How long do implants last? Also, how to extend their lifespan? ㅠ

How long is the lifespan of an implant?
When searching the internet, some say it is about 10 to 15 years, and
I'm not exactly sure because I've heard that some people use it for over 20 years!

I want to know what factors influence the lifespan of dental implants.
Additionally, the initial condition during implant placement or
I wonder if the success rate of the surgery also affects the lifespan of the implant.

How should I care for my implant to use it for a long time?
I would like to know if there are any particular points or habits I should pay special attention to in my daily life.

Are there any differences from regular dental care?

For example, I am curious about which foods to avoid and how often I should visit the dentist regularly. Also, if there are any professional care methods or auxiliary devices provided by the dentist, please recommend them.

Actually, I have about dental treatment.

Because of the fear, I try not to visit as often as possible.

I want to maintain my dental implants well.

But I know that consistent management is necessary in reality.

I think there are many people who have the same concerns as I do.

I would like to hear how others are managing their implants and also hear about their actual experiences.

Please tell me about the lifespan of implants, haha.
