Objective:
To evaluate clinic adaptive effect of speech articulation of patients before and after restoration with complete denture.
Methods:
Before and after patient's restoration at the beginning and then at 1 week, 2 weeks, 4 weeks and 8 weeks, the patient's self-judgement and the measurement of Chinese intelligibility by speech pathologist were used to analyse the regularity of speech articulation of edentulous patients restored with complete denture.
Results:
At the beginning, the patients in two groups all felt uncomfortable of using denture. After one week, patients using metal base denture adapted well, but patients using plastic base denture needed 2 weeks to adapt. The data of Chinese intelligibility showed significant difference between two groups after using denture 1 week (P<0.05). In metal base group, there was significant difference before and after using denture a week (P<0.01). The plastic base group showed this change after two weeks.
Conclusion:
Patient's phonetic function recovered quickly when the thickness of the base reduced and palatal rugae of the denture base restored. The chinese intelligibility of them was better.
