A dental implant having an outer surface renewable while the dental implant remains in place, the dental implant comprising: an implant body comprising: an anchoring base including a screw thread for anchoring in a dental socket of a jawbone, and a shaft extending proximally from the anchoring base comprising an abutment attachment region; and the thin-walled removable sleeve element extending along the shaft; wherein: the removable sleeve element comprises a receiving bore, configured to match the circumference of the proximal end, such that the removable sleeve element is configured to be removed from the circumference of the shaft, thereby exposing a surface underneath to become a new outer surface, and a ratio of thicknesses of the wall of the removable element and of the proximal end of the implant body is about 1:10 or a smaller ratio, such that the implant body maintains an approximately functionally equivalent implant shape to the complete dental implant upon removal of the removable sleeve element, including sufficient width for osseointegration and strength sufficient for functional support of a prosthetic device including acting as an anchoring base for an abutment attached to the abutment attachment region, wherein the removable sleeve element extends distally from the abutment attachment region. an implant body comprising: an anchoring base including a screw thread for anchoring in a dental socket of a jawbone, and a shaft extending proximally from the anchoring base comprising an abutment attachment region; and an anchoring base including a screw thread for anchoring in a dental socket of a jawbone, and a shaft extending proximally from the anchoring base comprising an abutment attachment region; and the thin-walled removable sleeve element extending along the shaft; wherein: the removable sleeve element comprises a receiving bore, configured to match the circumference of the proximal end, such that the removable sleeve element is configured to be removed from the circumference of the shaft, thereby exposing a surface underneath to become a new outer surface, and a ratio of thicknesses of the wall of the removable element and of the proximal end of the implant body is about 1:10 or a smaller ratio, such that the implant body maintains an approximately functionally equivalent implant shape to the complete dental implant upon removal of the removable sleeve element, including sufficient width for osseointegration and strength sufficient for functional support of a prosthetic device including acting as an anchoring base for an abutment attached to the abutment attachment region, wherein the removable sleeve element comprises a receiving bore, configured to match the circumference of the proximal end, such that the removable sleeve element is configured to be removed from the circumference of the shaft, thereby exposing a surface underneath to become a new outer surface, and a ratio of thicknesses of the wall of the removable element and of the proximal end of the implant body is about 1:10 or a smaller ratio, such that the implant body maintains an approximately functionally equivalent implant shape to the complete dental implant upon removal of the removable sleeve element, including sufficient width for osseointegration and strength sufficient for functional support of a prosthetic device including acting as an anchoring base for an abutment attached to the abutment attachment region, wherein the removable sleeve element extends distally from the abutment attachment region.
