Implant root for tooth implanting

摘要

An improved implant root for tooth implanting into the alveolar bone of a patient, said implant root comprises: a coarse threaded portion of the implant root is formed to have a wider base and to have an extension root with various radiant thread constructed, characterized with a circumferential constricted neck between these two segments. Both segments are designed to be seated into alveolar bone as implant root fixture. The widest diameter of the upper and lower segment is either equal or the lower base is slightly wider than lower segment for the most of it. The constricted neck in between the base and extension of the segments and the shape of the lower base segment allow the lower base implant root to serve as a primary stability anchor. Combining the concept of wider base with extensions allow the base segment of the implant fixture becomes a physiological anchor healed in bone and to increase the stability of the implant around the implant fixture after bone heal thus advantage the implant to be placed in some type of bones needing this kind of anchorage.
