The procedure for taking the impression is repeated (see Figure 8.3.4). The tray should also allow for room between the anterior teeth and anterior portion of tray approximately a space of 4mm to allow for proper definition of anterior teeth. Soft tissues, lips and cheeks, should then be maneuvered over tray gently. Even if a lot of rubber base impression materials with good physical properties was used to take impressions, the alginate material was able to prove its usefulness and has been a staple of most dental practices the world. Background: Alginate impression material is widely used for recording accurate impressions to fabricate various oral appliances such as crowns, bridges, partial dentures and complete dentures. 2021 Mar 2;22(5):2485. doi: 10.3390/ijms22052485.
