This study aims to evaluate three-dimensional changes in die stone models derived from three elastomeric materials after treatment with three disinfectants.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>A 3D-printed master model was used to make 120 impressions with three elastomeric materials: Addition Silicone (Perfit Huge), Condensation Silicone (Zhermack Zetaplus), and Polyether (3M ESPE). Each material underwent four disinfection protocols: no disinfection (T1, control), immersion in 5.25% Sodium Hypochlorite (T2), 2% Glutaraldehyde (T3), and 2% Chlorhexidine (T4) for 10 minutes. Impressions were poured with Type IV dental stone and measured at the canine and molar reference points using a coordinate measuring machine (CMM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Addition Silicone consistently showed the highest dimensional accuracy across all disinfectants. Polyether recorded the lowest accuracy, especially in the control group (T1). Among disinfectants, 2% Glutaraldehyde (T3) preserved the highest dimensional fidelity, followed by NaOCl and CHX. ANOVA and Bonferroni post-hoc analysis revealed statistically significant differences in the canine region for Addition Silicone (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.044), while other comparisons were not statistically significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>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.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/jpbs.jpbs_1194_25","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T16:03:44Z","timestamp":1765814624000},"page":"S3743-S3746","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Dimensional Changes in Stone Casts from Disinfected Elastomeric Impressions Using Coordinate Measuring Machine"],"prefix":"10.4103","volume":"17","author":[{"given":"Chaitra S.","family":"Bulla","sequence":"first","affiliation":[{"name":"Department of Prosthodontics, HKE\u2019S S.
