In the field of implant dentistry, the most widely used implants over the past 40 years are those manufactured from titanium [1], which are still the most popular.

The recent demands for materials without metal alloys in dentistry, together with the increased sensitivity and allergies of some patients, have promoted the development of new materials.

An example of this is zirconia-based dental implants, known as zirconia or zirconium oxide implants. Its biocompatibility and its extraordinary mechanical properties make it suitable for numerous situations. Its main advantage lies in its elasticity which is greater than that of titanium and much greater than that of cortical bone. To avoid overload of the underlying bone from the direct transmission of biting impacts, several materials that can absorb part of this excess force have developed.

One of the prosthetic options lies in the combined use of PEEK restorations with composite coating on zirconia implants due to their physical and mechanical properties and their biocompatibility.
