Skeletal Malocclusions

It is important to determine skeletal or dental expansion

Skeletal expansion is expanding the maxilla palatal suture normally by using a palatal expander so that the bottom and upper teeth will fit together better.

Dental expansion is widening the alveolar process and dental arch.

Expansion is a common method for creating space.

Extraction Cases:

When to consider extraction treatments:

• Too much incisor advancement
• To correct/prevent intrusion on finish
• To correct/prevent open bite
• To correct/prevent periodontal compromise
• Convex profile - extract to reduce protrusion
• Missing teeth
• Too much Class II or Class III > 4mm
• Extraction to make lips competent at rest
• Badly damaged teeth
