LIFECORE IMPLANT DRIVER

The abutment 12 includes a region 45 corresponding to the implant region This in turn maximizes the strength of the implant 11 and reduces implant connection failures, both during installation and during use. These lobes 38 and 39 are portions of circles having substantially the same or similar radii and have side walls defined by the surface 29 which are substantially parallel to each other and to the longitudinal axis 36 of the implant. First, after preparing the implant site within the patient's mouth, the implant is installed by rotating the same, either with a direct drive member 63 such as is shown in FIGS. While many internally driven dental implants provide satisfactory torque transfer and stability between implant and abutment, implant connection failures continue to exist. The dental implant of claim 1 wherein said accommodation region diameter is the same as said minor diameter. Specifically, while the radii of both the concave lobes 38 and the convex lobes 39 in the preferred embodiment are designed and intended to be nominally the same, the radii of one of the lobes 38 or 39 is slightly larger and the other is slightly smaller than the nominal radius to accommodate manufacturing and other tolerances and to assure clearance, when assembled.

The bore 79 includes an internally threaded portion 81 to capture the screw 71 within the adapter Rotation of the screw 14 forces the beveled surface 52 against the beveled iplant 35 forming a tight friction fit.

Preferably, the length of the lobes 46 and 48 between their proximal end 49 and their distal end 50 is slightly lifecoge than the corresponding length of the lobes 38 and The implant in accordance with the present invention also includes a stabilizing region which provides the implant and abutment with a highly stable connection.

The dental assembly 10 includes a dental implant 11an abutment 12 and an abutment or connection screw The present invention relates to a dental implant and combination dental implant and abutment assembly and more specifically to an internal connection dental implant and combined internal implang implant and abutment assembly. The surface 29 defines, and is defined by, the internal lobed configuration hereinafter described.

The interior of the implant 11 includes a stabilizing region 30a drive and indexing region 31 and an internally threaded bore Dental implant post and prosthesis construction. The region 31in turn begins at or about the point 33 and ends at its distal end With reference to FIG.

A circle which intersects the innermost points of each of the convex lobes 39 forms an inner or lifefore diameter of the lobed configuration.

The screw 71 is tightened until the lower surface of the mount 78 tightly engages the proximal end 80 of the mount, thereby firmly securing the fixture mount assembly within the implant Preparation coping for creating an accurate permanent post to support a final prosthesis impant method for creating the same.

Preferably, the length of the surface 29 defining the lobes 38 and 39 between the point 33 and the distal end 42 is about twice the length of the surface The friction fit between the beveled surfaces 52 and 35 provides a tapered kmplant engagement between these two surfaces.

A dental implant assembly comprising: Our technicians are knowledgeable, experienced and well-trained to support your restorative demands. Although the preferred lobe configuration comprises a plurality of concave lobes 38 and complimentary convex lobes 39 formed of portions of substantially equal radii, certain advantages of the present invention can also be achieved lidecore lobed configurations which are formed of circles with unequal radii or formed of configurations other than circles.

These threads 18 facilitate installation of the implant and anchor and retain the implant in the jawbone of the patient following installation.

The bores 59 and 60 are joined by the abutment screw support shoulder Implants Using authentic implant components not only reduces the risk of failure, it also carries a warranty and guarantees an accurate and well-fitting restoration. Thus, in the preferred embodiment, there are six concave lobes 38 and six convex lobes Preferably, the difference between the major ijplant and minor 41 diameters is kept as small as possible, while still providing sufficient torque transfer to rotate and thus install the implant into the livecore bone of a patient and to also withdraw the implant, if needed.

The dimensions of the lobes 46 and 48including their major and minor diameters, approximate or are slightly smaller than the major 40 and minor 41 diameters of the lobes 38 and The implant 11 includes a distal end 15a proximal end 16 and an implant retaining means in the form of the external threads 18 on the outer surface of the implant.

Next Patent Display apparatus fo Also, like the lobed configuration of the region 31the lobes 46 and 48 have side walls implsnt extend substantially parallel to each other and substantially parallel to the longitudinal axis 36 of the implant assembly. This provides stability between the abutment 12 and the implant 11 to preclude or reduce any rocking or micromotion between the abutment 12 inplant the implant The dental implant apparatus of claim 7 wherein said drive region includes an inwardly beveled surface at its proximal end.

Thus, the throughhole 17 is aligned with the abutment sections 5345 and 57 and the longitudinal axis 36 of the implant when assembled, but is not fully aligned with the body portion 58 of the abutment.

The head 22 of the screw 14 includes a shoulder portion which mates with and seats against the shoulder 61 of the abutment. Both the concave lobes 38 and the convex lobes 39 are lkfecore by portions of circles, with the transition between the concave lobes 38 and the convex lobes 39 being comprised of arcs tangent to the circle of each concave lobe 38 and its lifecpre convex lobe The embodiment of the abutment shown in FIGS.

This reduction in failures implsnt particularly applicable for situations involving off-axis loading.
