- a connecting portion having on its outer surface a fine threaded portion connected with an abutment of a crown;
a coarse threaded portion on a lower area below said connecting portion, surfaces of said coarse threaded portion have sharp threads;
at least two helical treated surfaces formed on said coarse threaded portion and extending in a vertical direction from a bottom end to a top end of said coarse threaded portion and extending in whole length of said coarse threaded portion, said treated surfaces are treated with roughened coatings.

Abstract
An improved implant root for tooth implanting, a coarse threaded portion of the implant root is formed to have at least two helical treated surfaces extending from the bottom to the top of the implant root of the coarse threaded portion each being treated with a roughened coating (for example, covered with a hydroxyapatite coating) and extending in the whole length of the coarse threaded portion and each extending in the vertical direction. The areas of the roughened coatings can thus be increased in favor of fast growth of a bone of a denture base after implanting into the bone to envelop the implant root; this can shorten the curing process from implanting the implant root to mounting a crown.
