Effect of cyclic loading on the fracture resistance of bilayered 3y-tzp and monolithic gradient 5y-tzp/3y-tzp zirconia based fixed partial denture. (in-vitro study)

HIGHLIGHTS

• What: Aim of the Study: This study aims to measure the of a four-unit fixed partial denture constructed from monolithic 3Y-TZP/5Y-TZP compared to 3Y-TZP fourunit fixed partial denture. One stainless-steel master model was designed to simulate a mandibular first Therefore, the objective of this study is premolar and second molar to replace a to evaluate the mechanical behavior and missing second premolar and first molar, fracture resistance of these materials to prepared to receive zirconia fully contoured ascertain their clinical strength under varying four-unit FPD.
