The major diameter is uniform (3.0, 3.4, 4.0 and 5.0 mm), the thread depth is variable from 0.3 – 0.*3 mm.

The helix angle is *0 degrees and the crest width varies from *0 ***0 um.

The design provides:
1. A sharp “V” shape thread on the apical area that, with the aid of the apical tap provides a cutting surface which the implant can be placed in bone as an “self tap”.

2. The Acme thread on the coronal area which toward the coronal area the crestal length increases (max. **0 um). This type of translation thread does not have the disadvantages of the square threads (e.g. difficult to cut, cannot be adjusted to compensate for wear) and have the advantages of being somewhat stronger.
