An accurate reproduction, in the negative form, of an individual’s dentition and other important anatomical structures contained within the oral cavity.
A mould of a person’s jaw made by a dentist before making a denture.
A depression on an organ or structure into which another organ or structure fits.
Mold of a part of the body from which a replacement can be made, especially in dentistry, the mold of the mouth from which dentures are made.
A molding, made in stent, alginate, or other plastic material, of the teeth and gums or roof of the mouth. Plaster of Paris is poured into this mold, which is then reheated and removed so that a plaster model of the teeth and gums is obtained. An impression is used in the construction of dental appliances, such as dentures.
In dentistry, a mould (using a rubber or alginate compound) of the teeth and gums from which a plaster-of-Paris model is prepared. This model provides a base on which to construct a denture, bridge or dental inlay. A similar process is used in orthodontics to make dental appliances to correct abnormalities in the positioning of teeth.
An impression of the upper or lower teeth is created using a flexible substance that solidifies. Once the material has hardened, it can be filled with plaster, plastic, or artificial stone to produce a precise model of the teeth.
