This study was carried out to evaluate different denture base designs on phonetics with maxillary complete denture. Twenty-one completely edentulous patients receive conventional complete dentures. Phonetics was assessed by articulation test after one month (adaptation period). Removal of palatal coverage was done and application of denture adhesive with adaptation period one month and phonetics was re-assessed Another complete denture with metallic denture base was duplicated and after adaptation period, Phonetics was evaluated by articulation test.Results reveal that the degree of articulation accuracy while pronouncing letters (ص, س, ز) with palate-less denture is better than neither that of conventional acrylic complete denture nor that of complete denture with metallic denture base The study concluded that the phonetic differences appeared on the consequence of modification of resonance room of oral cavity according to denture base design and material.
