In a sense, it's just a metal spiral nail and a tooth carving on it, which is the price of a modern handicraft-several hundred pieces. However, as far as the history of dental implant is concerned, there have been several years of large-scale dental implant failure, especially in the mid-1990s in China.

At present, due to the improvement of built-in devices, the innovation of surface spraying technology, the refinement of implant system and the revolution of imaging system, the failure rate of implants has dropped below 2%. These are the research results of several generations. The procedure of implant surgery is becoming more and more rigorous, and the work intensity of doctors is becoming more and more intense, just as you can't sell money with strokes and scissors can be a barber.
