I have been using WamKey® for many years and teach the simple technique for crown and bridge removal on my courses.
Three easy steps:
1. Cut a small buccal or lingual window to accommodate the WamKey®.
2. Cutting along the cement line, go as deep as the centre of the occlusal plane
3. Do not use a lever action, simply rotate the Wamkey 1 and the crown uncements
Should the WamKey® 1 rotate within the core, use the slightly larger WamKey® 2. You will only sometimes need to go up to WamKey® 3 but do have it just in case
WamKeys are robust and autoclavable so if you buy a set (WamKeys 1,2 and 3), it will probably last your career.
I don’t think there is a better, more reliable or predictable method for premolar and molar crown removal, it’s a life changer!
