Orthodontic Chin Cup Extraoral Appliance – Standard Grade

The Orthodontic Chin Cup is an extraoral orthopedic appliance used in the management of mandibular prognathism and skeletal Class III malocclusion in growing patients. The appliance delivers posteriorly directed restraining forces to the mandible via a contoured chin cup connected to a headgear strap or extraoral frame assembly, supporting redirection of mandibular growth during the active skeletal development phase in pediatric and adolescent orthodontic patients.

Clinical Advantages

Delivers controlled posterior restraining forces to the mandible in growing patients
Contoured chin cup shell design supports stable chin contact during prescribed wear periods
Adjustable headgear strap connection for force vector and magnitude calibration
Compatible with standard orthodontic headgear and extraoral force delivery systems
Cost-effective option for orthodontic clinic inventory and patient supply programs

Indications & Clinical Use

Mandibular prognathism management in growing pediatric and adolescent patients
Skeletal Class III malocclusion treatment via posterior mandibular growth restraint
Early interceptive orthodontic treatment adjunct for midface and mandibular orthopedic correction
Used in combination with intraoral orthodontic appliances for comprehensive Class III management

Material & Performance

Cup construction: Contoured rigid or semi-rigid shell with inner contact lining
Force delivery: Adjustable headgear straps connected to extraoral frame or occipital anchorage
Inner lining reduces soft tissue pressure at chin contact area during wear
Country of manufacture: China

Clinical Workflow

Fit and adjust chin cup to patient chin contour and facial dimensions
Connect chin cup to headgear strap or extraoral frame at prescribed force vector angle
Calibrate force levels per prescribed orthopedic treatment protocol
Instruct patient on daily wear duration, force maintenance, and appliance hygiene procedures
Monitor mandibular growth response and skeletal correction at scheduled review appointments
