Abstract：Objective:To describe a duplicating technique for complete denture and evaluate the effect of different palatal bases on the speech sound in patients wearing these dentures. Methods:In the study, the dentures were made by the copy denture technique, and divided into a pure Titanium group, a PMMA group and a cobalt-chormium group. Using the patient's self-judgment and the measurement of Chinese intelligibility, the voice features of the complete dentures with different bases were tested when denture was placed in the mouth at the beginning. Results: The data of Chinese intelligibility showed significant differences between the metal groups and the plastic groups at the beginning of placement. Significant differences were found between the metal groups and the plastic groups (P<0.05), while the complete denture with titanium palatal plate was shown to be similar to the cobalt-chormium group. Conclusion: It is the thickness of the denture base other than the actual material that is likely to have greater impact on the recovery of patient’s phonetic function.
