| WAMkey's
patented unique, gentle separating action allows the crown to follow
the path of least resistance. In fact, it will look for the weakest
point and gently de-bond the cement. Without pain to your patient,
and with no risk of damage. |

STEP
1
First, locate the most accessible spot on the crown.
The goal is to estimate the cement layer level between the occlusal
surface of the abutment and the inner side of the crown itself.

STEP
2
Second, drill a thin horizontal window in the crown.
Enlarge this window until you can see the cement layer through
the window.

STEP
3
Then, after having checked that the slot is at
the cement level, deepen the hole until it reaches the centre
of the tooth preparation

STEP
4
Slightly extend the hole to form an horizontal
rectangle

STEP
5 Finally,
introduce the key down to the bottom of the slot and make a simple
rotation on the handle.The crown is removed! In many cases, you'll
be fooled into thinking that the WAMkey is meeting no resistance;
even the patient may feel nothing at all. So watch attentively
and ask your patient to listen carefully...
It usually takes between 1 and 3 minutes to remove each crown.
In specific cases (for example when removing ceramics or crowns
on posts), the process may take a bit longer ( 4 to 8 minutes
at the most).
