Maxillary Expansion and Its Effects on Circummaxillary Structures: A Review

Area of Science:

• Orthodontics
• Craniofacial Development

Background:

• Transverse maxillary discrepancies, particularly narrow upper arches, are prevalent in orthodontic patients.
• These discrepancies manifest as narrow palates, posterior crossbites, and anterior crowding.

Purpose of the Study:

• To review maxillary expansion techniques for correcting transverse discrepancies.
• To explore the effects of maxillary expansion on the nasomaxillary complex.

Main Methods:

• Review of literature on orthodontic treatments for maxillary expansion.
• Analysis of clinical manifestations and therapeutic approaches.

Main Results:

• Common therapies include slow, rapid, and surgically assisted rapid maxillary expansion.
• Maxillary expansion impacts the mid-palatine suture, maxilla, mandible, TMJ, soft tissues, and teeth.

Conclusions:

• Maxillary expansion is crucial for treating transverse discrepancies.
• Understanding the comprehensive effects on the nasomaxillary complex is vital for treatment planning.
