  • Patent number: 8821159
    Abstract: A dental implant guiding device is applied in guiding the drill of the drilling apparatus in different dimensions. The device includes a guiding module and a guiding seat. The guiding module contains at least one guiding unit where a sleeve with a cavity is disposed. A guiding hole and a guiding slot, where an opening at a fringe of the guiding unit is defined, are disposed at two sides of the sleeve. The guiding seat forms a first hole. At two sides of the first hole, a first guiding shank and a second guiding shank respectively corresponding to the guiding hole and the guiding slot are disposed. The second guiding shank slides into the guiding slot, which allows the first guiding shank inserting into the guiding hole for the drill to position at the center of the cavity of the sleeve, thereby achieving the fast positioning and friction reduction.
