MAXILLARY ALGINATE IMPRESSION RATIO HOW TO
How to cite this article: Choudhary S, Sivakumar I, Buzayan MM, Choudhary P. Keywords: Deformation resistance, dimensional stability, extended pour alginate However, for better results casts should be poured immediately. Conclusion: Clinically acceptable casts can be generated by the double pouring of new generation alginates. However, percentage dimensional change was within clinically acceptable limits. A significant difference was found between standard die and second poured casts of both alginates after 24 h. Results: No significant difference was found between standard die and second poured casts of both alginates after immediate pouring. Casts were scanned with a three dimensional model scanner and compared with standard die. Ten impressions of each type of alginate were stored wrapped in damp paper towel and stored in zip-locked bags, and two sets of cast were generated after 24 h. Two sets of casts were generated from 10 impressions of each type of alginate immediately. Methodology: Forty impressions were made of a maxillary dentulous model (standard die), using two types of alginate (Hydrogum 5.0, Cavex Colour change).
Aim: This study aims to evaluate the dimensional stability of casts generated from first and second pour of two different types alginate purported to allow multiple pour and remain dimensionally stable after storage. However, there is a lack of sufficient scientific evidence in this regard. Background: A new generation of smart alginates have been developed claiming to have good dimensional stability and deformation resistance.
