Abstract
Statement of Problem With the rise of an esthetic demand for a more natural mimic appearance zirconia bridges and frame works are becoming more and more recommended. Having an esthetic strong restoration as zirconia IRFPD is a better option than the aggressive full coverage restoration or a long, painful and expensive procedure as implant retained restoration. Aim of the study to test the effect of cyclic loading and two different surface treatments modalities on the marginal fit of different designs of Inlay retained fixed partial denture cemented with an MPD containing resin cement. Materials and methods 30 IRFPD were constructed from zirconia with three designs [box, inlay box and winged inlay box] n=10. Each group was divided into two subgroups according to the surface treatment [sandblasting, Air borne salinization] n=5. IRFPD’s were cemented and examined by stereomicroscope for marginal adaptation before and after cyclic loading. Results surface treatments and cyclic loading had significant effect on marginal adaptation of IRFPD’s whereas the different design had no significant effect. Conclusion IRFPD is a good alternative to restore missing posterior teeth with application of surface treatments to zirconia and the use of MDP containing cement.
