Stress distribution and failure analysis comparison between Zirconia and Titanium dental implants

Orthodontic Titanium implants are the most employed and well investigated in literature. In fact, thanks to its mechanical properties and biocompatibility with the human bone, this material represents one of the best solutions to improve the osseointegration process and implant life. In recent years, the attention was shifted to soft tissue integration which has led to a new solution in terms of implant design and material. According to recent researches, metal-free implants, like Zirconia implant, can improve the biological width and accelerate the osseointegration process. Beyond the advantage in biological terms, the use of Zirconia leads to a different mechanical behaviour concerning Titanium, in particular on the cortical bone.
