Connection of functional quality of partial removable dentures and the degree of patients’ phonetic adaptation

Introduction. Phonetic adaptation is a complex biological phenomenon with a highly individual course, depending on the patient’s motivation to use prosthesis, on the functional quality of removable dentures. The aim of the study was to estimate phonetic adaptation in patients with partial dentures, connecting it to alteration in speech quality and dentures functional value.
Materials and methods. We examined some peculiarities of phonetic adaptation in 50 patients with removable dentures (50 patients with natural dentition were invited for the control group). The standardized evaluation protocols (12 speech quality determining parameters) were developed separately for Latvian and Russian native speakers. 500 speech video samples were recorded and analysed according to pre-established guidelines. The connection of speech quality and the functional quality of the dentures was assessed. Statistical analysis was performed using SPSS 20.0. P values equal to or less than 0.05 were considered to be statistically significant.
Results. In patients with appropriate functional quality of removable dentures distorted speech production was detected in 25% (pk=0.008) cases and in patients with inappropriate functional quality of the prosthesis – in 40% (pk<0.001). Patients with appropriate dentures functional value were satisfied with their speech performance in 96% (pk=0.674), in the group with inappropriate dentures functional value only 59% (p<0.001) rated their speech quality positively.
Conclusion. Phonetic adaptation to removable dentures depends on the patient’s individual adaptation capacity, prosthetic design and functional value. Thus statistically significant correlation between removable partial dentures functional value, duration of usage and the degree of patients’ phonetic adaptation (p<0.001) may be considered to be confirmed.
Key words: phonetic adaptation, removable partial denture, speech quality, patient’s satisfaction with prosthetic rehabilitation.
