Dental implant thread

A dental implant comprising

• a threaded portion extending along a central longitudinal axis from an apical end to a coronal end,
• the threaded portion comprising a core from which threading extends radially outwards,
• the threading comprising an apical flank, a coronal flank and a lateral surface connecting the apical and coronal flanks, the lateral surface defining the radially outermost surface of the threading, the threading extending along a length of the threaded portion in a helical manner and a thread width narrowing in the radially outwards direction such that the threading is widest where it contacts the core and narrows towards the lateral surface,
• a core diameter of the threaded portion being defined by an outer diameter of the core and an outer diameter of the threaded portion being defined by the lateral surface of the threading,
• wherein:
• over at least a section of an axial extent of the threaded portion, a thread profile of the apical and coronal flanks of the threading is formed of exactly three sub-segments arranged sequentially in the radial direction, the sub-segments comprising a middle sub-segment, a radially innermost sub-segment, and a radially outermost sub-segment,
• in each sub-segment, the apical and coronal flanks taper towards one another at a constant angle, the middle sub-segment having a taper angle that is greater than the taper angles of the radially innermost and radially outermost sub-segments, the taper angle formed between the apical and coronal flanks in the radially outermost sub-segment being less than 30°, and
• the thread width at the core is constant along a full axial extent of the threaded portion, the thread width being a linear distance measured between the coronal flank and the apical flank, the thread depth along said threaded portion changes, resulting in changes in a width of the lateral surface, and the thread depth is a dimension of the threading extending from the core to the lateral surface and is transverse to the width of the lateral surface.
