Compared with titanium, porous tantalum, whether used as an alloy or as a coating, has a porous structure and mechanical properties similar to natural bone, as well as good biological activity and low cytotoxicity.

At the same time, the special structure of porous tantalum promotes bone growth and forms a special bone-implant interface (bone penetration), which can enhance the stability and function of implant teeth in bone tissue.

Therefore, biometallic materials based on porous tantalum have broad prospects in the application of dental implants.

Because of its open porous structure, it can be used to implant the idea of drug administration to improve the impaired bone healing ability of abnormal jaw metabolism.

However, dental implants based on porous tantalum face some clinical challenges such as whether to cause peri-implant inflammation. A large number of clinical trials are needed for the comprehensive evaluation of porous tantalum based dental implants.
