Hawley Retainer with C Clasps
Appliance Purpose / Function:
The primary function of the Hawley Retainer with “C” clasps is to provide retention of the anterior teeth. Retention is provided by a labial 3 x 3 labial bow.
Appliance Components:
- Acrylic Arch
- Labial bow with adjustment loops anchored in the acrylic arch
- Circumferential clasps around the distal of the second molars
Suggested Materials:
- Wire: Chromium Cobalt wire or Stainless-Steel wire
Options:
- May be made with facial acrylic
Appliance Fabrication Standards:
- Labial bow is formed from 3 x 3
- The adjustment loops begin just distal to the mid point on the facial of the cuspid
- The loop ends at the interproximal of the cuspid and the 1st bicuspid
- The wire is in intimate contact with the teeth in the interproximal area as it crosses the occlusion
- The “C” clasp is formed to sit below the height of contour on the second molar
- The “C” clasp is maintains intimate contact with the tooth on the buccal and distal surfaces
- The palatal wires are formed about 1mm off the tissue to provide clearance for acrylic
