TESTING OF ZIRCONIA FPD FRAMEWORKS FOR FIXED PROSTHESES: MODEL DESIGN AND EVALUATION OF FRACTURE LOAD.

In our previous test model, the abutment teeth and the model base were printed with resin and bonded with a polyether material. Some abutment teeth were fractured during the mechanical load test. Therefore, the aim was to develop and evaluate a new model under mechanical loading until fracture with zirconia FPD frameworks.

Application of a standard autoclaving protocol does not harm structural integrity of two-piece zirconia abutments under detachment force testing.

Objective: Aim was to assess the influence of a standard autoclaving protocol on the retention of zirconia abutments glued on titanium bases in two-piece implant abutments.

Materials And Methods: Twenty-four CAD/CAM-generated zirconia abutments were adhesively cemented on prefabricated titanium bases. Before mechanical and thermal aging, the specimens were divided into two groups.
