Hello, this kind of advertisement may be a cover. Nowadays, many places will advertise with the words "public welfare" or "free" in order to attract people's attention. But for dental implants, it is free. It should be impossible. I had previously helped the elderly at home learn about dental implants. The cost of dental implants is not cheap. The general price ranges from a few thousand to more than 10,000. You said that if everyone could get one for free If there are no quota for dental implants, then the dental hospital will be short-changed.
