with fixed functional appliances typically used later in treatment.
• The Carriere Motion 3D appliance offers an alternative approach for early sagittal correction of Class II malocclusion before comprehensive fixed appliance therapy.

Observation:

• A 15-year-old male patient presented with Class II malocclusion characterized by a retruded mandible and proclined maxillary incisors.
• Treatment involved initial application of the Carriere Motion Appliance (CMA) with Class II elastics for mandibular advancement, alongside lower arch alignment.

Findings:

• The CMA facilitated significant mandibular advancement, achieving a Class I molar and canine relationship within six months.
• Dentoalveolar changes were primary, with notable sagittal and vertical skeletal improvements observed.
• The appliance was associated with patient comfort and fewer reported side effects compared to other functional appliances.

Implications:

• The Carriere Motion Appliance (CMA) presents an efficient 'Sagittal First' strategy for correcting Class II malocclusion, potentially avoiding extractions.
• Early intervention with CMA can simplify subsequent orthodontic treatment phases.
• This approach offers a comfortable and effective alternative for adolescent mandibular advancement and Class II correction.
