Intraoral craniofacial manipulation by using MRI appliance

Area of Science:

• Orthodontics
• Craniofacial Surgery

Background:

• Maxillary hypoplasia and transverse discrepancies often require complex orthodontic interventions.
• Surgical-orthodontic management aims to correct skeletal and dental relationships for improved facial aesthetics and function.

Observation:

• A novel approach utilizing the Maxillary-Rotation-Impaction (MRI) appliance was employed.
• The MRI appliance facilitated controlled rotation and impaction of the maxilla.
• Subsequent use of a transverse expansion screw addressed maxillary arch width deficiency.

Findings:

• The combined MRI appliance and expansion screw technique effectively corrected the transverse and vertical discrepancies of the maxilla.
• Fixed orthodontic appliances were used for final alignment, resulting in a Class I occlusion.
• The treatment achieved harmonious positioning of facial bones and dental structures.

Implications:

• This case demonstrates a viable orthodontic strategy for managing complex maxillary deficiencies.
• The MRI appliance offers a predictable method for maxillary rotation and impaction.
• Achieving ideal facial aesthetics and a stable Class I occlusion is possible with this combined approach.
