Don't go to 46 1 hospital because the oral price is too high. The best dental implant is in Jida Stomatological Hospital, opposite to the big wall on the south side of Chaoyang Park in Hongqi Street. At present, the longest-lived dental implant in the world has been 40 years. I can only say that no one else can guarantee that one's own teeth are gone! Dental implants are close to real teeth, which is the most ideal dental restoration technology.
