Dental lab gypsum materials are used to create highly accurate model from a physical impression of a patient's teeth. The models are fabricated by pouring the gypsum material into the impression and allowing it to harden. There are a wide range of gypsums used in dentistry with different properties depending on how the models will be used. Some gypsums are ideal for use in sectioned models and dies, others are designed to be scanned for use in CAD/CAM dentistry, while other model materials are designed for use in vacuum-forming orthodontic appliances, mouth guards or other appliances. It is important to be sure your gypsum is properly set and be sure to properly label your models and dies so they stay with the correct case.
