Abstract:

This new system includes a dental implant that has a cylindrical shape for most of its length, ending in a tapered apical portion. The cylindrical portion of the dental implant is divided in two areas, one that is rougher and threaded, and one that is smoother and not threaded. The non-threaded cylindrical portion at the coronal end of the dental implant is much more extended than in other dental implant systems, to ensure placement of threads under the bone level even when placed in bone that has irregular anatomy or a narrow crest. The non-threaded portion has a minimally modified surface that is compatible with placement under or above bone level, or under or above gingival level. The cylindrical shape of this portion ensures that the margin of the crown can always be extended to the gingival margin, and not only to a fixed “shoulder” area.
