Comparative Evaluation of Stress Distribution around Various Threaded Implants with and without Platform Switch: A 3-D Finite Element Analysis

Objectives: This study examined the effects of stress distribution at three abutment–implant interfaces on various implant systems. Materials and Methods: Group I: tri-channel internal connection (Nobel Biocare), Group II: 1.5-mm deep internal hex (BioHorizons Co. Birmingham, USA), and Group III: ADIN Touareg, to create computerized models of implants and mandibular modeling software, close fit WP, ANSYS Version 14.0 for finite element analysis (FEA), Hypermesh 12 for meshing and CATIA were used. A top-notch scanner was used to scan the implant. CATIA software created computerized models using all the aforementioned data. By applying bonded state on the abutment–implant borders and four various load conditions within the implant system, finite element method modeling was carried out. The computerized model was imported into the ANSYS program. To compare the groups, a statistical analysis was conducted. Result: Through the use of three-dimensional FEA, the samples were assessed. Stress was found to be utmost in Group I, followed by Group III and Group II, at 80 N, 80 N with a 15° tilt, 250 N, and 250 N with a 15° tilt, and the divergence was statistically inconsequential. Conclusion: The tri-channel internal connection displayed the highest stresses compared to the internal hex within the constraints of the current study.
