Dental implant packaging

Abstract

A dental implant packaging system for contamination-free packaging, storage, transport and delivery of dental implants and related components. Various embodiments of the system as applied to a dental implant and its cover screw are shown in which a dental implant is housed in a transparent tubular capsule that is lined with a titanium sleeve which covers the head and part of the body of the implant, leaving the tail end exposed to view. The head is restrained in the opening into the capsule and a cap which closes the capsule also serves to hold the head in place.

Description

BACKGROUND OF THE INVENTION

This invention relates in general to dental implants, and more particularly to contamination-free packaging, storage and transport and delivery of dental implants and related components as a unit for improved convenience to the dental practitioner.

U.S. Pat. No. 5,062,800 describes a dental implant package which includes a two-part handle that can be attached to the implant inside the package, adding the weight and cost of the handle to each package.

U.S. Pat. No. 4,763,788 describes a hermetically-sealed glass capsule enclosing a dental implant in an inner sleeve that is axially longer than the implant and is made of the same material as the implant and is held in place in the capsule by a spring that is also contained in the sealed capsule. This package is opened by breaking the glass capsule.

GENERAL NATURE OF THE INVENTION

According to the present invention in one of its unique aspects a dental implant package has two compartments for simultaneous delivery of a dental implant and a related component, such as a healing screw, to the dental practitioner. In this package the openings to the two compartments are preferably coplanar so that they can be closed with a common cover. To this end each compartment may be attached at its open end to, and open through an aperture in, a relatively stiff substantially planar support, and the common cover may be peripherally sealed to that support. The compartment reserved for the dental implant may contain a sleeve made of the same material as the implant, but owing to the improved design of the present invention that sleeve may be axially shorter than the implant fixture, thereby saving weight and the cost of unnecessary material. The compartment reserved for the related component may be axially shorter than the implant compartment. Desirably, the package includes structural members for holding the two compartments in prescribed relative positions, and to facilitate the handling of the package while the common cover is being removed and the contents are being extracted from their respective compartments.

In a further improvement the invention provides a sealable container for the implant package, which protects the implant package from damage during storage and transport, and provides a second shield against contamination. Conveniently, like the implant package, this container has an open side and may be fitted with a cover that is peripherally sealed to that open side.

In another aspect of the invention the implant compartment is provided with a unique cover. One embodiment of this cover includes storage for a cover screw. Another embodiment includes a holder for releasably grasping a cover screw attached to one end of the implant fixture within the compartment In practicing this aspect of the invention the package may omit the second compartment.

DETAILED DESCRIPTION OF THE INVENTION

The invention is explained in greater detail with reference to the accompanying drawings, in which:

FIG. 1 is a side view of a first embodiment of the invention;

FIG. 2 is a view from the underside of FIG. 1;

FIG. 3 is an end view of FIG. 1;

FIG. 4 is a partial top view of the other side of FIG. 1;

FIG. 5 is an exploded view of the package of FIG. 1 and a container for that package;

FIG. 6 is a partial longitudinal section view of a second embodiment of the invention; and

FIG. 7 is a partial longitudinal section view of a third embodiment of the invention.

Referring now to FIGS. 1-4, inclusive, a package 10 for a dental implant 12 and a related component 14 has two separate compartments 16 and 18, for containing the implant and the related component, respectively. Each compartment has a top opening 22, 24, respectively through a common substantially planar support 20. The support 20 is recessed in a peripheral frame 26, to which a cover 28 can be peripherally attached. The implant 12 is held in a sleeve 36 which in turn is supported within the top portion of the first compartment 16, extending from the opening 22 part way into this compartment. The sleeve 36 may have a preferably slot-like aperture (not shown) along the side to provide a view of the implant 12. Generally according to current practice the implant is made of titanium or a dilute alloy of titanium, and the sleeve 36 is made of the same material. In the present invention the sleeve is shorter than the implant, as appears in FIG. 1. The related component 14, which as here illustrated is a cover screw for the implant, is held in the second compartment 18, which is provided with a widened top portion 34 for the head of the cover screw. A side panel 38 is connected end-wise to the frame 26. These parts 26 and 38 may be rectangularly connected, as shown. A buttress panel 40 is peripherally joined to the side panel and the second compartment.

Referring now to FIG. 5, a container 50 has a pocket 52 adapted to receive the implant package 10, lying on a side as shown. The container 50 has a relatively stiff frame 54 around the pocket, and a removable cover 56 which is adapted to be attached to the frame. The parts 12 and 14 are first sealed in the implant package 10, which is then sealed in the container 50. This packaging structure provides a double seal for parts which are sterile, in which the parts can safely be stored, transported and delivered to a user with sterility and structure intact. When preparing to place the implant in a patient, the dental practitioner will first remove the implant package 10 from the container 50. Then, by merely removing the cover 28 from the implant package, the practitioner will have the implant prepared for placement, without removing it from the container 10 until ready to place it.

In FIG. 6 the two parts 12 and 14 are assembled into a unit for storage, transportation and delivery. An implant package 66 has a screw-on cap 64. A holder 62 for the assembled unit 12, 14 has means 68 to grasp the head 32 of the cover screw 14. The holder has a shoulder 70 which stops against the top 72 of the package 66 and is surrounded by the cap 64 which when screwed down on the package holds the shoulder 70 against the stop 72. The implant 12 and attached cover screw 14 are thereby held within the package 66. To access the implant and its cover screw the cap 64 is unscrewed and the holder 62 is grasped to remove them from the package. The head 32 is held by friction in the grasping means 68 of the holder, which can be used to carry the implant to a desired location, and can be removed as desired. In this embodiment of the invention the sleeve 36 is omitted.

In FIG. 7 the two parts 12 and 14 are carried separately, one in the container 86, and one in the screw-on cap 76. A titanium sleeve 84 in the top part of the container encloses the implant 12, like the sleeve 36 as in FIG. 1. When screwed down the cap 76 presses the implant against a stop 82 at the top of the sleeve. A compartment 78 is provided in the cap, similar to the compartment 18, 34 in FIG. 1, for receiving the cover screw 14 and its head 32. A removable plug 74 in the top of the cap holds the cover screw in place in the cap until it is needed.

The container 50 can be modified to provide a double seal for the embodiments shown in FIGS. 6 and 7.

The compartments 16, package 66 and package 86 may be furnished with scalar markings, e.g: notch 90 in FIGS. 1 and 7, to indicate the length of the implant 12 contained in it.
