Abstract
A method of designing a skeletal implant comprises measuring physical characteristics of the bone to be implanted, generating a macro-design of the implant based on the physical characteristics, and determining a micro-design for the implant to ensure that strain in the bone is kept between 100 and 3000 microstrain to promote bone growth and to minimize bone resorption during functional loading. In an alternate embodiment, a dental implant comprises a crest portion having a circular bottom surface, an opposite circular top surface, and a side wall intermediate the bottom surface and the top surface, the top surface being adapted for attaching the dental prosthesis thereto. A circular base portion has a crestal end, an opposite apical end, and a core section intermediate the crestal end and the apical end having an outer surface. A helical thread extends about a portion of the outer surface of the core section that secures the device within existing bone. The bone contacting surface area of the thread increases as the thread nears the crestal end, thereby increasing the surface area over which force is distributed from the implant to the surrounding bone so as to minimize resorption of the existing bone and promote growth of new bone tissue adjacent the device. In an alternative embodiment, a dental implant having a crest module, a threaded first section and a second section, comprises a surface disposed on a selected one of the crest module or the second section for distributing to the bone in a non-longitudinal direction a portion of any longitudinally directed force on the implant.
