Implant Classic in its upper part has a microthread for a cortical layer. The implant’s body is root-shaped. Due to the thread pitch of 0.6 mm an implant is cylinder-shaped. This implant is mainly used in the first type of bone, but it may be used in all types of bone as well. Due to the triangular shape of the thread in the apical part the implant has qualities of self-tapping.
