Vial for dental implant delivery system

Abstract

A dental implant delivery system comprising a vial having two cavities. One cavity in the body of the vial houses an implant and a driver mount, and the other cavity in the lid of the vial houses a healing screw.

Description

BACKGROUND OF THE INVENTION

Threaded dental implants are typically packaged and shipped in a package known as an implant delivery system. The delivery system typically includes a vial containing the threaded implant, a driver mount, and a healing screw. The vial is then shipped in sterile packaging until the implant is needed during a surgical implantation procedure.

The vial usually has an elongated cylindrical configuration forming an inner cavity to hold the implant, driver mount, or healing screw. These three components may be transported in one or two vials. Typically, a lid fits on top of the vial to seal and retain the components in the cavity.

In order to install the implant during a surgical procedure, an implant site is prepared using conventional surgical procedures. Typically, an incision is made along the gingival tissue at the implant site, and a cylindrical bore is drilled into the bone. Once the site is fully prepared, the lid is removed from the vial, and the implant, driver mount, and healing screw are all removed. The healing screw is disconnected from the driver mount, and a driving tool, such as a motorized dental hand-piece, is connected to the free end of the driver mount using an adapter. The implant and driver mount are moved to the implant site, and the end of the implant is driven into the bore. The driver mount is then removed from the implant, and the healing screw is placed on the coronal end of the implant. The gingival tissue is then sutured and the implant remains within the bone for several months as osseointegration and healing occur. During a second surgical procedure, the implant is re-exposed, the healing screw is removed, and a dental prosthesis is affixed to the implant.

One important disadvantage associated with prior dental delivery systems using a single vial is that the healing screw is connected to the implant or driver mount. As a consequence, direct access to the implant or driver mount is not possible without first moving or removing the healing screw. Moving the healing screw adds unwanted time and surgical steps to the implantation procedure.

Some prior delivery systems use two separate vials or large, bulky containers having multiple cavities to hold the implant, driver mount, and healing screw. For example, some delivery systems store the healing screw in one container and the implant and driver mount in another container. Still other delivery systems have two separate cavities, for example a container having two side-by-side cavities. One cavity holds the implant and driver mount while the other cavity holds the healing screw. None of these systems use a single vial to hold the implant, driver mount, and healing screw. Instead, these.

It would be advantageous to employ a dental implant delivery system that utilizes a single vial that houses the implant, driver mount, and healing screw and that gives direct and simultaneous access to the implant and driver mount and healing screw. Such a delivery system would more effectively hold these components to reduce the time and number of steps during a dental implantation procedure. A surgical procedure requiring fewer steps ultimately would be less traumatic to the patient, more expeditiously performed, and less burdensome on the surgeon, to name a few examples.

Further yet, such a delivery system would minimize the amount of handling of the system components.

The present invention solves the problems discussed above with prior dental delivery systems and provides further advantages.

SUMMARY OF THE INVENTION

The present invention is directed toward a vial for a dental implant delivery system. The vial provides direct and simultaneous access to both the healing screw and the implant once a lid on top of the vial is open. When the lid is open, the driver mount and implant may be removed with a single step and the healing screw may be removed with a single step.

The vial has an elongated cylindrical configuration with a body portion forming a first interior cavity and a lid forming a second interior cavity. This first cavity houses the implant and the driver mount, and this second cavity houses the healing screw. The lid may be moved between a closed and open position. In the closed position, the lid covers the top of the body portion and seals the two cavities together. In the open position, the lid moves to a position adjacent the body portion and enables direct access to both cavities.

The invention, accordingly, comprises the apparatus and method possessing the construction, combination of elements, and arrangement of parts that are exemplified in the following detailed description. For a fuller understanding of the nature and objects of the invention, reference should be made to the following detailed description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1-4 depict a dental implant delivery system 10 comprising a vial 12, a threaded implant 14, a driver mount 16, and a healing screw 18.

Implant 14 may be any one of various implants known to those skilled in the art, such as a TWIST.TM. implant manufactured by Sulzer Calcitek Inc. of Carlsbad, Calif.

Driver mount 16 has a generally elongated cylindrical configuration having two ends 30 and 32, respectively. End 30 is configured to abut against the coronal end of the implant and includes a plurality of splines that project downwardly to engage corresponding splines of the implant. The engagement between these splines provides an anti-rotational connection between the driver mount and implant. This anti-rotational connection may be established with other configurations known to those skilled in the art, such as a mating hexagonal projection and recess.

The other end 32 of the driver mount includes a flange 34. This flange abuts against a shoulder on the interior of the vial and suspends the implant and driver mount. A retaining screw 36 connects the driver mount to the implant. The screw passes axially through end 32 and into a channel within the driver mount and engages threads located in a cavity in the implant.

Vial 12 has an elongated cylindrical body 38 forming an interior hollow cavity 40 housing the implant and driver mount. Cavity 40 extends from a top portion 42 toward a bottom portion 44.

Vial 12 further includes a clip 46 that extends along one side of the body. The clip is formed from a flexible arm that is able to securely attach and support the vial. The clip, for example, may attach the vial to the periphery of a dental surgical tray (not shown).

The vial also includes a lid 50 forming an interior cavity 52, separate from cavity 40 in body 38. The lid is connected to top portion 42 with a hinge assembly 54. The hinge assembly enables the lid to move from a closed position (shown in FIGS. 1 and 2) to an open position (shown in FIGS. 3 and 4). Preferably, the lid remains attached to the body of vial in the open position, as shown in FIGS. 3 and 4. As such, no refuse or secondary waste is generated when the lid is opened.

The lid may be connected to the body of the vial with various different attachments known to those skilled in the art. For example, a flexible arm (not shown) may connect the lid to the body of the vial. The arm could function as a spring and automatically bias the lid away from the body immediately after the lid is open.

Looking to FIGS. 1 and 2, in the closed position, lid 50 fits onto top portion 42 to enclose cavities 40 and 52. The connection between the lid and the top portion is sufficient to cover these cavities. In alternative embodiments, the lid may seal these cavities and maintain them in a sterile environment.

Further, in the closed position, healing screw 18 is directly above the implant and driver mount. In this position, the screw, implant, and driver mount are housed within a single cavity comprising cavity 40 and cavity 52. A separate vial or container for the healing screw is thus not needed.

As seen in the FIGS. 1 and 3, healing screw 18 connects to a delivery cap 60. This cap holds the healing screw in lid. When the lid is in the closed position, as seen in FIG. 1, the delivery cap abuts against end 32 of the driver mount to stabilize the implant, driver mount, and healing screw. Alternatively, a small gap (not shown) may be provided between the delivery cap and end 32. In both embodiments, the spacial relationship between the delivery cap and the driver mount minimizes movement of these components during shipping and handling of the vial.

One important advantage with the present invention is that a single vial houses both the implant and the healing screw, and once the vial is open, simultaneous access to both the implant and the screw is possible.

As shown in FIGS. 3 and 4, in the open position, the lid is adjacent top portion 42 of the body of the vial. One opening 62 gives access to the healing screw, and a second opening 64 gives access to the implant. Thus, a single action of opening the lid provides immediate access to both the healing screw and the implant. Openings 62 and 64 are adjacent each in the open position to facilitate access to each cavity. Preferably, these openings reside in a common plane or closely residing planes. The separate cavities also expedite the implantation procedure.

Use of the implant delivery system is now discussed in more detail with reference to FIGS. 1-4. During storage and transportation of the implant delivery system, the implant, driver mount, and healing screw remain in a protected environment in the vial. During a dental implantation procedure, lid 50 is opened. The implant is exposed in one cavity, and the healing screw is exposed in another cavity. A driving tool, such as a motorized driver or ratchet wrench, and an adapter are then affixed to end 32, and the implant and driver mount are removed from the vial. The distal end of the implant is then positioned into the osteotomy site. The driving tool then imparts a driving force to the driver mount that, in turn, imparts this same force to the implant.

Once the implant is fully seated and positioned, the driving tool is removed from end 32. A separate removal tool is then used to loosen and remove retaining screw 36. The driver mount is removed from the implant. The noted driving tool is then used to remove the healing screw from cavity 52. Using the same driving tool to remove and drive both the driver mount and healing screw reduces the overall number of surgical steps in the implantation procedure. This driving tool is affixed to the end of delivery cap 60, and the cap and screw are simultaneously removed from cavity 52. The cap and screw are then placed over the coronal end of the implant until the screw fits within the implant. Thereafter, the cap is disengaged from the screw, and the screw is left to cover the implant. Conventional procedures are then used to finish the surgical procedure and thereafter connect a prosthesis to the implant.

In alternate method, once the implant is fully seated and positioned, the driving tool is removed from end 32. A separate removal tool is then used to loosen and remove retaining screw 36. The driver mount is removed from the implant. The separate removal tool is then used to remove the healing screw from cavity 52. Using the same removal tool to remove and drive both the driver mount and healing screw reduces the overall number of surgical steps in the implantation procedure. This removal tool is affixed to the end of delivery cap 60, and the cap and screw are simultaneously removed from cavity 52. The cap and screw are then placed over the coronal end of the implant until the screw fits within the implant. Thereafter, the cap is disengaged from the screw, and the screw is left to cover the implant. Conventional procedures are then used to finish the surgical procedure and thereafter connect a prosthesis to the implant.

Since certain changes may be made in the above-described apparatus and method without departing from the scope of the invention herein involved, all matter contained in the description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
