Abstract Currently, titanium dominates the dental implant materials due to its strength and bio-inerrability.
New implant materials are proposed, the most promising new implant material is perhaps functionally graded material, for short FGM [2, 3].

Composite materials are made with different materials that are physically and chemically different alienated by interfaces.
The compressive strength of the hybrid composite was approximately the same as that of the matrix materials, however its impact strength was slightly higher than that of the matrix material [16].
