Introduction: The purpose of this investigation was to evaluate the bone microstrain in bruxomanist patient with dental implants through the finite element analysis (FEA).
Methods: It was modeled one (1) Tapered Screw-Vent® implant (ref. TSVB10 Zimmer Dental) with a length of 13 mm x 3.7 mm of diameter, with a platform of 3.5mm, a zirconium abutment, a screw, lutting agent, a monolithic ceramic crown of a central superior incisive, cortical and cancellous bone, using the CAD Software of Solid Works 2010 (SolidWorks Corp., Concord, MA, USA), and then it was processed and analyzed through the ANSYS Software 14th edition. Those were evaluated von Misses stress and μstrain, applying loads in transversal direction with magnitudes of 200N and 800N.
Results: Every one of the elements of the modeled structure (Crown, Abutment, Screw, Implant, Cortical and cancellous bone) submitted to the incremental loads, presented Von Misses and μstrain particular values with a lineal behavior. Submitting the modeled structure to loads of 200N and 800N, no one of the components suffered permanent deformations, it means, it was not exceeded the yield strength. Conclusion: According to the mechanic behavior of the modeled structure, in bruxomanist patients is suitable the use of a dental implant in a superior central incisive, because the parafunctional loads generated by the bruxism are not superior to the presented in the modeled structure, therefore those not generate permanent deformations or damage in the bone.
