Results: The accuracy and dimensional stability of impression materials are properties of clinical interest and of fundamental importance, since they correspond to requirements for good adaptation of prostheses or indirect restorations. So recommends the effect of fluoride addition in other concentration. It has the positive properties of alginate, such as short intraoral setting time, hydrophilicity, and easy removal, and also the outstanding properties of a VPS, including crisp detail, elastic recovery, and . Dustless alginate is also present in the market which contain glycol. What is the Ideal Age to get Dental Braces ?? Improper mixing over or under mixing with unset powder left in the improession, Prolonged mixing mixing beyond the mixing time will lead to lack of bond formation leading to tearing of material, Inadequate bulk thin segments tend to tear, in placed without adequate material tearing is common, Premature removal from mouth: Removal before completion of setting time will lead to tearing of the impression.
