Was to describe a step-by-step protocol for the use of an individually manufactured silicone stamp for the restoration of class II carious cavities. Restoration of a tooth using the «silicone key» method in carious defects on approximal surfaces has a number of features. Liquid cofferdam was used as a material for the manufacture of an individual occlusal stamp. This article presents clinical illustrations and a step-by-step description of the technique. When using this technique, the occlusal surface of the restoration fully corresponds to the occlusal surface of the tooth before treatment, that is, the anatomy and functions are restored in full. In addition, the modeling protocol is simplified, and the working time is reduced, which is undoubtedly more comfortable for the patient. When monitoring occlusal contacts after work using the technique of an individual occlusal stamp, the restoration is in perfect anatomical and functional interaction with the antagonist tooth.
