Space Gaining Methods

Space Gaining Methods

Write a short note on the expansion of arches for space gaining in orthodontics.
Answer. Expansion of arches is a noninvasive method of gaining space.

• It is usually undertaken in patients having constricted maxillary arch or in patients with unilateral or bilateral crossbit e. Expansion can either be skeletal or longitudinal skeletal expansion, which involves the splitting of the thmidpalatene suture, while dentoalveolar expansion produces dental expansion with no skeletal change.
• Expansion is brought about by various appliances that incorporate jack screws or by use of springs.

Types of Expansions

They are of three types.e.

• Orthodontic/dentoalveolar: It leads to dental expansion
• Result from the intrinsic forces exerted by the tongue.
• Skeletal/orthopedic: It results from the m splitting of the midpalatal suture.

Type of Expansion Appliances

They are of two types, i.e., maxillary and mandibular:

• Maxillary
  • Slow

• • • Removable: For example, Coffin spring and Active plate with Screws or Z-springs
    • Fixed: For example, W-arch, Quad helix, Fixed appliances with expansion screws
  • Rapid
    • Banded RME: For example, Hass, Isaacson, Derichsweiler
    • Bonded RME: For example, Cast metal/acrylic splints
• Mandibular: For example, Lower Schwarz plate.
