Dental implantation is currently one of the major surgeries in dental reconstruction to restore patients' normal masticatory function. Although dental implantation procedures have a high success rate, many reports indicate that the occurrence of post-surgical bone resorption at the implant site may increase the chances of dental implant failure or fracture; among which, damage in the mandibular molar area is the most severe. Many of the recent studies analyze the success of dental implants by assessing the osseointegration of the oral cavity. To date, there are no relevant studies that use bone resorption as a major element in research. The present study attempts to estimate the impact of bone resorption on the implant itself at a later stage of the implant procedure under various surgical conditions using the Taguchi method and finite element analysis (FEA). The result showed a positive correlation between the magnitude of the stress and the length of the implant, while the diameter of the implant is negatively correlated. The difference in the thickness of the cortical bone does not cause significant impact to the stress of the implant, and the diameter of the implant is the most significant factor affecting stress. Recommendation is made to use implants with a larger diameter for better surgical outcomes.
