A laboratory examination of the behaviour of cast cobalt-chromium clasps.
Cast cobalt-chromium clasps, long and short, tapered and untapered, were studied. It is shown that the behaviour of apparently identical clasps is inconsistent. Permanent deformation appears to commence during the first month of wear, and after 6 months' wear the retentive quality of almost all of the clasps is impaired.
