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.
