Parts have complex geometries are easily produced by additive manufacturing method. This practicality in production carries dental implant designs to a very advanced level. The possibilities of the digital age with additive manufacturing bring different perspectives to the search for economical solutions in dental implant design and production. Geometries which have significant potentials to be able to apply to the designs allows researchers to make optimum improvements. Solid dental implants produced from biocompatible materials are placed in the jawbone to support dental prostheses. The alveolar bone located on the jawbone is a living tissue that can continuously regulate itself in response to external physiological and mechanical loads, surrounds the tooth root and fixes it in place. Resorption (resorption) can occur in the alveolar bone due to hereditary factors, insufficient oral care, inflammation and external variable load factors. Resorbed jawbone can cause orthopedic problems such as implant loosening. In this study, a new implant design has been studied in order to minimize bone resorptions caused by mechanical load and complications from the implant. Literature studies support the porous structures to be efficient for bone growth and regeneration in vivo conditions. The porous structure is used to ensure the living bone tissue to be able to grow spirally into the implant in implant design. This porous structure has been optimized with the lattice structure oriented topological approach and the mechanical strength of the implant has been controlled. Problems such as boundary conditions of complex geometries, loadings and material behavior are solved by the finite element method.
