Question regarding a cap on front tooth. Original crown broke off after 30+ years?

Recently I had two pins cemented in to hold my front tooth/cap in place. How long do those typically last? I had a crown on that tooth for over 30 years and it broke off (tiny piece of tooth that was still there snapped off) and the dentist did a build up and put in two pins to cement the cap back into place. Just would like to know how long I can plan on this lasting before I have to do something drastic as a replacement. Such as an implant, etc. Thank you.
