Time of Transition from Alginate Impressions and Plaster Models to Digital Models and 3-D Printing

Alginate impressions of the teeth have been used in dentistry for decades to provide quick models of the teeth when needed. Dental practices that have become “fully digital” relying on scans of the dentition, still find alginate impressions poured into plaster models beneficial for a quick replication of the teeth. All dental professionals should know how to recognize and produce excellent alginate impressions in case the need for a quick model arises during this time of transition from quick plaster models to digital model images on the computer that may be printed in three dimensions.
