Measurements of fresh masks were compared to those after molding and re-flattening post-treatment. Dimensions were recorded in superior\u2013inferior (SI) and lateral directions at specific anatomical levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The 3-clamp brain thermoplastic cast expanded 46% \u00b1 7% in SI directions postmolding. Width increased by 63% \u00b1 16% (chin) and 75% \u00b1 10% (forehead). Re-flattened casts showed 25% \u00b1 4% SI reduction and 19% \u00b1 8% (chin) and 26% \u00b1 5% (forehead) contraction in width. The 5-clamp head-and-neck thermoplastic cast expanded 16% \u00b1 3% SI postmolding, with width expansion of 54% \u00b1 15% (chest), 62% \u00b1 10% (forehead), and 66% \u00b1 5% (chin). Re-flattened casts showed 6% \u00b1 3% SI expansion and 26% \u00b1 5.5%, 40% \u00b1 16%, and 37% \u00b1 17% width enlargement at chest, chin, and forehead levels, respectively. The 4-clamp chest\/abdomen\/pelvis thermoplastic casts expanded 3% \u00b1 5% (SI) in 26 casts and contracted by 7.5% \u00b1 2.5% in 2 casts postmolding.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Thermoplastic masks demonstrated acceptable dimensional changes while reusing, with consistent structural integrity and minimal compromise in functionality.
