New Subperiosteal Dental Implant Design with Finite Element Analysis and Mechanical Validation: A Design Validation Study.

New subperiosteal dental implants were designed to offer new options to edentulous patients with severe bone resorption for whom endosseous dental implants are not advisable. In our study, we aimed to design and manufacture subperiosteal dental implants with a minimum volume to facilitate surgical maneuvers and metal coverage by mucosa while ensuring maximal long-term implant strength and functionality. With cone-beam CT-scan data obtained from an edentulous patient, a maxilla and mandible recreation were created, and subperiosteal implants were designed and analyzed with FEA (250 MPa infinite-life limit stress).
