Comparison of titanium and FGM dental implants with different coating types

Abstract Despite their proven record in promoting osseointegration, titanium and titanium alloys present certain other challenges to providing an optimal dental implant. Titanium and suitable titanium alloys have a higher stiffness than human bone, and therefore dental implants formed from such materials absorb most of the forces of mastication. This can lead to a phenomenon known as a stress shielding of the surrounding bone. A variety of bioceramics have been developed and used in different implants due to their excellent biological performance. However, only a few of them have been used in clinical applications, especially in low load bearing implants, due to their poor mechanical strength. Little existing research has been reported for the design of dental implants made of FGM materials. However, many researchers have studied the effect of improving the dental implant surface by coating its surface with different materials including functionally graded materials (FGM). On the other hand, the effect of...
