Ceramic dental implant

A ceramic dental implant for implantation into a jaw bone, the implant extending from an apical end to a coronal end, the implant having

• a blind bore, which is open towards the coronal end of the implant and extends towards the apical end along a central longitudinal axis, the blind bore comprising
• a threaded section having a base surface from which a thread protrudes radially inwards, the base surface defining the maximum radius of the thread as measured from the central longitudinal axis, the thread having a coronal flank and an apical flank connected by a crest at their radially inner ends, the crest defining the minimum radius of the thread as measured from the central longitudinal axis, the thread extending in a helical manner along the axial length of the threaded section and having a thread depth defined by the difference in radius between the base surface and the crest, the threaded section comprising
• a main portion, within which the maximum radius of the thread remains constant along the length of the main portion, and
• apically adjacent to the main portion, a tapered portion within which the base surface tapers radially inwards in the apical direction from the maximum radius of the thread in the main portion to the minimum radius of the thread at the apical end of the tapered portion, the tapered portion extending over an axial length greater than a thread pitch, so as to form a tapered thread having a gradual reduction in the thread depth, the tapered thread extending over more than one thread turn.
