Abstract
Implant supported FPD provide a reliable treatment option for partially edentulous patients. All-ceramic bridges exhibit outstanding esthetics and excellent biocompatibility. Continuous development of both ceramic materials and fabrication techniques allowed for the introduction of new all-ceramic systems. The mechanical properties of these systems have to meet the requirements needed to withstand the stresses and strains that can arise in posterior regions in the oral cavity. The current study evaluated the effect of connector design, mainly the radii of gingival embrasure angel which where 0.5 and 1 mm, and the veneering techniques, mainly press- on and CAD-On, on the biomechanics of implant supported three units posterior all ceramic FPD, the relative effect of the two zirconia framework designs and veneering techniques were compared using two methods namely, mechanical loading test, and 3D numerical finite element analysis. The following materials were used in the current study: Zimmer Dental Implant fixtures. Zimmer Dental Implant abutments. IPS e.max ZirCAD blocks. IPS e.max CAD block. IPS e.max ZirPress block. Self-curing epoxy resin. Finite element software package
