Abstract

|
In this study, we used the AnyCheck device to determine the effect on the implant stability test (IST) of different prostheses. The purpose of this study was to safely measure the stability of the implant and to determine whether the IST can be used even after the prosthesis cementation. Fifteen implants were placed on the artificial bone block.
Prostheses were classified into five groups: healing abutment, ready-made abutment, polymethyl methacrylate (PMMA), monolithic zirconia, and PFM. For PMMA, monolithic zirconia and PFM were produced using the same design within the computed-aided design/computer-aided manufacturing system. Results of the analysis, showed that, in all groups, IST had significant reliability, and a difference was noted based on the type of prosthesis. There was no significant difference in IST between the ready-made abutment and the healing abutment, but the average IST decreased in PMMA, and the average IST increased in monolithic zirconia and PFM. Each group’s IST showed a consistent tendency according to the type of prosthesis. Thus, the IST can be used for the evaluation of implant stability, even after prosthesis cementation, as well as for the determination of the timing of implant loading. Because the change in IST was correlated with the hardness and elastic modulus of each type of prosthesis, additional research on the physical properties of each material is required.
