The longevity of implants depends on several factors:
The professionalism of the doctor who placed them.
The quality of the implants used.
The standing of your health.
How gentle you are with your artificial teeth.
The proper care of your denture.
In general, depending on the company you choose, implants can last anywhere from 5 to 20 years.
Keep in mind that damage to your denture does not mean you need to replace the entire system. If the pins implanted in your jaw are in good condition, your dentist can install a new denture on them. And it will cost several times less.
