A procedure capable of characterizing, visibly, with different images, writing, initials or numbers, and invisibly, with passive emitting materials, the surface of natural or artificial teeth. The required decorative or emitting effect is obtained due to the fact that the extremely thin decoration, usually a decalcomonia or other printed support, or the plate or emitting film rests between two layers of photopolymerized, transparent bonding material and that its surface may possibly be covered by a further layer of transparent compound. Both the application and the removal of the aforesaid images, once applied, cause no damage to the tooth. |
