Impression Material Setting Time
The period of hardening or setting time is the time that a liquid material needs to reach solidity. In dentistry, the setting time plays an important role, especially when it comes to mold and casting materials. All dental materials undergo changes in volume while hardening and are therefore particularly sensitive to faults. Ill-fitting dental work, such as crowns or dentures, can sometimes be traced back to non-compliance with setting times, amongst other factors. Therefore, a conscientious dentist and/or a dental technician will always work with a stop watch, for example when taking an impression. Watch this video to learn why setting time is so important for exact results.

It happened to me that my dentist took out an impression mold too soon and it deformed on the way out... very annoying cause I had to do it all over again!
