An eposteal implant is a device that receives its primary bone support by means of resting upon the bone itself. Though most practitioners prefer endosteal implants, in which the implant is placed in the bone, the eposteal implant may still be used in cases of extreme bone resorption or high risk of bone resorption. Since substantial bone is required in order to place an endosteal implant, some patients may require a bone grafting procedure prior to receiving the implant. However, some patients are at higher risk for bone resorption due to other underlying factors and are not good candidates for grafting and endosteal implants. Though the eposteal implant method is mostly considered outdated, it does still have applications for patients in this resorption risk category. To secure an eposteal implant, it is attached to the jawbone rather than being drilled and placed inside the bone to act as a root replacement.
