Effect of Different Techniques for Palatal Denture Base Configuration on Speech Quality in Complete Denture Wearer, HALA M. ABDELHAMEED and MOHAMED E. EL-SAYED
Abstract
Purpose: The purpose of this study was carried out to evaluate the effect of different techniques for palatal denture base configuration on pronunciation of different speech sounds in complete denture wearer.
Material and Methods: Seven completely edentulous patients (4 male and 3 females) selected from out-patient clinic of Faculty of Dentistry, Suez Canal University. All patients were completely edentulous for at least 6 months with no previous denture experience with the chief complaint of missing teeth, inability to chew and speak properly. Each patient received mandibular denture and three maxillary dentures with different palatal denture base configuration. The maxillary denture bases were divided into three groups according to their palatal configuration. Group I maxillary denture with functional (customized) palatal contour. Group II maxillary denture with tin foil reproduction of the patient’s palatal rugea on the palatal polished surface. Group III max-illary denture with cast metal denture base. Acoustic analysis was done using computerized soft ware programme. For each patient, 2 measurements were taken (one immediately after insertion and another 3 weeks later). Sound assessment in-cluded the /s/, /sh/, /th/ and /d/ sounds. Each subject was asked to pronounce certain words which was evaluated or matched in relation to the normal sound as a percentage (%) for matching of (speaking rate ,energy and pitch) to determine the quality of sounds.
Results: There was a highly significant difference between the three groups in favor to reproduced palatal rugea followed by metal palatal one during observation periods.
Conclusion: Based on the results of this study, it could be concluded that, with proper denture construction, the palatine rugae plays an important role in speech pronunciation, as there should be some anatomical landmarks where tongue can recognize and produce best particular sound.
