Resumen

Objective: This study examines how palatal vault depth, mechanical anchoring, processing techniques, and denture cleanser immersion affect the posterior palatal adaptation of acrylic denture bases. Materials andMethods: Forty-eight PMMA denture bases were fabricated using either compression or injection molding. They were categorized by palatal depth (shallow, medium, high) and the presence or absence of anchoring holes. Specimens were immersed in four solutions—distilled water, 1% sodium hypochlorite, 2% chlorhexidine, and Kin® effervescent tablets—for 3, 10, 30, or 60 days. Digital gap measurements were analyzed using two-way ANOVA and Tukey’s HSD tests (α = 0.05). Results: Adaptation was significantly affected by palatal depth, anchoring, processing method, and immersion time (p < 0.05). Different gap distances were observed across palatal depths, with anchored specimens demonstrating better adaptation. Injection molding provided greater dimensional stability over time than compression molding. However, cleanser type did not significantly influence adaptation (p > 0.05), regardless of immersion duration. Conclusion: Posterior palatal adaptation is mainly influenced by fabrication method, mechanical anchoring, and immersion time, while cleanser type has minimal effect. Optimizing these factors can improve denture fit and longevity.
