How long will the implant last?

I'm 고민이예요 because I have a tooth that needs an implant.

How long can an implant-supported molar tooth last?

I'm worried that since molars are used with a lot of biting force, they might crack or break.

How should I maintain my molar implant?

I'm wondering if I should chew as little as possible since I shouldn't experience too much shock.
