Titanium, precious metal alloys and ceramics, such as zirconia, are commonly used in long-term dental applications. Each material has specific advantages. Recently, other materials have established themselves in the dental industry: fibre-reinforced thermoplastics, such as Polyaryletherketone (PAEK).PEKK is considered as the highest member of the Polyaryletherketone (PAEK) polymer family, this family of polymers is distinguished by its strong damping power and its highly biocompatible character, in addition, off-white color gives it a major aesthetic benefit too. It is having a density (less than 2g / cm3), resistance to pressure (between 200 and 300 MPa) and a modulus of elasticity which is comparable to that of dentin, enamel or bone. This relative flexibility and lightness are all particularly valuable from a clinical point of view for implant restorations. In this domain, we can say that PEKK can bring about revolutionary changes in restorative dentistry, in this review with limited available data on PEKK an attempt is made to evaluate the various mechanical properties of this material.
