Impression Technic, Dental
Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of Paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted.

Imprinting
Developmental learning of a type first brought to scientific attention in studies of animal behavior by ethologists. Imprinting takes place in a given species when behavior phyletically programmed into the nervous system of that species requires a matching socioenvironmental stimulus to release it, when the matching must take place during a critical or sensitive developmental period (not before or after), and when, having occurred, the resultant behavior pattern is unusually resistant to extinction. In human beings, native language learning is a manifestation of imprinting.

Imprinting (Psychology)
A particular kind of learning characterized by occurrence in very early life, rapidity of acquisition, and relative insusceptibility to forgetting or extinction. Imprinted behavior includes most (or all) behavior commonly called instinctive, but imprinting is used purely descriptively.

The variable phenotypic expression of a gene depending on whether it is of paternal or maternal origin, which is a function of the methylation pattern. Imprinted regions are observed to be more methylated and less transcriptionally active. (Segen, Dictionary of Modern Medicine, 1992)
