Ceramic implants:the state of art
A multitude of biomaterials have been used for the production of implants through the years. Titanium or titanium alloy have been regarded as the 'gold standard' for years. However, potential risks and disadvantages regarding biocompatibility and aesthetics have also been reported for the use of titanium in dental implantology. As such, there is need for an alternative material. Zirconia may be regarded as a possible alternative. It is a ceramic with high fracture toughness and other positive qualities, such as beings metal-free, biocompatible, and white, which is aesthetically desirable. Short-term study results of contemporary zirconia implants are promising and comparable to titanium implants. Nevertheless, the material is relatively brittle and susceptible to surface defects. However, no long-term clinical results exists and possible complications are unknown. Long-term clinical research is needed before zirconia implants routine use may be endorsed.</p
