Abstract

The study was performed to assess the magnitude of biting force
For patients with two types of cad cam esthetic clasp dentures (modified and unmodified Bre-Flex denture base material).
Methodology: A total of five mandibular Kennedy class I partially edentulous male patients were included in this study. All patients received two successive esthetic clasp removable partial dentures (modified and unmodified Bre-Flex). For each patient the mean biting force was measured at the time of insertion and after 2 months of using the dentures with one-month tissue rest between the two types.
Results: One way ANOVA test was conducted to assess the significance between the two RPD types at time of insertion and after two months of use, the data revealed that the mean biting force for the modified group at time of insertion was 0.1172+0.135 and after two months was 0.1264+0.3 with no significant differences. The mean biting force for the unmodified group at time of insertion was 0.108+0.0924 and after two months was 0.1236+0.104 with P value 1.00, indicating no significant differences. There were no statistically significant differences between the two groups in relation to the patient's maximum biting force. (P value was 0.22).
Conclusion: For each group (modified and unmodified partial denture base materials), there was no significant difference regarding the mean biting force at time of insertion and after two months of use. There were no statistically significant differences in relation to the patient's maximum active biting force between the two groups. (P value was 0.22).
