What is the difference between dental implants and real teeth?

Dental implant is a kind of root into the alveolar bone inside, it is not a real root, is made of titanium alloy material, can exercise the function of the root. Root implant nail is porcelain teeth above, so essentially implant teeth are dentures. Because it is dentures, so do not eat too hard things, pay attention to oral hygiene or cause implant nail loose. And real teeth are normal teeth, can be used normally.
