Teeth implantation means such a treatmentthat in case ofloss of natural teeth due to dentalcaries, parodontitis or traumas, bio-compatible material is implanted into the location of the lost tooth to serve as artificial tooth root, to which artificial tooth is fixed by screw, shaping the natural teeth.

Permanent teeth will not grow if they are lost. There are many ways to repair permanent teeth.

For one or two vacancies, the former and next tooth will be ground to serve as the bridge; for over two vacancies, partial removable denture is for choice, for full vacancies, a full removable denture is optimal.

Because the bridge is made on basis of teeth grounding, healthy teeth will be damaged.Partial removable denture gives inconvenience in removing and fitting, as well as the foreign sense to the mouth, the teeth for holding the denture sometimes will have to be under overstress, resultting in the shortened life of teeth.Full removable denture is more inconvenient than the partial and its profile and mastication function reduce.significantly.

Once the permanent tooth falls off, it would not grow any more, but now the implanted tooth has been the substitute for it.Once the milk tooth falls off, the permanent tooth would grow; if the permanent tooth falls off, the artificial tooth or implanted tooth can be the choice.

People have been endeavoring to substitute the artificial teeth for lost ones since ancient times, but no significant outcomes had been obtained until Professor Branemark of Gothenburg Medical University in Sweden chanced to find the synostosis of bone and titanium metal, which is a new turning point for the treatment of teeth implantation.

In 1960, Professor Branemark and his colleague researchers inserted the tantalum-and titanium clad chamber into the animal bone in order to understand necessary prior conditions for tissue regeneration after bone damage. When he was trying to remove the Optical chamber to observe the effect after a period of time, he found the tantalum-clad chamber was easier to be separated than the titanium-clad one, which can only be removed at a blob with the surrounding bones. They named such combination of bone and titanium as Osteointegration (synostosis).

Implantation teeth ought to be made of materials that are very compatible with human tissues and alveolar bone.

Titanium, Zirconium, Niobium and HA and the like are very compatible with human body, but when taking into account strength and combining capacity with bones, titanium is the justified as the most stable material for implanted tooth. After long-term experiments, titanium implanted tooth is proved to be the human-safe material and now it is widely used in the fields like orthopedics and neurosurgery etc.

Particularly， since special processing method now has been developed to treat with the implanted tooth surface, it has increased the success ratio of the implanted tooth.
