RESUMEN
La remoción de una impresión tomada con un material viscoelástico genera una serie de tensiones en la unión elastómero adhesivo cubeta. Si el adhesivo no es capaz de contrarrestar dichas tensiones, se producirá una distorsión permanente de la impresión y por consiguiente el modelo resultante no será exacto.
La presente revisión bibliográfica tiene como objetivo analizar la influenciaque tienen las cubetas y los adhesivos en la exactitud de impresiones tomadas con elastómeros.
Palabras clave: Cubetas, adhesivos, exactitud, materiales elastoméricos.
ABSTRACT
The removal from the mouth of an viscoelastic material, develops stresses in the bulk of the impression material, the adhesive which adheres it to the tray, and the tray. If the adhesive is not able to withstand thestresses, permanent deformation will occur and the model obtained from it, will not be accurate.
The purpose of this paper was to review the literature in regards to the variables mentioned above.
Key words: Trays, adhesives, accuracy, elastomeric materials.
