Removing edentulous impression trays

Firstly, it is useful to mark the vibrating line using an indelible marker like thomspon sticks so you know if you have over or underextended the tray. this will transfer to the 2nd impression and ensure that the correct extension is made of your wax rim. Suction can be quite strong with these impressions and to ease removal of the tray, push the handle tissue ward to allow the posterior section of the tray to disengage first and this will break the seal.
