Abstract
To compare the active tactile sensibility (AST) between natural teeth and implant dentures, and explore the risk factors. To establish a database of normal tactile thresholds of natural teeth, and integrate the results from experiments. 50 patients underwent posterior dental implant restoration. A healthy group was also enrolled as control. Patients were firstly placed in semi-supine position with soothed tension and wore ear pads and goggles. Next, T-scan II digital occlusal analysis system (Tekscan,USA). The test was performed in double-blind way and recorded by the third. Results were analyzed using SPSS software and P value less than 0.05 was considered as statistically significant. Active tactile sensibility showed no statistically significant difference between natural teeth and dental implants among males and females (P > 0.05). However, there was difference between the natural tooth and implant tooth (P < 0.01), and there was also statistically significant difference between the front tooth and the back of the natural tooth and implant tooth (P < 0.01). There is no significant difference in the determination of the active tactile sensitive threshold difference between the implanted tooth and the natural tooth, which could serve as a comprehensive guiding for clinical strategies of tooth implantation.
