First, the success of a dental implant is based, in addition to proper surgical technique, in which the material which is manufactured with very resistant and also biocampatible so than rejection by the body and amply support the exert pressure on him mastication forces.
In this regard, titanium clearly meets such expectations, but also poses a significant aesthetic problem when the upper teeth and mouth previous line are replaced, as is the possibility that a receding gums occur and consequently You can see a dark line between these and the crown of the prosthesis or implant part expose, spoiling the smile with an appreciable metallic element.
To solve this problem, which can have a significant psychological impact on the patient, it has been investigated with different materials to replace titanium: porcelain, composites, hydroxyapatite, etc. However it has failed them all, either biocompatible or not be very fragile and easily broken.
However, in recent years these investigations have identified a nonmetallic material to be in compliance with all applicable requirements for a dental implant and partly solve the aesthetic problem posed by titanium. This is the zirconia, a ceramic of extreme hardness and strength that was already used for the manufacture of brackets, bolts or stumps to put after a root canal and the construction of bridges and dental crowns.
Zirconium, in addition to strength and toughness, provides some very advantageous characteristics in relation to dental implants:
All this has made today are many dentists who believe that the future of dental implants is zirconium, although it still remains to determine its long-term functionality are still more expensive than titanium implants.

Zirconium, in addition to strength and toughness, provides some very advantageous characteristics in relation to dental implants:
- It is white, very similar to the teeth.
- They are very biocompatible, so they are better tolerated by the gums.
- The degree of osseointegration is less than titanium.
- It does not allow the formation of plaque around.
- It is less allergenic than titanium.
- Resists very well temperature changes.
- Unaffected by the corrosive effect of acids.
- It is very durable, to the point that some professionals offer a lifetime warranty.
