Abstract :

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±0.33and 315.43±0.59). Also, deflection takes 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. Recent Publications 1.
