Comparative Evaluation of Masticatory Performance and Swallowing Threshold of Patients with Mandibular Tooth Supported Overdenture, Implant Supported Overdenture and Natural Dentition- A Clinical Study.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 3
Abstract
Background and Objectives: There are number of studies that have reported the benefits of over denture treatment, which includes TSO (tooth Supported Overdenture) and ISO (Implant Supported Overdenture), over CCD (Conventional Complete Denture) treatment. However there are very few studies that have compared the masticatory performance of the TSO and ISO. Therefore, this study was conducted to analyze and compare the masticatory performance and swallowing threshold of ISO, TSO and natural dentition.Methods: Total of 120 patients were screened out of which 30 subjects of age group 40-60 years were selected and divided into three groups .Masticatory performance was evaluated using objective multiple sieve gravimetric method. The weights of the coarse particles of the test food on each sieve after a twenty chewing strokes was measured. Swallowing threshold was evaluated by recording the number strokes and the time taken by these three groups to reach the moment when the subject felt the urge to swallow the test food. All statistical analysis was performed using IBM SPSS 19.0 Software.Results:Masticatory performance and swallowing threshold of TSO and ISO showed no significant difference (p > 0.05). Significantly higher masticatory performance and lower swallowing threshold was observed when ND was compared with TSO and ISO (p <0.05). Conclusion: Within the limitation of the study, it was concluded that the masticatory performance & swallowing threshold of T.S.O & ISO was comparable. The masticatory performance of natural dentition was significantly higher than TSO & ISO group. The swallowing threshold of ND was significantly lower than TSO & ISO group.
