| description | Introduction: Retention and esthetics are believed to play
a crucial role in deciding the success of removable partial
dentures.
Aim: To compare retention of acetal resin and cobalt–chromium
clasps.
Materials and Methods: A finite element model was designed
with an edentulous space between mandibular right second
premolar and second molar. Occlusal rests were placed on
distal fossa of the second premolar and mesial fossa of second
molar. An undercut depth of 0.01inch was created on the
mesiobuccal surface of the premolar and distobuccal surface of
second molar. Three dimensional finite element model of clasp
assembly was designed and assigned with the properties of two
different materials namely acetal resin and cobalt–chromium in
successive steps. A horizontal bar was constructed between
the occlusal rests of the prosthesis. Later, variable amount of
dislodging force, in increasing order, was applied at the centre
of the horizontal bar and the force at which the clasp arm gets
dislodged was noted with respect to each of the material. The
obtained values were noted and then subsequently analyzed.
Results: The amount of force required to dislodge acetal resin
and cobalt–chromium clasps was found to be 0.02N and 2N
respectively.
Conclusion: The results obtained suggested that acetal resin
clasp exhibited less retentive force than cobalt–chromium
clasps. |
