The investigation went to study on two materials of titanium and Cobalt-chromium alloy for implant.
The safety factor results showed that both materials were capable to carry the applied complex loads.
Materials and Methods The model of the mandible was based on data was obtained from a CT scan images set of 98 slices, with 1mm slice thickness.
Also, maximum equivalent strain in implant extracted and illustrated in Fig. 3 based on five clenching tasks and two materials.

Journal of materials processing technology 199(2008):27-36 3].
Main course of the failure is that the deformation of the materials which near the rivet beyond the certain interlock shape.
The performance of the materials in which near the rivet has a distinct influence on joint.

Introduction With the development of technology and continuous appearance of new materials, the materials of pillow on the market are increasingly rich.
The feather pillow had poor effect compared other materials.
The materials were filled in the pillowcases with 600mm length, and 350mm width, and 50mm height.
There has relatively apparent difference between the pillow materials.
