This invention relates to the packaging of dental appliances, particularly orthodontic appliances, and to the organizing of the appliances for their loading onto set-up trays. The invention particularly relates to methods of packaging and organizing of the appliances and of loading set-up trays with the appliances, and to the packages, organizers and set-up trays and appliance packaging, loading and organizing systems.
In the practice of dentistry, the efficient use of a dentist's time is enhanced by preparing the equipment and supplies needed by the dentist for a scheduled patient visit in advance of appointment, so that the dentist may proceed directly with an examination or treatment. The preparation is typically done by a technician or assistant on the dentist's staff. As a result, the dentist may see more patients in a specified period of time than would be possible if the dentist were to personally assemble the items.
Orthodontic practitioners, for example, have a number of examination or treatment activities, each of which may require different tools or supplies. A common task for an orthodontist is the installation of an orthodontic appliance on a patient. Currently, a most effective and widely used orthodontic appliance is an orthodontic brace that is formed of an archwire and a number of orthodontic brackets. Installation of such an appliance typically involves the bonding of the individual brackets of a set onto corresponding teeth of the patient. For such an installation, a set of brackets must be assembled for the orthodontist, along with adhesives, primers and other chemical substances, plus tweezers, curing light guns and other tools needed for the appliance installation.
The installation of a bracket-archwire appliance requires careful selection and placement of individual brackets from a supply onto the teeth usually in a one-by-one transfer of the brackets from the supply to the patient. The transfer involves the engagement of the correct bracket for a given tooth and the proper orientation of the bracket for placement on the appropriate tooth. Since the brackets are each tooth-specific, with each having a geometry specially configured to fit the surface of a tooth and to engage an archwire to exert specific forces on the tooth, an error in the selection of a bracket can be costly in terms of treatment time and loss of treatment quality.
Placement of a bracket on a tooth requires the orthodontist to hold the bracket, usually with a pair of tweezers designed for that purpose, with the base of the bracket coated with adhesive and oriented for placement against the patient's tooth. Each bracket base may be considered as having four sides, one intended as the gingival side that must face the gum when mounted on the tooth and one intended as the opposite occlusal side which will face the occlusal plane. At right angles to these are the mesial and distal sides, which will face the mesial and distal sides of the tooth, respectively. This requires proper orientation of the bracket in the hand of the orthodontist, with the gingival side facing downward for lower teeth and facing upward for the upper teeth.
Historically, an orthodontist stocks a plurality of brackets for each tooth, with the brackets often supplied loose in boxes. Each bracket was retrieved from a respective one of the boxes and oriented for application to the patient's tooth. When the orthodontist undertakes to retrieve the brackets from the boxes at chair-side, considerable professional time is consumed, while care must be taken to insure that the correct bracket is retrieved for a given tooth and is oriented correctly to have its pad coated with adhesive and applied to the tooth. The orthodontist will typically stock one type or model of appliance that is most commonly suitable for a patient, plus alternative types or sizes for use as the case may indicate.
The trend toward the use of a set-up tray has resulted in better use of the orthodontist's chair-side time in installing orthodontic appliances. This time has been replaced by technician or assistant time in loading the set-up trays employing many of the same motions and careful attention previously employed by the orthodontist. Set-up trays are usually hand-size trays or cards having compartments or sticky adhesive-coated pad areas to hold the individual appliances in a predetermined arrangement for pick-up by the orthodontist at tray side. Set-up trays of the type that not only hold the brackets for the orthodontist but present tooth-specific, single-doses of adhesive for use with each respective bracket are described in U.S. Pat. Nos. 6,213,767 and 6,482,003. Simpler set-up trays that hold only the brackets are also common.
Whether done by the practitioner or the practitioner's assistant, the efficiency of dental practice and the reduction of error occurrence can be improved by better ways for supplying and handling dental supplies.
One aspect of the invention is an orthodontic appliance organizer. The orthodontic appliance organizer includes a storage component for storing an orthodontic appliance. The orthodontic appliance organizer includes an organizer tray that has a first panel and a hinged second panel coupled to the first panel. The hinged second panel includes a plurality of appliance holders thereon, each appliance holder having structure for holding an orthodontic appliance. In addition, the hinged second panel rotates relative to the first panel for providing access to the storage component of the orthodontic appliance organizer.
Another aspect of the invention is an orthodontic appliance organizer. The orthodontic appliance organizer includes a set-up tray support member for supporting a set-up tray. The orthodontic appliance organizer also includes an organizer tray having support for the set-up tray support member thereon. The organizer tray includes a plurality of appliance holders having structure for holding the orthodontic appliances. The orthodontic appliance organizer also includes a storage component having a top for supporting the organizer tray. The storage component also includes a side extending transversely relative to the top including compartments for storing the orthodontic appliances and allowing the user to access and transfer the orthodontic appliances between the storage component and the organizer tray.
In another aspect of the invention is an orthodontic appliance organizer. The orthodontic appliance organizer includes an organizer tray defining an aperture therein and including a plurality of appliance holders. The appliance holders have structure to hold the orthodontic appliances. The orthodontic appliance organizer also includes a storage component supporting the organizer tray. The storage component defines a recess that can be accessed by a user through the aperture in the organizer tray. The storage component also has storage compartments corresponding to appliance holders in the organizer tray. The combination of the organizer tray and the storage component when supporting the organizer tray aligns the aperture and the recess to define a bin.
In most dental practices, a set-up tray of some sort is prepared by a dental assistant and placed at chair-side next to a patient before the dental practitioner enters the treatment area for a dental appointment. This is particularly true in orthodontic practices for appointments to install orthodontic appliances on patients. In such orthodontic practices, an orthodontic set-up tray is typically loaded with orthodontic appliances that have been pre-selected by the practitioner for treatment of a patient for whom an appointment has been scheduled to install the appliance. One of several such prior art set-up trays that are in use by orthodontists is illustrated in
In
The brackets 30 have pads or bases 31 to which is attached or integrally formed a bracket body 32 that is typically composed of a pair of tie wings 33 in which is formed a generally horizontal archwire slot 34. As illustrated in
The packages 20 have a plurality of the cavities 25 in a line. For brackets of more often used prescriptions, the number of cavities 25 in the plurality is typically seven to ten. The packages 20 may be made with other numbers of cavities 25. Three to five brackets per package may be a practical number, particularly for brackets of less often used appliance prescriptions.
According to a method of the present invention, brackets 30 are loaded onto a set-up tray 10 from the carriers 20 by personnel at a treating orthodontic practitioner's office with the use of an organizer 40, illustrated in
The organizer tray 41 has a four-sided, set-up-tray-receiving recess 43 formed at its center and a plurality of appliance holders 44. The holders are in the form of three-sided, open-ended, carrier-receiving recesses or slots 44, half of which are formed along one side of the organizer tray 41 and half formed along the opposite side of the organizer tray 41. The holders 44 are configured to hold the appliances 30, preferably in packages of appliances, such as the carriers 21. The number of the carrier-receiving recesses 44 is equal to the maximum number of brackets 30 that will form an orthodontic brace, typically twenty-eight.
As illustrated in
The base 42 contains hollow storage compartment 51-53, as illustrated in
The organizer tray 41 forms a cover to the compartments 51-53 in the base 42, and slides over the base 42 with its outer edges along sides 46 and 47 fitting into grooves 54 along the sides of the base 42 adjacent compartments 52 and 53, respectively. The organizer tray 41 is shown in its closed position over the base 42 in
Further, a lid 50 may be provided to cover the organizer tray 41 so that the entire organizer 40 can be stored when partially empty carriers 21 are present in the slots 44 of the organizer tray 41. This allows the organizer 40 to be stored in any condition at the office of the orthodontic practitioner. Typically, a slotted cabinet or rack (not shown) is provided at the practitioner's office for storage of organizer trays 40 containing different bracket prescriptions or types.
The use of the organizer 40 is illustrated in
The organizer tray 41 is, in the preferred embodiment, loaded with supplies of brackets 30 from the compartments 52 and 53 beneath the corresponding slots 44 of the tray 41. This loading is carried out by removing one of the packages or carriers 21 from the compartment 52 or 53 and sliding the flanges 27 of the carriers 21 into the slots 45 of the tray 41, with the handles 26 of the carriers 21 facing away from the recess 43 that holds the set-up tray 10. In an alternative embodiment, the carriers 21 and the holders 44 may be configured so that the appliances 30 can be transferred from the alternatively configured versions of the packages 21 to alternatively configured versions of the holders 44, with their orientations preferably preserved in the transfer.
When a set-up 10 tray is loaded as described above, an orthodontist may hold the set-up tray 10 with the centerline horizontal and the side holding the bracket mounting areas 13 facing the patient, and then similarly transfer the brackets 30 with tweezers onto the teeth of the patient. Such transfer requires only rotating the pad 31 of the bracket 30 from a horizontal to a vertical plane. Further reorientation of a bracket 30 is not necessary to place the bracket 30 in its correct orientation for mounting on the patients tooth

The set-up tray support member 64 holds a set up tray for preparing the orthodontic appliances for application to the teeth of the patient. The set up tray can hold adhesive, tools, and help keep the orthodontic appliances positioned for application. The set-up tray support member 64 of the illustrated embodiment is formed of a plastic or rubber material, however, other embodiments use other types of materials. The set-up tray support member 64 includes a rim 70. The rim 70 interacts with the organizer tray 66 to support the set-up tray support member 64 when the set-up tray support member 64 is placed upon the organizer tray 66. The set-up tray support member 64 defines a recessed area 72 for supporting a set-up tray (not shown). The recessed area 72 also cooperates with the rim 70 for providing sufficient structure for maintaining the original orientation of the set-up tray support member 64 when placed upon the organizer tray 66. In addition, the structure enables the stacking of multiple set-up tray support members 64 as described in further detail hereinbelow with respect to
The organizer tray 66 is designed with a plurality of appliance holders 76 formed therein designed to receive the carriers 21. In the illustrated embodiment, the appliance holders 76 are arranged on opposite sides of the organizer tray 66. The organizer tray 66 is divided into three sections or panels. The first panel 78 is the central panel that includes an aperture 80 formed therein. The set-up tray support member 64 covers at least a portion of this aperture 80 when placed upon the organizer tray 66. The first panel 78 does not define any appliance holders 76. The first panel 78 also includes slots 82 for facilitating the combination of the organizer tray 66 with the storage component 68. Moreover, the combination of the first panel 78 and the storage component 68 forms a bin 84 having side walls 86 and a curved recess 88. The curved recess 88 corresponds to the aperture 74 defined in the set-up tray support member 64. Thus, the dental professional can easily place their fingers through the aperture 74 and into the curved recess 88 for lifting the set-up tray support member 64 off of the organizer tray 66. The bin 84 is generally used to store set-up trays in the illustrated embodiment, however, other items can be stored in the bin 84 in other embodiments. The first panel 78 also includes plateaus 90 that are designed to cooperate with areas on the storage component 68 to facilitate stacking of multiple ones of the orthodontic appliance organizer 62.
The organizer tray 66 also includes a second panel 92 and a third panel 94 defining a plurality of appliance holders 76 defined therein. The appliance holders 76 are open along the top surface 96 of the second panel 92 and the top surface 98 of the third panel 94 to enable visual inspection by the dental professional. In addition, the appliance holders 76 are designed to enable the carriers 21, or other similar device, to be slid in and out with ease. There are fourteen appliance holders 76 on each one of the panels 92, 94 of the organizer tray 66 corresponding to the fourteen teeth on the upper arch and the lower arch. Accordingly, the organizer tray 66 positions the carriers 21, or other device, so that the orthodontic appliances for a specific tooth are in an appliance holder 76 for that spot. The second and third panels 92, 94 are hinged around axes defined by the intersection of the first panel 78 with the second and third panels 92, 94. The second panel 92 rotates clockwise from the position illustrated in
The storage component 68 includes a plurality of storage compartments 100 used to hold a plurality of packages 20 or other similar assemblies. Each one of the storage compartments 100 corresponds to an appliance holder 76 on the organizer tray 66. The storage component 68 also includes a recess 102 designed for providing space for formation of the bin 84 by combining the first panel 78 of the organizer tray 66 and the storage component 68. The storage component 68 includes ridges 104 that cooperate with the slots 82 of the organizer tray 66 for rigidly combining the organizer tray 66 to the storage component 68. The storage component 68 also includes shelves 106 that help define the storage compartments 100 that are appropriately spaced to hold the packages 20 or similar assemblies. The storage component 68 also includes flanges 108 upon the bottom that are useful in stacking multiple ones of the orthodontic appliance organizer 62 described in more detail hereinbelow with respect to
In use, the orthodontic appliance organizer 62 enables quick and easy application of the orthodontic appliances to a patient's mouth. Moreover, the design simplifies the process for the dental professional to restock and arrange their orthodontic appliance inventory. Initially, the storage component 68 is filled with a plurality of packages 20 containing the orthodontic appliances. In the illustrated embodiment, the storage component 68 is designed to be able to hold four packages 20 stacked one upon each other. Those skilled in the art recognize that other embodiments can hold a different number of packages 20 in the storage component 68. Furthermore, other types of orthodontic appliance packages 20 are used besides those described in
After the storage component 68 is filled with packages 20 or similar assemblies, the organizer tray 66 is placed onto the top 67 of the storage component 68 by aligning the aperture 80 with the open space 102. The bin 82 is formed by the combination of the first panel 78 of the organizer tray 66 and the storage component 68. The bin 82 is sized for filling with set-up trays. Other embodiments fill the bin 82 with other materials and fill the recess 102 or the bin 82 at other times. The slots 82 and the ridges 104 cooperate securely attaching the organizer tray 66 to the storage component 68. The set-up tray support member 64 is then placed over the aperture 80 of the first panel 78 of the organizer tray 66 concealing the set-up trays. The rim 70 of the set-up tray support member 64 is larger than the aperture 80 and therefore provides structure for supporting the set-up tray support members 64. The orthodontic appliance organizer 62 is then ready for use by a dental professional.
The dental professional places the orthodontic appliance tray 62 in a location near the patient. The dental professional removes one of the carriers 21 from the packages 20 located in the storage component 68. The storage component 68 enables lateral access of the carriers 21 because the storage compartments 100 are open around the sides 114 extending transversely to the storage component 68. The removed carrier 21 is slid into the appliance holder 76 positioned directly above the dedicated one of the storage compartments 100 that the carrier 21 was removed from. Each carrier 21 corresponds to an individual tooth that will be handled by the dedicated appliance holder 76 placed directly above the dedicated one of the storage compartments 100. Therefore, keeping the orthodontic appliances organized by tooth is very simple because of the design of the storage component 68 and organizer tray 66. In addition, the dental professional can easily move and organize their inventory based on the design. As in the embodiments illustrated in
The dental professional can then pull out the set-up tray support member 64 using the aperture 74. The dental professional grabs one of the set-up trays stored inside of the bin 84. The set-up tray support member 62 is placed right back over top of the aperture 80 and the set-up tray is placed inside of the recessed area 72 of the set-up tray support member 64. The dental professional can then remove orthodontic appliances and transfer them to the set-up tray for preparation and application to a dedicated tooth.
Each carrier 21 of the illustrated embodiment holds ten brackets for use on the same tooth. In addition, the illustrated embodiment has a storage component 68 that holds four packages 20 each containing a carrier 21. Therefore, the orthodontic appliance organizer 62 of the illustrated embodiment holds enough orthodontic appliances for forty patients. Replacement and restocking the orthodontic appliance inventory is a simple procedure. Once the orthodontist or other dental professional has gone through forty patients, the second panel 92 and third panel 94 are rotated for providing access to the storage compartments 100 of the storage component 68. The plastic covers 28 remain inside of the storage compartments 100 and can be removed or reused. New sets of packages 20 or carriers 21 are placed into the storage compartments 100 of the storage component 68 enabling additional patients to be serviced by the orthodontic appliances contained therein.
