Retention force of T-bar clasps for titanium and cobalt-chromium removable partial dentures.
The objective of this study was to evaluate the retention force of T-bar clasps made from commercially pure titanium (CP Ti) and cobalt-chromium (Co-Cr) alloy by the insertion/removal test simulating 5 years use. Thirty-six frameworks were cast from CP Ti (n=18) and Co-Cr alloy (n=18) with identical prefabricated patterns on refractory casts from a distal extension mandibular hemi-arch segment....
متن کاملThe abrasion of dental composite by cobalt-chromium clasps.
In cases where there are no suitable natural undercuts on the teeth which can be used to provide clasp retention for a partial denture artificial undercuts can be created by the application of a composite filling material. An in-vitro investigation was undertaken to assess the surface integrity of three different composite restorative materials following repeated cycles of movement of cobalt-ch...

متن کاملComparison between Acetal Resin and Cobalt-chromium Removable Partial Denture Clasps: Effect on Abutment Teeth
Fabricating an esthetically pleasing removable partial denture while avoiding the unsightly display associated with conventional clasp assemblies presented a challenge to dentists. Among other techniques, this could be done using acetal resin clasps as simple and effective means of improving removable partial denture esthetics.1 Patients often cite lack of retention and poor esthetics as reason...
متن کاملAn in vitro comparison of retentive force and deformation of acetal resin and cobalt-chromium clasps.
STATEMENT OF PROBLEM The use of metal clasps on anterior teeth may cause esthetic problems. Recently, acetal resins have been used as an alternative tooth-colored denture clasp material to improve esthetics. However, there are few studies to support acetal resin use. PURPOSE The purpose of this in vitro study was to compare the retentive force and deformation of acetal resin and cobalt-chromi...
