In this work composite materials, based on quartz fibers posts and adhesive resins, were employed with the aim to restore damaged teeth.
Their transparency meet the need of modern aesthetic dentistry, allowing repairs in the frontal teeth and the replacing of the metal materials.
A catastrophic brittle pull-out fracture was found for both materials.

Moisture property of polymer is condition that melt spread out on bonding interface of materials [9].
Experimental Materials and Instruments.
To ideal brittle materials damage, G (interface fracture energy) equal to cohesive energy.
In one side, melts polarity is first effective element when melt spread out on strong polarity materials, such as Fe.
