This study aimed to determine the effect of duplication of palatine rugae on the acrylic denture base on speech quality in patients with a complete denture. This study was conducted on ten subjects. All subjects used full denture with two kinds of maxillary dentures. The sound resulted from each subject taken before using complete denture, when using the denture without duplicating the palate rugae and when using the denture with duplication of palatine rugae. The values obtained were then processed and analyzed by the Kruskal Wallis and Mann-Whitney tests. The sound quality produced showed a significant value of 0.000 in the pronunciation of letters / t /, / d /, and articulation in the Kruskal Wallis test (p <0.05) in each group assessed. The Mann-Whitney Post Hoc test also obtained a significant value (0.000 with p-value <0.05) for comparison of the use of full denture without duplication of palatine rugae and a complete denture with duplication of palatine rugae. This study concluded that denture wearers' speech quality with duplication of palatine rugae was better than the one without palatine rugae.
