Dental lab plasters are ideal for pouring study models, and other general dental models. These plasters are easy to mix and pour to create smooth models that are easy to work with. Different plasters feature different setting times, and while the setting expansion is usually low for plasters, it's a good idea to test out a new plaster to make sure it provides the results you desire.
