Is it possible to attach a permanent lower retainer to #27 if it's a crown and part of a bridge? And if so, how? (Photo)

Can a permanent retainer be successfully attached, bonded (whatever however secured) to a Crown #27 on a bridge ? 22 is a adult tooth. , 27 crown,28 Pontic, 29 crown bridge. SEE DIAGRAM PHOTO How is that attached, what is used to adhere it ? What are the success percentages that it will stay attached ? Thank you.
