Bonding Modified Stamp Technique

Direct posteriors - Tips and tricks
13 Nov 2017

Everybody knows the so called ” stamp technique “, which is a modern and fast way to reproduce the original anatomy of the tooth we need to restore, if we start from a perfect and sound morphology. In the original technique to avoid the sticking of the stamp to the composite we used to use a piece of teflon PTFE that must be put between the stamp and the restoration. But this leads to have some problems, among them: not perfect replication of the morphology, no possibility of removal of the excess immediatly before light curing, no possibility to sculpt back the morphology before lightcuring.

So the author proposes a new technique that allows to remove the stamp while the composite is still plastic, to remove then the excess and to refine the sculpting of the material, just using a little amount of bonding on the stamp. Whit this there’s no more the need of the teflon tape and the stamp won’t stick to the material at all.

The stamp is applied directly on the composite

It is removed while the composite is still plastic, without any problem of stickness for the presence of the bonding on it

Then the shape and morphology can be improved due to the fact that the composite is still plastic

The stamp’s used as the same in the neighbour teeth

Conclusions

A simple tool can help us in saving time and doing everyday routine in a fast and precise way. Now it’s even better and faster.
