Abstract
A ceramic dental implant for implantation into a jaw bone extending from an apical end to a coronal end. The implant has a blind bore open towards the coronal end and extends towards the apical end along a central longitudinal axis. The blind bore includes a threaded section having a base surface where a thread protrudes radially inwards. The threaded section includes a main portion, wherein the maximum thread radius remains constant along the portion length and, adjacent to the main portion, a tapered portion where the base surface tapers radially inwards from the maximum thread radius to the minimum thread radius at the apical end of the tapered portion, the tapered portion extending over an axial length greater than the thread pitch, forming a tapered thread having gradual reduction in thread depth, the tapered thread extending over more than one thread turn.
