Definitions

  • zirconia is a popular material from which dental replacements are made.
  • zirconia creates a very hard surface, which is not easily colored.
  • Zirconia also requires firing at temperatures over 900°C. At that temperature, the pigments traditionally used to color dental ceramics disappear and lose color.
  • no stains or other colorants will adhere or bond to Zirconia ceramics.
  • Zirconia is a very strong material and the dental sciences are quickly adopting zirconia ceramics for use in dental restorations.
  • a drawback to the use of zirconia is the stark white color of the material.
  • Most individuals prefer dental restorations which have the appearance and color of a natural tooth. Specifically, individuals wish to have dental restorations that blend in naturally with the remaining teeth.
  • a system, method and composition for coloring dental ceramics The system, method, and composition resulting in natural color matching without drying time between color layers. The system, method and composition also resulting in good color preparation on restorations of about O.OOlmm-1.000mm thickness.

  • FIG. 2 illustrates the thickness of restorations.
  • FIG. 3 illustrates the success of the thin restoration in masking underlying color defects.
  • FIG. 4 illustrates the absorption of the disclosed composition.
  • FIG. 5 illustrates the comparative protective properties of the disclosed system over the currently employed systems.
  • CAD/CAM technology may be used in dentistry to help dentists and dental technicians fabricate precise shapes and sizes for dental restorations, including, for example, inlays, onlays, crowns, and bridges.
  • Dentists may use CAD/CAM and other related technologies to provide their patients with durable, well-fitted single and multiple tooth restorations.
  • Dentists and dental technicians may use CAD/CAM and other technologies to design the anatomical features, size, and shape of a tooth restoration, for example but not limited to, on a computer.
  • CAD/CAM the machine fabricates the restoration through a milling chamber that crafts the tooth-like ceramic material into a precise replica of the drawing.
  • ceramic may be used for in-lays, on-lays, crowns, veneers, as well as full restorations, among others.
  • full ceramic restorations are particularly desirable because their color and translucency mimic natural tooth enamel.
  • a method, system, and composition that may be used to impart a natural color to dental restorations.
  • the method, system, and device may eliminate the need to use mask layers of opaque and body porcelains.
  • the method, system, and solution may be capable of preparation on the edge of a knife and may eliminate the need to shoulder prep for color.
  • a natural tooth when being prepared for restoration, is reduced in size so it can accept a crown.
  • the method, system, and composition may require short or no drying time and multiple applications of different shades may be possible.
  • Application of the method, system, and composition may result in a three dimensional appearance of the dental restoration that more closely resembles an individuals natural teeth than the currently available coloring systems.
  • this crown comprised layers: a metal cap or understructure for strength and support; a dentin-colored opaque layer to mask the metal; a body porcelain layer; an enamel porcelain layer; and a glaze finish.
  • a natural tooth is darker and more opaque in its gingival region; lighter and more translucent at its incisal edge.
  • the process of dental restoration utilizes both internal and external coloring techniques.
  • pre-sintered zirconia is porous and can absorb colorant as a function of time and intensity, shading can be achieved both internally and at the surface.
  • an enamel-colored zirconia blank the means of producing which can include a doping method that uniformly imparts color to pre-pressed zirconia powder. It is unique in that it moves away from the dark or opaquish appearance of currently available blanks to the color of dental enamel, which is the most difficult to achieve aspect of tooth color reproduction. Theoretically and practically, one can more easily opacify than clarify zirconia with the addition of color; and it is easier to darken than to lighten zirconia by the application of pigment. Producing the enamel coloration of a crown's 1/3 incisal portion is much more technique-sensitive and critical than achieving the orangish ivory of the gingival portion. By starting with an enamel colored blank, the hardest part of the crown coloring process is eliminated, and a more consistent, predictable result can be achieved.
  • a finished crown must contain both the light blue grey coloring of the 1/3 incisal portion as well as the darker orangish ivory of the gingival portion. Results are more natural and achievable when orange colorant is applied to an enamel colored blank than when an attempt is made to cover an orange substrate with translucent incisal colorant. Orange can always be added, but it can seldom be subtracted, attempting to cover it usually results in an even darker shade of lower value. And an incisal translucent effect is more realistic when it appears to come from within rather than having been applied to the surface.
  • Crowns tooth-shaped zirconia with no porcelain overlay provides a second option for zirconia restoration.
  • the systems disclosed herein may provide a system of coloring ceramics without the use of harmful acids that are present in currently known systems.
  • the advantage of this is the reduction of acid also reduces damages to equipment and tools used in ceramic arts.

  • a second system relates to post-sintering coloring of dental ceramics.
  • a method of minimally invasive dental restoration is also disclosed.
  • a third system relates to imparting a fluorescent finish to ceramics, for example but not limited to, zirconia and porcelain ceramics.
  • Dental restorations are commonly prepared with a substructure of a metal or ceramic material upon which substructure layers of porcelain are applied.
  • ceramic or metal alloy substructures may be first covered by an opaque layer, followed by an opacious dentin layer, a dentin layer and finally an incisal porcelain layer.
  • Aesthetics of the dental restoration is of great importance. Patients desire a natural appearance of the prosthesis. In order to achieve a natural appearance of the prosthesis, the dental technician must carefully match and color the framework or facing ceramics. A natural appearance relies not only on color, but on translucence. Currently, most coloring systems require several procedures and layers, which are finally fired (sintered) in an oven. The current coloring systems are therefore time consuming and expensive.
  • the current coloring systems may not provide a satisfactory level of natural appearance.
  • dental implants created under current coloring systems often have a shadow from the cast metal.
  • Increased numbers of ceramic layers may be used to mask the shadow from the cast metal, however, to accommodate the increased number of layers, the dental professional must remove an equivalent amount of tooth material.
  • the removal of tooth material for example, removal of enamel that compromises the integrity of the dentine layer, has lead to the observation that over 22% of restored teeth decay after 5 years.
  • the disclosed system is particularly applicable to zirconia restorations, due to the coloring difficulties inherent to zirconia - however, the disclosed system may be used with porcelain or other traditional ceramics with similar results. While we primarily focus our disclosure on use with zirconia, we do not limit the scope of our claims to the use of our disclosed systems and methods to only zirconia ceramics.

  • the known colored zirconia blanks simulate natural dentin rather than simulating the translucence of the outer layers, for example, the enamel of the tooth.
  • Dentin is the second layer of a natural tooth, which may be softer, more porous, and darker than the hard, dense, semi-translucent outer layer of enamel which protects it.
