A thermoplastic pliable resin is softened in warm water then placed on the occlusal surface of the crown to be removed.
The patient is then asked to bite down, compressing the resin block to two-thirds of its original thickness.
The patient is then asked to open the mouth quickly, which should generate enough force to displace the restoration.
This method however, is not very effective and has a risk of damaging restorations on or accidentally extracting the opposing tooth.
Therefore, before using this method, it is important to look at the state of the opposing tooth.
