Tantalum has been used as an implant material in the repair and treatment of patients with missing teeth. With the development of science and technology, porous tantalum has also been applied in the implant field. Because of its excellent mechanical performance, biological properties, with bone tissue equivalent elastic modulus, high coefficient of friction, can provide good bone implant combined with early and stability, and is referred to as the trabecular bone implant, it has with bone tissue equivalent modulus of elasticity (between cancellous bone and compact bone) makes the implant teeth in the mouth of the long-term functional load force scattered into the surrounding bone, avoid the stress concentration.

Experiments have shown that traditional implants can absorb 30% of the load energy in the process of dental force loading, while porous tantalum implants can absorb 50%-75% of the load energy. The high friction coefficient enables it to have good initial stability in the implant implantation process, so as to improve the bonding rate of the implant teeth, especially the implant patients with poor bone quality.

At the same time, professor liu hongchen put forward the concept of drug administration of artificial dental implants, which is expected to improve the healing ability of bone damaged in the state of bone metabolic diseases on the basis of promoting the bone union of implant through drug loading in porous tantalum artificial teeth.
