Abstract

A dental impression is a negative record of the tissues of the mouth. It is used to reproduce the form of the teeth and surrounding tissues. The negative reproduction of the tissues given by the impression material is filled up with dental stone or other model materials to get a positive cast. The positive reproduction of a single tooth is described as a ‘die’, and when several teeth or a whole arch is reproduced, it is called a ‘cast’ or ‘model’.
