Evaluation of Accuracy of Impression Materials with Different Mixing Techniques

Purpose: To investigate gypsum compatibility and dimensional stability of irreversible hydrocolloid impression materials with three mixing techniques. A comparison between vacuum-mixed, mechanically-mixed and manually-mixed techniques was evaluated for each impression material. Materials and Methods: Three irreversible hydrocolloid impression materials Kromopan 100® (Lascod™), Identic® (Dux dental™), and Jeltrate Plus® (Dentsply™) were tested gypsum compatibility in accordance with ANSI/ADA Specification No. 18 for alginate impression materials. The test for linear dimensional stability was tested in accordance with ANSI/ADA Specification No. 19 for elastomeric impression materials. A One-way ANOVA test was used to analyze dimensional stability at a significance level of (p < 0.05). Conclusion: The vacuum mixing technique facilitates the mixing of irreversible hydrocolloid impression materials and improves the compatibility with gypsum material and reproduces a more dimensionally accurate cast than the other mixing techniques.
