FIELD OF THE INVENTION

This invention relates to the field of dental implants, mounts, abutments and drivers

BACKGROUND OF THE INVENTION

Dental prosthetic support implants are used to support prosthetic teeth on a patient's jaw bone. They are generally delivered in a sterile condition within a storage vial. To reduce risk of infection, the implants must be removed from the vial and installed in a manner that prevents contamination. Each implant generally includes a threaded shaft that is threaded into a pilot hole (osteotomy site) formed in a jaw bone through an opening formed by cutting and laying back a surgical flap of the gum tissue covering the bone. Once the implant has been installed, either at the time of implantation of at a later time, the gum tissue is closed around the implant with a stem of the implant protruding upward through the gum tissue. Once the gum tissue has healed around the implant, a prosthetic tooth is formed around or mounted on the protruding implant stem. Most implants include hexagonal prosthetic interface sockets formed axially downward into the respective top ends of their stems. The hexagonal configuration of such a socket serves to prevent relative rotation of a prosthetic tooth that has been formed onto the stem and into the socket. The orientation of hexagonal socket of the installed implant, determines the orientation of the abutment which would be positioned on the said implant. During the installation of the implant, its orientation (and orientation of hexagonal socket respectively) is of paramount importance and its decides, inter alia, the orientation of the abutment. SUMMARY OF THE INVENTION

The present invention comprise a kit of dental devices and a method for positioning of an implant inside the bone, and at the same time providing the desired orientation of the said implant.

The dental implant comes generally in a sterile package containing the implant itself and disposable mount which is used to provide a connection to an insertion tool (such as hex driver) used to place the implant into the bone.

In single stage implants the implant package also includes an abutment which is attached to the implant before its installation into the bone.

During the implant installation it is important to know the orientation of hexagonal socket of the said implant. This is achieved by providing a kit comprising a driver tool, an implant mount and a single stage abutment with facet indicators positioned on their body, said indicator may be implemented in form of one or more notches or grooves, each notch is corresponding to one facet of hexagonal socket of said implant.

FIG. 1 shows an exemplary embodiment of single stage implantation navigation abutment 1. Abutment 1 usually comes in sterile package with dental implant and mount. Said abutment 1 comprise a cylindrical body 1 1 having a preferable length of 8.5 mm. Abutment 1 also comprise a polygonal or as shown in this embodiment a hexagonal protrusion 12, said hexagonal protrusion 12 positioned at the apical end of said abutment 1 . Said hexagonal protrusion 12 has a width preferably of 2.5 mm and length preferably of 2.5mm. At the coronal end of said abutment there is polygonal or as in this case a hexagonal socket 13. This socket 13 has a width preferably of 2.5 mm and length preferably of 6 mm. The abutment 1 also comprise a circular rim 15 located near the apical end of said abutment 1 , just above hexagonal protrusion 12. Said circular rim 15 has a preferable diameter of 4.5 mm and used as a support for prosthesis. The body 1 1 of said abutment 1 also comprise at least one (or more preferably six) facet indicator, in form of grooves 14, positioned on outer surface of said body 1 1 , wherein each indicator corresponds to one facet of hexagonal protrusion 12 and hexagonal socket 13.

During the implantation process, the abutment 1 is inserted into implant and secured to it by a screw. After this the implant together with an abutment are screwed into the bone with help of a mount and a driver, till the desired orientation of hexagonal socket is reached, this orientation is known to physician from orientation of grooves 14 of the abutment 1 . The desired orientation of said implant allows achieving an alignment between neighboring abutments and also making possible the use of standard abutments with this implant.

Said abutment 1 has a preferable length of 10.4 mm and is made of biocompatible material, such as titanium or titanium alloy, for example Ti-6A1-4V. FIG. 2 shows an exemplary embodiment of disposable dental mount 2. Said mount 2 comprise head part 25 in form of hexagon of width of 6.35 mm and height of 6 mm. The head part 25 comprise a hexagonal socket (not shown) which may be engaged with suitable driver tool or with a ratchet tool. The mount 2 also comprise a body 21 having a length of 18.5 mm, said body 21 has an upper part 26 which is used to hold said mount 2 together with implant in sterile package. The mount 2 also comprise a hexagonal (or polygonal) protrusion 23 positioned on the bottom end of said body 21 and cylindrical retainer 24 positioned on the bottom end of said hexagonal protrusion 23 and having a diameter of 1.2 mm and length of 4 mm, said cylindrical retainer 24 has a form of a clip and is used for retention of implant by said mount 2. The body 21 comprise at least one (or more preferably six) facet indicator, in form of grooves or notches 22, positioned on outer surface of said body 21 , wherein each indicator corresponds to one facet of hexagonal protrusion 23 and hexagonal socket. During the implantation process, the mount 2 is inserted into implant and is hold by retention of a clip. After this the implant together with the mount are screwed into the bone with help of a mount and a suitable tool (ratchet), till the desired orientation of hexagonal socket is reached, this orientation is known to physician from orientation of grooves or notches 22 on the body 21 of the mount 2. The desired orientation of said implant allows achieving an alignment between neighboring abutments and also making possible the use of standard abutments with this implant.

FIG. 3 shows an exemplary embodiment of hexagonal driver 3. Said driver 3 comprise rectangular head 34 of width of 4 mm and height of 6 mm and hexagonal head 35 having width of 6.35 mm and height of 6 mm . The head part 34 or 35 may be engaged with suitable tool, such as ratchet tool. The driver 3 also comprise a body 31 having a length of 18.5 mm or shorter. The d/iver 3 also comprise a hexagonal (or polygonal) protrusion 33 positioned on the bottom end of said body. The body 31 comprise at least one (or more preferably six) facet indicator, in form of grooves or notches 32, positioned on outer surface of said body 31 , wherein each indicator corresponds to one facet of hexagonal protrusion 23 and hexagonal head 35.

Driver 3 is inserted into implant, or into an abutment, or into a mount and is used for screwing an implant into the bone with help of a suitable tool (for example, ratchet), till the desired orientation of hexagonal socket of the implant is reached, this orientation is known to physician from orientation of grooves or notches 32 on the body 31 of the driver 3. The desired orientation of said implant allows achieving an alignment between neighboring abutments and also making possible the use of standard abutments with this implant.

The above embodiments are given as illustrative examples and are not intended to impose any limitations on the invention. It will be readily appreciated that many deviations may be made from the specific embodiments disclosed in this specification without departing from the invention. Accordingly it is intended to cover all such modifications as within the scope of this invention.
