About clasps
A preformed clasp is built into an appliance such as a partial denture and helps stabilize it by fastening it to an adjacent tooth. A circumferential clasp encircles a tooth by more than 180 degrees.
A framework is the skeletal portion of a prosthesis, usually metal, around which and to which the remaining portions are attached. Cobalt-chromium alloy remains the most common material for removable partial denture frameworks.
The FDA lists the preformed clasp as a Class I device (21 CFR 872.3285).
How clasps, lingual bars, mesh and strengtheners differ
- Clasps — The part that grips the tooth; when overloaded, cast clasps tend to break and the more flexible wrought ones to deform.
- Strengtheners — Preformed grids, braids and plates that reinforce the acrylic base.
- Mesh — Sheet mesh embedded in the acrylic base as reinforcement.
- Lingual Bars — The bar that joins the two sides of a lower partial denture.
What to look at when choosing
Clasp material: in one study cast clasps gave the highest retentive forces, and round wrought wire of 1 mm diameter the next highest. Nickel-free wrought wire was more flexible than stainless steel and exerted less retentive force.
Metal or wax: some clasps, bars and retentions on this shelf are wax shapes. Dental wax is used to build the patterns from which custom metal prostheses are cast.
Framework metal: a study attributes the place of cobalt-chromium to its high elastic limit, resistance to wear and corrosion, and biocompatibility.
