A dental implant with a post element is inserted into a jawbone with a mounting element attached to the post element, with the post element designed as a ceramic body of yttrium- and/or aluminum oxide stabilized zirconium oxide. The dental implant has improved ingrowth during osseous implant healing. The surface of the dental implant is provided with at least one partial area that has nanoscopic pores or an otherwise executed nanoscopic structure that has a depletion zone with a reduced yttrium- and/or aluminum oxide element.
