A dental implant 1 includes a coronal portion 2 and a body portion 4 that are continuous with each other. The coronal portion 2 defines the proximal end 1p of the bone implant and the body portion 4 defines the distal end 1d of the implant 1. The body portion 4 comprises an inner core 4i that is fitted with at least one threading 6 extending horizontally along a horizontal plane 30a and progresses along the length of the core of the implant body 4. The inner core 4 defines an inner diameter 4i of the body portion 4 while the thread 6 defines the outer diameter 4e of the body portion 4 .
[0121] The shape and/or profile of the body portion 4 can be highly variable and can take on a plurality of shapes and/or configurations and/or profiles, for example, including, but not limited to, straight, tapered, tapered , cylindrical, linear, parallel, symmetric, asymmetric, trapezoidal, mixed conical, segmented, multi-segmented and any combination thereof.
[0122] The implant 1 may additionally comprise microthreads 8 along the coronal portion 2 and/or body portion 4. Optionally, the body portion 4 may comprise both microthreads 8 and thread 6.
[0123] Figure 1B shows a schematic block diagram representation of a dental implant thread 6 that specifically shows the aspects of the dental implant thread. Figure 1B shows different thread profiles 6 which are known in the art to have different characteristics. Thread 6 extends from the central portion of the implant body 4 along a horizontal plane 30a represented by the dashed line.

As can be seen, the subsegments 121 can be configured to be cylindrical and/or trapezoidal and/or circular cylindrical in any arrangement, however, the total core diameter 120c is apical and sequentially decreasing.
