I have been asked many times this question about Wisdom teeth When to have my Wisdom Teeth removed? A dental impression is a negative imprint of hard and soft tissues in the mouth from which a positive reproduction, such as a cast or model, can be formed. Alginate impression materials are used to capture a range of dental impressions because when properly used they provide highly.
