The aim of this study was to compare two different types surgical approaches, intrasinus and extramaxillary, for the placement zygomatic implants treat atrophic maxillae.A computational finite element simulation used analyze strength implant anchorage both approaches in various occlusal loading locations.Three-dimensional models craniofacial structures surrounding a region interest, soft tissue framework were developed using computed tomography image datasets.The modelled computer-aided design software.The bone assumed be linear isotropic with stiffness 13.4 GPa, made titanium 110 GPa.Masseter forces 300 N applied at arch, loads 150 vertically onto surface locations.The approach demonstrated more satisfactory results could viable treatment option.The extramaxillary also recommended as reasonable option, provided some improvements are address cantilever effects seen that approach.
