Abstract
A restorable zirconium dioxide-based one piece implant includes an implant root made of zirconium dioxide and having a bottom coarse thread portion mounted in a gum of a patient and a top fine thread portion at a top side of the bottom coarse thread portion, an abutment formed integral with a top end of the top fine thread portion of the implant root for mounting a crown, and a vertical center hole extending vertically downwardly from a topmost edge of the abutment into the implant root toward a bottom end of the bottom coarse thread portion of the implant root and having a length greater than ⅔ of the combined length of the implant root and the abutment, so when the abutment breaks, the vertical center hole provides a space for the application of post and core technology to embed a post in the broken abutment to restore the abutment.
