GDC Impression Tray Edentulous Perforated – Upper, Medium

From Garima Dental Suppliers's catalogue

Dental Impression tray Edentulous Perforated is used to take a negative imprint of hard (teeth) and soft tissues in the mouth from which a positive reproduction (cast or model) can be formed. Impression material is of liquid or semi-solid nature when first mixed and placed in the mouth. It then sets to become an elastic solid (usually takes a few minutes depending upon the material), leaving an imprint of person’s dentition and surrounding structures of oral cavity.
