Six months after a baby is born, teeth begin to grow, and by the age of two, a set of nice, neat milk teeth becomes an important organ for children to chew food and take in nutrients. Although “worm teeth” (teeth), trauma serious damage to the milk teeth. But people generally do not mind too much, because the second set of human teeth – permanent teeth will replace the milk teeth. The permanent teeth will accompany people throughout their lives, performing functions such as chewing, speech, and aesthetics. However, in the process of long-term use, due to “worm teeth”, periodontal disease, trauma, tumors, excessive wear and other reasons, resulting in premature loss of permanent teeth, some people even in childhood permanent teeth are destroyed and lost. By the age of forty, many people have lost a lot of teeth. After the age of sixty, the number of patients who have lost all their teeth is increasing. If a second set of teeth is lost, there is one less, and it cannot be regenerated, so the permanent teeth are not permanent. Aging begins with the loss of teeth. At present, although scientific work can not let human beings regenerate a new set of teeth, but the use of bionic principles and methods to develop a successful bionic organ such as artificial dental implants. After the restoration of missing permanent teeth by artificial dental implant technology, not only the shape is realistic and beautiful, but also the patient feels comfortable, the chewing function is restored, and the quality of life is further improved. Therefore, artificial dental implants are the third set of teeth provided by the progress of science and technology.
