Yes Bill the partial denture is a little bit difficult to remove initially and u  learn the tectnique to remove it with practice.You can start with it and as u will wear it with time u will get used to removing and placing it in mouth.

You need 2 hands to remove it other wise if u remove with 1 hand then the other side does not allow the denture to move out but with time u may learn to do it with 1 hand also and u do need a rocking motion while removing the denture................for more info refer the link.......................http://www.identalhub.com/forum_retention-of-lower-partial-dentures-2385.aspx
