Evaluation of Dimensional Changes in Stone Casts from Disinfected Elastomeric Impressions Using Coordinate Measuring Machine

Disinfection does not adversely affect dimensional stability of elastomeric impression materials. In total, 2% Glutaraldehyde demonstrated superior preservation of accuracy, particularly with Addition Silicone. Polyether showed the most dimensional variation, suggesting its hydrophilic nature may compromise stability post-disinfection. Clinical implication suggests selecting Addition Silicone with Glutaraldehyde for optimal results.
