| Research Abstract |
As the result of bending test, the bending strengths of NANOZR were higher than those of Y-TZP. This result suggests that NANOZR is more suitable for the clasp of removable partial denture than Y-TZP. On the other hand, as the concern about low temperature degradation (LTAD) of zirconia through the polymerization procedure, the degrees of LTAD were determined by the XRD study. The result of XRD study suggested that the monoclinic content of zirconia was slightly increased, means the zirconia was suitable material for the denture resin. Moreover, as the fatiegue test, the cantilever test was planned to determine the thickness of zirconia clasp.
As the wing type of clasp was difficult to form, bar type was palnned.
