Biomechanical behavior of different implant abutment materials

Purpose: to check the mechanical properties and Finite element Stress Analysis of 3 implant abutment materials. Materials and methods : Fifteen bars (25mm length, 4mm. thick and 5mm.width) of 3 abutment materials ; High Performance polymer Hybrid abutments , Nano-Fiber reinforced Composite and Fiber strengthened Composite divided into 3 teams were exposed to Flexure Strength and Deflection tests. Fifteen implant abutments (two components abutment) coated by all ceramic crowns divided into 3 teams were exposed to Static Fracture Resistance take a look at and Finite element Stress Analysis . Results: Flexure Strength tests mean and standard deviation of bar specimens showed vital distinction, wherever gp I, II, III were 519.29±0.46, 200.74±0.33 and 315.43±0.59. Also, Deflection take a look at mean and standard deviation were three. 052±0.040, 0.984±0.106, 2.028±0.027 receptively discovered vital distinction. The comparison between fracture resistance mean and standard deviation of the tested abutment 3 groups were 642.00±.5.637, 306.00±30.496 and 514.40±12.915 respectively and discovered significant distinction. Finite part Stress Analysis of applied vertical load on the 3 abutment materials failed to have clear distinction however the smallest amount stresses created on bone with Nano-FRC abutment(16.2) followed with FRC (17.32) then BioHPP abutment (18.55). Conclusion: Fracture strength of BioHPP abutments with ceramic crowns had the potential to resist most occlusal forces, conjointly showed higher fracture patterns than the FRC and NFRC abutments, and showed a higher stress distribution on the set, suggesting a decent mechanical behavior.
