Abstract

Despite of the successful clinical performance of implants, it is still lacking of the knowledge of changes in implant occlusion. The purpose of this study was to evaluate the changes of infraocclusal contact after clinical occlusal function of implant. Twenty patients(38 implants) were recalled during 10 months after placement of implant prosthesis. Occlusion changes were investigated at placement, placement 1 months, 4 months and 10 months serially with silicone bite material and T-Scan II sensor. Bony changes were also evaluated with periapical radiographs. The changes of silicone thickness and T-Scan II sensored areas were statistically analyzed with repeated measured ANOVA and the Scheffe's post-hoc test at the 95% significance level. The following results have been made based on this study: 1. Alveolar bone loss was within 0.20mm and it was generally concluded within physiologic level. 2. There were no statistically significant differences in the thickness changes of silicone material at 1 month and 4 months of occlusal function. However, there was statistically significant difference at 10 months of occlusal function (p<0.05). 3. There was no statistically significant difference in changes of occlusal contact area in T-Scan II at 1 month and 4 months of occlusal function, but there was statistically significant difference at 10 months of occlusal function (p<0.05). Conclusively, as time goes by, implant occlusion to be formed infraocclusion was to be far close and increased occlusal contact. However, it was not observed destructive bone resorption in periapical radiographs and any other side effects.
