A 3-D Finite Element Analysis of Stress Distribution on Implant-supported Fixed Prosthesis with Four Different Commercially Available Implant Systems
AIM: To investigate by the finite element analysis comparison of stress distribution on the cortical and cancellous bone in an implant-supported yttrium tetragonal zirconia polycrystals (Y-TZP FPD) in four different widely used implant systems under different loading conditions.
MATERIALS AND METHODS: Four 3-D finite element analysis (FEA) models of mandible having different implant systems with dimensions 8.0 mm × 5 mm in the second premolar and molar region were developed. In these models, abutment was tightened and 3-unit implant-supported Y-TZP FPD were cemented. A lateral force component of 100 N at 30° to the occlusal plane and a vertical intrusive force component of 250 N were applied to the central fossa of the FDP and the stress on bone around the implant was analyzed by FEA.
RESULTS: In the four implant systems, the maximum stress values on the crestal bone differ for the different implant systems for the two loading conditions applied. In both cases, the maximum stress values on the cortical bone were in ADIN Touareg Closefit WP implants and the maximum stress on the cancellous bone was observed in the Nobel Speedy Groovy implants.
CONCLUSION: The ADIN Touareg Closefit WP implant system induced maximum stress on the crestal bone in both axial and buccolingual loading. Nobel Speedy Groovy implant system favored more equitable load distribution to the peri-implant crestal bone when compared to the other three implant systems.
CLINICAL SIGNIFICANCE: From this study, it was found that out of all the implants used for the study, the Nobel Speedy Groovy implant system favored more equitable load distribution due to the platform switch design contrary to the other systems and at the cancellous bone the least load was transferred by the Nobel Active implants due to the reverse buttress thread design and larger thread pitch.
