PEEK: Finite Elements Model of PEEK-IMPLANTS Crestal and Basal To check if stress distribution shall be better than with rigid implants and response in bone will be adequate 18. PEEK: Finite Elements Model of bone and implants Cortical bone, Spongeous bone, Cortical bone Constraint under 30; variation between 10 to 80 MPa 20 MPa: deplacement/ deformation of bone: 4 micron Meningaud, Jean-Paul, Donsimoni, Laprs titane, le PEEK ?

PEEK: Mechanical constraints in FEM 20 Mpa (162 N): deplacement/deformation of bone: 5 micron 60 Mpa (389 N): deplacement/deformation of bone: 5 micron 20. PEEK: Mechanical constraints in FEM Unilateral 20 MPa Unilateral 30 MPa Unilateral 40 MPa Unilateral 60 MPa 21. PEEK: FINITE ELEMENT STUDY OF PERSO-B Figure 8: Constraints obtained on the dental implant 7. Maximum constraints: 245 MPa Conclusion: The maximum constraint being lower than the yield stress of the PEEK (337 MPa), one can deduce that the implant resists the efforts which are applied to it. Figure 3: Constraints obtained on the dental implant 9. Maximum constraints: 305 MPa Conclusion: The maximum constraint being lower than the yield stress of the PEEK (337 MPa), one can deduce that the implant resists the efforts which are applied to it. 22.
