Rohs Retainer Hooks

Adams Clasp

Most common type used in Hawley retainers.

Engages the undercuts of molars.

Provides strong retention and is adjustable.

Ball Clasp

A wire with a small ball end that fits between teeth (often premolars).

Easier to fabricate and adjust.

Used for light retention.

C-Clasp (Circumferential Clasp)

Wraps partially around the tooth, engaging undercuts.

Common on premolars and molars.

Offers moderate retention.

Arrowhead or Triangular Clasp

Designed for esthetics and minimal visibility.

Often used on anterior teeth.

Provides less retention than Adams clasps.

Functions of Retainer Hooks:

Stabilization: Keeps the retainer in position by gripping onto specific teeth.

Retention: Ensures the retainer doesn’t shift or fall out during normal activities like talking or eating.

Adjustability: Allows orthodontists to fine-tune the fit for comfort and effectiveness.

Materials:

Typically made from stainless steel or nickel-titanium wire for strength, biocompatibility, and resistance to corrosion.
