FEM: Mono-implant cement-retained crown with two-different adhesive materials

Background: The finite element method (FEM) is expected to be one of the most effective computational tools for measuring stress on implant-supported restorations. This study was designed using 3D-FEM evaluate effect two adhesive luting types cement occlusal and deformation a hybrid crown cemented mono-implant. Materials Method: mono-screw STL file imported into CAD/CAM system library from database supported by De-Tech Implant Technology. assist in accurate reproduction details design simulated implant abutment. Virtually, digital an abutment screw. A minimum thickness 1mm marginal fitting 1.2mm intended. An 80µm interface this study’s purposes applied U-Cem Premium 3M RelyXTm adhesives. FEA software meshed tetrahedral elements. Two three-dimensional models were under different loads 200N, 400N, 600N, 800N, 1000N, 1200N, 1400N. Results: results showed that ceramic attached mono-implant with each exhibited comparable strain. However, amount distortion less when RelyX used. Conclusion: Overall, it advisable use up 1400N load.
