Ornamental tooth decorations and methods for forming the same

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to ornamental tooth decorations. More particularly, the present invention is directed to the encasement of gemstones and other ornamental tooth decorations into a clear material enabling the ornamentation to be clearly seen, and which can be non-invasively bonded to the exterior surface of a tooth and methods for forming the tooth ornaments.

[0003] 2. Description of the Related Art

[0004] The conventional art of tooth ornamentation is invasive to the tooth. Normally the tooth is drilled to create a concavity in which to embed a tooth ornament. The tooth ornament is normally encased in a mounting of metal structure, which is generally a precious metal.

[0005] The art of tooth ornamentation has been used as an additional ornamentation to the body for the purpose of fashion, fad, trend or personal enjoyment. Ear piercing, body piercing, tattooing, nail decorating and ornamentation such as earrings, bracelets, necklaces have been popular for a considerable amount of time. Although tooth ornamentation has been popular for many years, live teeth have been at possible risk from drilling into the tooth to make the concavity for the tooth ornament.

SUMMARY OF THE INVENTION

[0006] In an illustrative, non-limiting embodiment of the invention, an ornament for a tooth is provided, in which a decorative portion is encased by and adhesively secured by a clear sealant/resin portion. The tooth ornament can be non-invasively bonded to any live or artificial tooth for temporary ornamentation of the tooth. The tooth ornament will eventually be dislodged by normal use of the tooth or may be removed as desired by a dental professional. The length of time before the tooth ornament is dislodged naturally depends on the particular use of the tooth.

[0007] In another illustrative, non-limiting embodiment of the invention, an ornament for a tooth is provided, which includes first, second, and third layers of clear sealant/resin and a decorative portion. The first clear sealant/resin layer is adhesively formed on a clean, smooth flat surface and has a concavity. The second clear sealant/resin layer is adhesively formed in the concavity of the first clear sealant/resin layer. The decorative portion is adhesively formed on the second clear sealant/resin layer, and the third clear sealant/resin layer is adhesively formed over the decorative portion and the first and second clear sealant/resin layers, such that the sealant/resin layers form an encasement of the decorative portion.

[0008] In another illustrative, non-limiting embodiment of the invention, a method of forming a tooth ornament is provided. The method includes: placing a first droplet of a clear, adhesive, light-curing sealant/resin on a smooth flat surface; light-curing the first droplet; drilling the light-cured first droplet with a milling tool to form a concavity in the light-cured first droplet; placing a second droplet of the clear, adhesive, light-curing sealant/resin into the concavity; positioning a gemstone into the second droplet and the concavity; light-curing the second droplet, after the gemstone is positioned; forming a plurality of layers of the clear, adhesive, light-curing sealant/resin on the light-cured first and second droplets and the gemstone; and light-curing each of the plurality of layers, after each of the plurality of layers is formed.

[0009] In another illustrative, non-limiting embodiment of the invention, a method of forming a tooth ornament base is provided. The method includes: filling a first concavity of a template with a first droplet of a clear, light-curing sealant/resin; covering the template with a clear, non-stick surface to form a flat surface at the upper portion of the first droplet; and light-curing the first droplet to solidify the first droplet and form the tooth ornament base.

[0010] In another illustrative, non-limiting embodiment of the invention, a method of forming a tooth ornament with a mold is provided. The method includes: filling a first concavity of a template with a first droplet of a clear, adhesive, light-curing sealant/resin; covering the template with a clear, non-stick surface to form a flat surface at the upper portion of the first droplet; light-curing the first droplet to solidify the first droplet and form the tooth ornament base having a second concavity; removing the tooth ornament base from the template; placing a second droplet of the clear, adhesive, light-curing sealant/resin into the second concavity; positioning a gemstone into the second droplet and the second concavity; light-curing the second droplet, after the gemstone is positioned; forming a plurality of layers of the clear, adhesive, light-curing sealant/resin on the light-cured first and second droplets and the gemstone; and light-curing each of the plurality of layers, after each of the plurality of layers is formed.

DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS OF THE INVENTION

[0031] The following description of the embodiments discloses specific configurations, features, and operations. However, the embodiments are merely examples of the present invention, and thus, the specific features described below are merely used to more easily describe such embodiments and to provide an overall understanding of the present invention.

[0032] Accordingly, one skilled in the art will readily recognize that the present invention is not limited to the specific embodiments described below. Furthermore, the descriptions of various configurations, features, and operations of the present invention that are readily grasped by one skilled in the art are omitted for the sake of clarity and brevity.

[0033] FIGS. 1-6 show the various stages in the formation of a tooth ornament according to an embodiment of the present invention.

[0034]
FIG. 1 shows a side view of a first clear sealant/resin layer 10, formed from a first droplet of clear sealant/resin and applied to a clean smooth surface 12. In one implementation, the first clear sealant/resin layer 10 is formulated from an adhesive, light-curing, low viscosity, non-filled sealant/resin, which will allow a decorative portion subsequently placed in the first clear sealant/resin layer 10 to be readily visible. An example of such a sealant/resin is FORTIFY™, manufactured by BISCO, Inc. Although light-curing sealant/resin is described herein, self-curing sealant/resin can also be used.

[0035] As is known in the art of dentistry, a non-filled or unfilled sealant/resin is one which is not filled with a colored resin, normally used to match the color of the sealant/resin to the color of the tooth. Ambient light rays will be absorbed and reflected with brilliance due to the unfilled formulation of the sealant. An unfilled resin is very clear and transparent, which is especially advantageous when applying a diamond to the tooth. The transparent nature of the sealant allows for the sparkle of the gems facets to be seen from every outward angle.

[0036] The sealant/resin is used in the dental industry to seal out bacteria and seal fillings and composites, for example. The sealant/resin allows for adhesive bonding. After the sealant has been light-cured, it solidifies and forms a physical bond.

[0037] Although the sealant/resin absorbs and reflects more light rays if it is clear, colored sealant/resins may also be used.

[0038] A variety of materials can be used for the decorative portion, including, for example, one or more of the following materials: light reflective gemstones, precious and non-precious metals, and decals. Examples of light reflective gemstones include, but are not limited to, diamonds, sapphires, rubies, and zirconia. The decals are made of any substance that may be approved for use in the mouth.

[0039] As shown in FIG. 1, the first clear sealant/resin layer 10 is cured with a conventional curing light 11 equipped with a conventional coneshaped curing light enhancer (not shown) to direct the light rays to a specific area for a period of time of approximately twenty seconds. In one implementation, the dimensions of the first clear sealant/resin layer 10 for a gemstone of 0.01-0.02 ct. are about 1 mm thick and about 4 mm wide (as shown in FIG. 1), or for a gemstone of 0.03-0.04 ct. are about 2 mm thick and about 4 mm wide.

[0040]
FIG. 2 shows a side view of the first light-cured clear sealant/resin layer 10 having a triangular cone-shaped concavity 22 drilled into the center by a milling tool (not shown) having a triangular cone-shaped drill bit or bur 21. The purpose of the concavity 22 is to allow for the insertion of a gemstone into the first light-cured clear sealant/resin layer 10.

[0041]
FIG. 3 shows a side view of the first light-cured clear sealant/resin layer 10 with the triangular cone-shaped concavity 22 being filled with a second clear light-curing sealant/resin layer 31, formed from a second droplet of clear sealant/resin, to adhere the gemstone 30 into a centered position of the first light-cured clear sealant/resin layer 10.

[0042]
FIG. 4 shows a side view of the first light-cured clear sealant/resin layer 10 with the gemstone 30 embedded into the triangular cone-shaped concavity 22 being light-cured for approximately twenty seconds to seat the gemstone 30 into and harden the second clear sealant/resin layer 31.

[0043]
FIG. 5 shows a side view of the first and second clear, light-cured sealant/resin layers 10 and 31 with the gemstone 30 embedded into the triangular cone-shaped concavity 22 with a third clear, light-curing sealant/resin layer 50 covering the entire structure. The first, second and third clear light-cured sealant/resin layers 10, 31, and 50 are a clear sealant/resin portion, securing a decorative portion, which is shown in FIG. 5 as a gemstone 30.

[0044] After its addition to the structure, the third clear, light-curing sealant/resin layer 50 is light-cured. The third clear, light-cured sealant/resin layer 50 is added to ensure the security of the gemstone 30, so that the gemstone 30 will not readily dislodge from the first and second layers of clear, light-cured sealant/resin 10 and 31. The third light-cured clear sealant/resin layer 50 will also protect the mouth of an individual having a tooth ornament mounted on a tooth from rough edges of the gemstone 30 or the first and second layers of light-cured clear sealant/resin 10 and 31.

[0045] Instead of only a single third clear, light-curing sealant/resin layer 50 being applied to the structure, a plurality of layers can be applied with each layer being light-cured after being formed on the structure.

[0046] In one implementation, the first, second, and third clear, light-curing sealant/resin layers 10, 31, and 50 are formed of a non-toxic dental sealant resin which is a non-filled, low viscosity sealant/resin having the property of adhesiveness prior to being light-cured.

[0047]
FIG. 6 shows an overview of the gemstone 30 embedded into the clear sealant/resin portion. As shown in FIG. 6, the gemstone 30 is positioned in the center of the clear sealant/resin portion.

[0048] FIGS. 7-10 show the steps for forming a mold, or tooth ornament base, of a tooth ornament according to the present invention.

[0049]
FIG. 7 shows a side view of a template 72 made of, for example, a soft metal, glass, or plastic with a triangular cone-shaped protrusion 73 in the center of the concavity. The template 72 is produced by using a milling tool (not shown) having a drill bit 70 or bur with a width of around 4 mm, which leaves a triangular cone-shaped protrusion 73 in the center of the concavity having approximately a 30° angle. In one implementation, the height of the protrusion 73 for a 0.01-0.02 ct. gemstone is about 1 mm, or about 2 mm for a 0.03-0.04 ct. gemstone.

[0050]
FIG. 8 shows a side view of the concavity containing the protrusion 73 of FIG. 7 filled with clear liquid sealant/resin 80 of a light-curing, low viscosity, non-filled formulation. The sealant/resin 80 is light-cured with a conventional curing light equipped with a conventional cone-shaped curing light enhancer to direct the light rays to a specific area for a period of about twenty seconds.

[0051]
FIG. 9 shows a side view of a template 72 filled to the top of a concavity with clear light-curing sealant/resin 80 and a clear sheet of a nonstick material 90, such as glass or plastic, placed on top of the concavity. This clear sheet acts as a cover that creates the flat surface of sealant/resin that is bonded to the tooth. The sealant/resin 80 is light-cured through the transparent cover for about 30 seconds.

[0052]
FIG. 10 shows a side view of a clear light-cured sealant/resin tooth ornament base 100 having been removed from the template and turned 180°, making it available to accept a gemstone 30. The tooth ornament base 100 of FIG. 10 could then proceed through the steps shown, for example, in FIGS. 3-5 to produce a tooth ornament, as described above.

[0053] FIGS. 11-13 show the steps involved in the formation of a tooth ornament having a decal.

[0054]
FIG. 11 shows a side view of a first layer 110 of clear, adhesive, light-curing sealant/resin formed on a smooth, flat non-stick surface 111. The first layer 110 is at least as large as a decal which is positioned above the first layer 110 in a subsequent operation. After formation of the first layer 110 on the non-stick surface 111, the first layer 110 is light-cured by a curing light 11.

[0055] In FIG. 12, a decal 121 is embedded into a second layer 120 of clear, adhesive, light-curing sealant/resin on a clean smooth surface 111. In one implementation, the second layer 120 of clear, adhesive, light-curing sealant/resin has a low viscosity, non-filled formulation. The width of the second layer 120 is approximately 4 mm. The decal 121, made of any substance that may be approved for use in the mouth, is positioned in the second layer 120 in a central location for the viewing to be appealing to the eye. The second layer 120 containing the decal 121 is light-cured, preferably with a conventional curing light 11 equipped with a conventional cone-shaped curing light enhancer (not shown) used to direct the light rays to a specific area for a period of approximately twenty seconds.

[0056]
FIG. 13 shows a side view of a layer containing a decal being coated with a third layer 130 of clear, adhesive, light-curing sealant/resin to protect the decal 121 from damage from foreign objects striking the tooth or biting particles that could possibly dislodge or damage the decal. The third layer 130 protects the decal from dislodging due to wear, brushing or normal tooth hygiene. The third layer 130 is cured with a conventional curing light 11 and, preferably a cone-shaped curing light tip enhancer (not shown), which directs the light rays to a specific area.

[0057]
FIG. 14 shows a side view of a tooth ornament with a light reflective gemstone 30 formed on a tooth 122. As shown in FIG. 14, the tooth ornament is non-invasively and adhesively attached to the tooth 122 and sealed with a sealant/resin 50. One method of attaching the tooth ornament to the tooth 122 is by etching the tooth 122 and bonding the tooth ornament to the tooth 122 in accordance with conventional dental procedures. Bonding per se is a procedure known to those in the dental profession. The tooth is cleaned and etched, the ornament is placed on the tooth with the dental sealant, the sealant is light cured, and additional layers of sealant are brushed over the ornament to fill in any gaps around the ornament and to create a very smooth surface. Each layer is light cured individually. However, the tooth ornaments of the present invention may be attached to the tooth using other methods.

[0058]
FIG. 15 shows a cross-sectional view of a tool 153 used for holding gemstones during a tooth ornament formation process. The tool 153 has a main body 150 and an ornament holding portion 151 disposed at a top surface of the main body and having a concavity 152 for holding a tooth ornament, such as a gemstone.

[0059]
FIG. 16 shows a top view of the tool 153 with a gemstone 30 positioned in its center.

[0060]
FIG. 17 shows a gemstone 30 on a tool 153 with a first droplet of clear, adhesive, light-curing sealant/resin 180 covering the gemstone 30 and the top of the tool 153. After the first droplet 180 is placed on the gemstone 30 and the top of the tool 153, the first droplet is light-cured.

[0061]
FIG. 18 shows a gemstone 30 and a light-cured first droplet of clear, adhesive light-curing sealant/resin 180 that have been removed from a gemstone holding tool. At the bottom of the gemstone 30 is an area 181 which is not covered by the first droplet of clear, adhesive light-curing sealant/resin 180. The uncovered area 181 is then covered with a second droplet of clear, adhesive light-curing sealant/resin 200, as shown in FIG. 19.

[0062]
FIG. 19 shows a gemstone encased in first and second droplets of clear, adhesive light-curing sealant/resin 180 and 200. The second droplet 200 is placed in the uncovered area 181 after the gemstone 30 and the light-cured first droplet 180 have been removed from the tool 153. Then, the second droplet 200 is light cured to form a complete encasement 201 of the gemstone 30.

[0063] The same type of sealant/resin used in the tooth ornament may be used to bond the tooth ornament to the tooth. Use of the same type of sealant/resin facilitates the bond.

[0064] Although the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that the present invention should not be limited to the described preferred embodiments, but various changes and modifications can be made within the spirit and scope of the present invention as defined by the appended claims.
