Finite Element Analysis of Stress Distribution in 30% CFR PEEK Implant with Varying Thread Designs.

The surgical effectiveness of dental implants is entirely reliant on the biomechanical behaviour of the implant material, the pitch of the implant, and the kind of implant thread design. An enhancement in the implant's efficacy may be achieved by the selection of the appropriate settings. This research aimed to examine the stress distribution in cortical and cancelous bone by using various kinds of implant thread designs with a pitch value of 0.8mm and a 30% carbon fiber reinforced plastic (30% CFR-PEEK). 30% CFR-PEEK, which stands for carbon fiber reinforced (30%) poly ether ether ketone, has shown its efficacy as a viable alternative to titanium in orthopaedic applications. This research investigated four implants with distinct thread designs, namely V-thread, square thread, buttress and reverse buttress. The mandibular molar area, consisting of both cortical and cancellous bone, is often regarded as isotropic and homogenous. The implant was created using SolidWorks software, and a vertical force of 200 N was exerted. The stress values were determined by the use of the Finite Element Analysis (FEA) technique using ANSYS software. When the bone implant interface was taken into consideration, the von Mises stresses were found to be at their lowest at the cancellous bone for the V thread design, whereas the square thread design showed the highest stresses at the cancellous bone under 200N axial load. When cortical bone was taken into consideration, the square thread design seemed to have the lowest von Mises stresses, whereas the V thread design had the highest stress value. Therefore, the findings that were obtained may be employed therapeutically for the purpose of making a suitable selection of implant thread design in order to achieve a predicted level of success with implant treatment, within the constraints of this research.
