  • the invention also relates to the combination of a dental implant and a device and method for carrying and driving such implant and a combination of an dental implant abutment screw and a device and method for carrying and driving such screw.
  • dental implants commonly include a body with external threads or other means for mounting and retaining the implant within the patient's mouth. Installation of the implant commonly involves rotation of the implant into a predrilled or tapped site using a drive member such as a ratchet or other rotation means.
  • the implant also includes a drive region which may be located externally or internally at or near the proximal end of the implant.
  • Various structures for both externally and internally driving the implant currently exist.
  • Certain types of dental implants also include abutment screws for connecting an abutment or the like to the implant.
  • Various means also currently exist for accomplishing this installation.
  • the present invention relates to a combination carry and drive device for carrying a threaded member to an installation site and for driving or rotating such threaded member into that site.
  • the invention has particular applicability to the field of dental implants as a device for carrying an implant to an installation site and rotationally driving such implant into the installation site and/or carrying a dental implant component such as an abutment screw to an installation site and rotationally driving the screw into the implant to connect the abutment.
  • the combination carry and drive device of the preferred embodiment of the present invention is designed for use with a rotation member such as a dental implant or an abutment screw which is provided with an internal driving recess having one or more driving surfaces or lobes.
  • the carry and drive device includes a driver end which is designed for insertion into the driving recess and which has an exterior configuration substantially matching the driving configuration of the driving recess.
  • the driver end also includes an interference or engagement surface designed for carrying engagement with a portion of the driving recess.

  • the driver end of the device is inserted into the driving recess of the implant. After limited insertion, a portion of the interference surface engages a corresponding portion of the driving recess. Upon further insertion, a tight friction fit occurs between such interference surface and its corresponding driving recess portion. This friction fit is sufficient to carry the driven member to its desired installation site. When the installation site is reached, the driven member is installed by rotationally driving such member with the driver end.
  • the device for carrying and driving an implant includes an internal connection dental implant with a driving recess comprised of a plurality of concave and convex lobes defining the driving surfaces.
  • the driver end for this embodiment includes an external surface with substantially matching lobes and driving surfaces for insertion into the driving recess.
  • the external surface of one or more of the driver end lobes is provided with an interference rib or portion extending outwardly from the exterior surface thereof.
  • the method of making and/or using the implant carry/driver device of the preferred embodiment includes providing a carrier having a driving configuration substantially matching the driving configuration of the driving recess and an interference rib or portion on the external surface of the driver in which the radial dimension of the driver end at the interference rib is greater than the radial dimension of the corresponding portion of the driving recess. A portion of the interference rib is then removed to form the interference surface.
  • the method of using the implant carry and driver device includes inserting the driver into the driving recess until the interference surface is sufficiently engaged with a corresponding lobe of the driver recess, carrying or delivering the engaged implant to the installation site and rotating the implant at the site with the driver.
  • the carry and drive device for the abutment screw in accordance with the preferred embodiment is designed to carry and drive an abutment screw having a driving recess and a driving configuration comprised of a substantially square cross-section.
  • the exterior configuration of the driver end of the carry and drive device for such abutment screw substantially matches the driving configuration of the abutment screw, but with one or more interference surfaces formed at its corners. Such interference surface inclines or is beveled inwardly toward its distal end.
  • the interference surface of the carry and drive device for the abutment screw has a radial dimension at its distal end which is less than the radial dimension of a corresponding corner portion of the driving recess in the abutment screw and a radial dimension at its proximal end which is greater than the radial dimension of a corresponding corner portion of the driving recess in the abutment screw.
  • the distal end of the carry and drive device is inserted into the driving recess of the abutment screw until there is engagement between the interference surface and a corresponding corner portion of the driving recess. Upon further insertion, sufficient frictional engagement is provided between such interference surface and the corresponding portion of the driving recess to carry the abutment screw to its installation site. Upon reaching the installation site, the abutment screw is positioned within the abutment and rotated by the driver end.
  • the carry and drive device in accordance with the preferred embodiment of the present invention is designed for use with a dental implant or a dental implant component such as an abutment screw which includes a driving recess with one or more drive surfaces.

Either an interior surface portion of the recess or an exterior surface portion of the driver end is provided with an interference surface.
  • At least a portion of the interference surface is positioned radially inwardly of the interior surface of the recess (or radially outwardly of the exterior surface of the driver) so that upon insertion of the driver end into the driving recess, frictional engagement or interference will result.
  • This enables the driver end and the implant (or abutment screw) to be frictionally engaged to permit the implant or abutment screw to be carried to the installation site and then rotated.

  • the driver end 12 is designed for insertion into a driving recess 15 near the proximal end of the implant 11 .
  • insertion of the end 12 into the recess 15 results in frictional engagement between portions of the end 12 and the recess 15 to permit the implant 11 to be carried from a sterile package or other environment to the installation site and, when so delivered, to install the implant by rotation.

  • the pilot end 21 is a short, generally cylindrical portion which is positioned at the distal end of the driver end 12 and is designed for insertion into the pilot bore 19 of the implant 11 . This insertion ensures proper seating of the lobes 24 and 25 relative to the lobes 16 and 18 and provides stability between the driver end 12 and the implant 11 during rotational installation of the implant 11 .
  • a lead-in or beveled surface 26 is provided at the distal end of the pilot end 21 to assist in locating and positioning the driver end 12 within the recess 15 and within the pilot bore 19 .
  • an interference means or mechanism in the form of the interference rib or portion 28 and the interference surface 29 is formed on each of the convex lobes 24 of the portion 22 .
  • the interference rib or portion 28 comprises a rib or portion which extends outwardly from the outermost portion of the convex lobes 24 so that the radial dimension “A” ( FIG. 4 ) at the outermost point of the ribs 28 is greater than the radial dimension “B” ( FIG. 2 ) defining the outermost ends of the concave lobes 16 of the recess 15 .
  • the “radial dimension” shall mean the radial distance between such rib, surface, lobe, etc. and its corresponding longitudinal axis.
  • the interference surface 29 on each of the lobes 24 is defined by a beveled surface which extends from a point 30 (the proximal end of the surface 29 ) on the interference rib 28 to the distal end 31 of the surface 29 .
  • this interference surface 29 is beveled or slopes inwardly from its proximal end 30 toward its distal end 31 so that the radial dimension “C” ( FIG. 4 ) of the surface 29 at its distal end 31 is less than the radial dimension “B” of the corresponding concave lobe 16 ( FIG. 2 ).
  • the surfaces 29 are substantially flat, planar surfaces, although they can, if desired, be surfaces which have a slight curve. Such slight curve can be either a slight axial curve (either concave or convex) or a slight radial curve (either concave or convex).
  • the extent to which the end 12 can be inserted into the driving recess 15 beyond the initial contact point between the interference surface 29 and the proximal end of the concave lobes 16 is dependent upon various factors including, the materials from which the implant 11 and the driver 12 are constructed, the radial dimension “A” of the interference rib 28 , the radial dimension “C” of the distal end 31 and the point along the surface 29 at which initial contact with the lobe 16 is made. In the preferred embodiment, it is desirable for the end 12 to be inserted into the recess 15 as far as possible without the distal ends of the lobes 24 and 25 “bottoming out”.
  • Insertion of the driver end 22 into the recess 15 should also preferably be a distance which is sufficient to allow the pilot 21 ( FIG. 5 ) to be seated within the pilot bore 19 of the implant 11 .
  • This provides stability and proper alignment and engagement between the driving surfaces of the driver and implant lobes during rotation of the driver, and thus the implant.
  • initial engagement between the surface 29 and the distal ends of the lobes 16 should occur when the end 12 is inserted between about 20 and 80% and more preferably, between about 30 and 70%.
  • the carry and drive device 10 is manufactured by forming the driver end 12 with the interference ribs 28 extending the entire length of the lobes 24 . Following this, the surfaces 29 are formed by removing a portion of the ribs 28 and a portion of the distal ends of the convex lobes 24 so that the radial dimension “C” ( FIG. 4 ) is less than the radial dimension “B” ( FIG. 2 ) and the initial point of engagement between the surface 29 and the distal ends of the lobes 16 upon insertion of the end 12 occurs at a point between the distal and proximal ends of the surface 29 .
  • each of the convex lobes 24 is provided with an interference rib or portion 28 and a corresponding interference surface 29 .
  • ribs and surfaces could be provided on less than all of the convex lobes 24 .
  • providing interference ribs and corresponding interference surfaces on fewer of the lobes 24 will result in a lesser carrying force.
  • benefits of the carrying feature of the present invention can still be achieved with a structure in which at least one of the convex lobes is provided with an interference rib 28 and a corresponding interference surface 29 provided the dimensional relationship between such surface and corresponding lobe is sufficient to provide the desired carrying force.
  • an interference rib and a corresponding interference surface could be formed on the concave lobes 25 of the lobed configuration 22 .
  • the interference surface would engage the convex lobes 15 of the recess 15 and result in a frictional fit between those elements. Such a structure would still provide sufficient carrying force between the device 10 and the implant 11 .
  • one or more lobes of the implant 11 could be provided with an interference rib and a corresponding interference surface.
  • the rib and surface of the implant lobes would frictionally engage corresponding portions of the driver lobes 24 and/or 25 .
  • the radial dimensions of the proximal and distal ends of the interference surface would be compared to the radial dimension of the corresponding driver lobe.
  • the proximal end of the implant interference surface would be greater than the radial dimension of the corresponding driver lobe and the radial dimension of the distal end of the implant interference surface would be less than the radial dimension of the corresponding driver lobe.
  • implant 11 is an internal connection implant with an internal driving recess
  • the invention is equally applicable to an externally driven implant in combination with a driver having an internal driving recess.
  • the invention can be characterized as a dental implant carry and drive assembly in which either the implant or the driver includes an inner driving recess having one or more drive surfaces or lobes and in which the other of the implant or the driver includes an exterior configuration substantially matching the configuration of the inner driving recess and having one or more corresponding driving surfaces or lobes. Further, at least a portion of the implant or driver is required to include interference means such as an interference surface, in which the respective radial dimensions of the interference surface and the corresponding lobe or drive surface with which it is engaged provide sufficient frictional engaging interference.
  • the end 12 is inserted into the driving recess 15 of an implant 11 .
  • this is when the implant 11 is still at least partially in its package or in some other sterile condition.
  • Such insertion is continued until sufficient frictional engagement is made between the surface 29 and the distal ends of the lobes 16 and until the pilot 21 is positioned within the pilot bore 19 .
  • the implant 11 is then carried by the device 10 to the installation site and the implant is rotated by the device 10 until it is installed to the desired position.
  • FIGS. 8-16 showing details of the carry and drive device for use with a dental implant component such as an abutment screw.

  • the carry and drive device shown in FIGS. 8-17 differs in many respects from the specific construction of the implant carry and drive device of FIGS. 1-7 , there are various features of the abutment screw carry and drive device which are common with the implant carry and drive device.
  • the driven element having a driving recess with one or more drive surfaces or lobes
  • a drive member having an exterior drive configuration substantially matching that of the driving recess and an interference surface formed on a portion of the exterior surface of the drive member.
  • the distal end of the interference surface has a radial dimension less than the radial dimension of a corresponding portion of the driving recess and the proximal end of such surface has a radial dimension greater than the radial dimension of a corresponding portion of the driving recess.
  • the carry and drive device 35 for the abutment screw is generally elongated and includes a driver end 36 and a rearward shank portion 38 for connection to a dental hand piece or other rotation means.
  • the driver end 36 is inserted into a driving recess 39 of an abutment screw 40 .
  • the abutment screw 40 includes a shoulder portion 41 and a threaded portion 42 for securing an abutment (not shown) to a dental implant.
  • insertion of the carry and drive end 36 into the recess 39 results in carrying engagement between the end 36 and the recess 39 so that the screw 40 can be removed from a package or other sterile environment and delivered to the installation site and, when there, be rotationally driven to secure the abutment to the implant.
  • the proximal end of the abutment screw 40 is provided with the driving recess 39 .
  • the recess 39 has a driving configuration which is roughly a square having four driving portions or driving lobes 44 .
  • Each of the driving portions or lobes 44 includes a driving surface or pair of driving surfaces 45 and a radial, end portion 46 .
  • the driving surface portions 45 comprise side surface portions of a substantially square configuration. Accordingly, the driving surfaces 45 on opposite sides of the end portions 46 are disposed relative to one another at approximately 90°. In the embodiment shown in FIGS.
  • the end portions 46 of the lobes or drive portions 44 have a radial dimension which is spaced a radial distance “D” ( FIG. 9 ) from the longitudinal center axis 33 of the recess 39 .

  • Lead-in or beveled surface portions 55 and 56 are provided at the distal end of the driver end 36 to assist in locating and positioning the end 36 within the recess 39 .
  • the driving recess 39 in the screw 40 is formed by first boring a cylindrical hole 48 and then forming the lobes or drive portions 44 via a “broach” process. Accordingly, the broaching process is utilized to form the drive surfaces 45 as well as the end surfaces 46 . As shown, the diameter of the cylindrical bore 48 is slightly larger than the lateral dimensions of the generally square configuration defined by the drive surfaces 45 ; however, this does not need to be the case.
  • One reason for first forming the bore 48 by conventional means such as drilling or machining is to remove as much material as possible prior to the broaching process to form the drive lobes or portions 44 .
  • the driver end 36 has a generally square cross-sectional configuration, with four generally planar side surfaces 49 .
  • these side surfaces 49 are drive surfaces which, when the end 36 is inserted into the recess 39 , engage the drive surface portions 45 to rotate the screw 40 .
  • the lateral dimension between opposite side surfaces 49 is slightly less than the lateral dimension between opposite drive surfaces 45 to allow the end 36 to be inserted into the recess 39 , but with a small enough tolerance so that, upon insertion, good driving engagement is made between the surfaces 49 and 45 .
  • each interference surface 50 Positioned between each adjacent side surface 49 of the end 36 is an interference surface 50 .
  • each interference surface 50 includes a distal end 51 and a proximal end 52 , with the distal end 51 being located at or near the distal end of the surfaces 49 and the proximal end 52 being located at or near the proximal end of the surfaces 49 .
  • the interference surfaces 50 are beveled and incline inwardly toward the axial center 37 of the end 36 as the surfaces 50 extend from the proximal end 52 to the distal end 51 .
  • these surfaces 50 are substantially planar surfaces, although they could also be slightly curved either radially (convex or concave) or axially (concave or convex). As shown best in FIG. 12 , this results in a structure in which the radial dimension “E” of the surface 50 at the distal end 51 is less than the radial dimension “F” of the surface 50 at the proximal end 52 .
  • interference surfaces 50 and the end surfaces 46 of the recess 39 is such that the radial dimension “E” at the distal end 51 of the surface 50 is less than the radial dimension “D” ( FIG. 9 ) of the end surface 46 and the radial dimension “F” of the surface 50 at the proximal end 52 is greater than the radial dimension “D” of the surface 46 .
  • the radial dimension of the surface 50 equals the radial dimension “D” of the end surfaces 46 .
  • the material from which the screw 40 is constructed (a titanium alloy) is softer than the material of the driver end 36 , such limited deformation will occur in the drive surfaces 45 . After installation of the screw 40 by rotation is complete, the driver end 36 is easily withdrawn from the recess 39 .
  • FIGS. 14-17 show the manner of using the device 35 to carry and drive the abutment screw 40 .
  • FIGS. 14 and 15 show the end 36 of the device 35 partially inserted into the recess 39 and to a point where the radial dimension of the surfaces 50 are substantially equal to the radial dimension “D” of the surfaces 46 . Then, upon further insertion to the point shown in FIGS. 16 and 17 , the surface 50 and the end surface 46 become frictionally engaged. This permits the screw 40 to be carried or delivered from its sterile package or other environment to its installation site and then installed by rotationally driving the screw 40 with the device 35 .
  • the carry and drive device of FIGS. 1-7 and the carry and drive device of FIGS. 8-17 also include a self-aligning feature which assists in quickly and easily causing the lobes or drive surfaces of the driver ends to be operationally aligned with their corresponding drive lobes in the implant 11 or the abutment screw 40 .
  • the means for accomplishing this includes lead-in or beveled surface portions at or near the distal ends of the carry and drive devices and their corresponding implant or screw surfaces and/or dimensional relationships between the driver ends and corresponding driving recesses.
  • FIGS. 18 and 19 showing cross sections of a misaligned driver end 12 ( FIG. 18 ) and an aligned driver end 12 ( FIG. 19 ). If the driver end 12 is inserted into the driving recess 15 of the implant 11 in a misaligned position as shown in FIG. 18 , the driver end 12 will be axially aligned with the driving recess 15 because of the beveled surface 26 and the fact that the outer diameter of the pilot end 21 closely matches the diameter “G” ( FIG. 2 ) defining the innermost surfaces of the convex lobes 18 . Accordingly, when the end 12 is initially inserted into the recess 15 , it is immediately axially aligned.
  • FIGS. 20 and 22 showing a misaligned driver end 36 relative to the recess 39 and FIGS. 21 and 23 showing an aligned driver end 36 relative to the recess 39 .
  • the driver end 36 will be immediately axially aligned as a result of engagement between the surface portions 55 and 56 at the distal end of the end 36 and the pilot bore 48 .
  • the drive end 36 upon rotation of the driver end 36 , engagement between the beveled surface 54 on the screw 40 and the radiused surface portion 55 on the driver end 36 , the drive end 36 will drop into the recess 39 , with the interference surfaces 50 aligned and engaged with the end portion 46 .
