FilayDent Wamkey is a set of three instruments designed to remove crowns quickly, easily and without damaging the margins or the bulk of the crown. The clinician drills a small horizontal hole through the crown and enlarges it until seeing the level of the cement layer. Then a tunnel is drilled through this window until reaching the centre of the preparation.
Then the WAMkey, which has an oval profile, is inserted into the hole and rotated to raise th crown along its vertical axis. Crowns and bridges can be reused after any underlying treatment has been completed. When replaced, the access hole is simply sealed with an appropriate shade of composite.
WAMkey 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.WAMkey disassociates the crown from its abutment without applying ANY traction or tensile forces, or sideways movement. Wamkey doesnt pull the crown off, it actually PUSHES it off from underneath. Thus, there is no risk to fracture the tooth or to remove the build-up underneath.
So why take risks ?
Outdated, traditional style crown pullers exert dangerous, heavy tensile loads on the ligament, and waste much of the removal force stretching the ligament and causing unnecessary patient trauma, and regularly damage or even extract the preparation….got your lawyers number handy?
WAMkey is totally risk free !

WAMkey disassociates the crown from its abutment without applying ANY traction or tensile forces, or sideways movement. Wamkey doesn’t pull the crown off, it actually PUSHES it off from underneath! PERFECT! Thus, there is no risk to fracture the tooth or to remove the build-up underneath.
WAMkey exerts only a natural compressive pressure on the supporting tooth, which gradually increases until the crown is easily removed – without impact, damage or discomfort.
WAMkey preserve’s the crown or the bridge to allow temporary or permanent re-use.
The main parts of the crown (margins, occlusal face and contact points) are preserved undamaged.
Additionaly, in many situations, the initial window can be cut with the CMV bur on the lingual face. Why is this important ?
Because after its removal, the prosthesis retains all its mechanical and aesthetic properties. You can now either make a small instant composite repair, or refer to the technician. Thus, a provisional or permanent reset is possible.
The pressure on the filling is particularly low, so that you can dismiss any risk of leakage
Why waste money ?
With outdated traditional methods, the removal process can be time consuming and expensive, and the result uncertain. With WAMkey, your precious time is saved, because the entry window made in the crown is very small. By avoiding cutting the whole crown off, you also save your rotative materials (contra-angles, hand-pieces and drills…). And don’t forget that in many situations you can also reset the crown provisionally or permanently. Bonus !
REMOVE YOUR CROWN BEFORE ROOT CANAL TREATMENT !
Stop doing your root canal through the crown. WAMkey allows you to remove the crown in 1 or 2 minutes and in some cases, less than a minute.
Once the crown removed, you have a easier access to the root canal, you can make an easier repair of the crown, and above all, you have an opportunity to make a far better diagnosis because you can visualize everything under the crown.
HOW IT WORKS ?
Firstly, 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.
Secondly, drill a thin horizontal window in the crown.
Enlarge this window until you can see the cement layer through the window.
Then, after having checked that the slot is at the cement level, deepen the hole until it reaches the centre of the tooth preparation.
Slightly extend the hole to form an horizontal rectangle.
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).
