What are the key design components of a Hawley retainer?
The Hawley retainer consists of three primary components:
- Custom-fitted acrylic base plate made from medical-grade PMMA that conforms to the palatal contours
- Labial bow wire (typically .032" stainless steel) that spans the anterior teeth with adjustment loops near the canines
- Retention clasps such as Adams clasps, ball clasps, or C-clasps that secure the appliance to posterior teeth.
This design allows for both stability and adjustability throughout the retention period.
