Definitions

  • Restorative dentistry is an important market in today's dental industry.
  • tooth repair with temporary and permanent crowns is a common procedure, typically requiring multiple dental appointments.
  • Conventional technologies use liners, adhesives, pastes, two-part powder/liquid systems, preformed metal temporary crowns, and ceramic or porcelain/metal permanent crowns.
  • the problems associated with the conventional technologies are the need for multiple visits to a dentist if a customized dental article is desired. Conversely, if customization is not desired, the dental article used may have a less than desirable fit and/or appearance, e.g., a metallic finish, larger gaps between proximal teeth, significant color variations from natural teeth, etc.
  • Hardenable dental materials have been developed to address some of these issues. Examples of some of these materials are described in, e.g., International Publication No. WO 03/015720 (Karim et al.) and U.S. application Ser. No. 10/219,398 filed Aug. 15, 2002 (Karim et al.), both titled HARDENABLE SELF-SUPPORTING STRUCTURES AND METHODS.
  • “hardenable dental materials” are materials that are capable of being hardened to form dental articles such as crowns, etc.
  • the techniques used to form the hardenable dental materials into usable dental articles may contribute to or detract from the finished appearance of the dental articles.
  • the hardenable dental material may exhibit an undesirable rough appearance due to less than desirable forming techniques and/or packaging.
  • the exact shape of dental articles manufactured of the hardenable materials before final hardening may be adjusted, significant shaping of the materials may not be possible or desirable depending on the properties of the hardenable dental material being used.
  • the dentist may prefer that the materials be provided in a shape that is close to the final desired shape of the dental article—subject to some minor shaping to provide a more customized fit and/or appearance.
  • the time required for the dentist to complete any given dental procedure in which the dental article is used can be reduced. Such forming, however, may exacerbate the problems identified in the preceding paragraphs.
  • the present invention provides methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles.
  • the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner.
  • the mold body may also form the package of the hardenable dental article formed within the mold cavity.
  • the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.
  • the use of a mold liner during manufacturing of hardenable dental articles from hardenable dental materials may provide a number of potential advantages such as assisting with release of the hardenable dental article from the mold cavity; protecting the hardenable dental article from contamination, enhancing the finish of the hardenable dental article by providing a smooth finish on the article during the forming process (if the liner itself is smooth), and enhancing the finish of the dental article after hardening (if the smooth inside surface of the mold liner is retained in intimate contact with the outer surfaces of the hardenable dental article during hardening).
  • a mold liner is used in connection with the manufacturing of a hardenable dental article, it may be preferred that the mold liner be in intimate contact with the outer surfaces of the hardenable dental article after release of the hardenable dental article from the mold cavity. Alternatively, the hardenable dental article may release from the mold liner after or during its removal from the mold cavity.
  • the mold liner may function as an actinic light barrier to retard the passage of actinic radiation that could otherwise prematurely harden the photocurable hardenable dental material.
  • the liner is malleable, the dentist may be able to customize or adjust the shape of the dental crown with the liner in place. Alternatively, the dentist may remove the liner before customizing.
  • the liner may also function as a protective barrier for the outer surfaces of the hardenable dental article. If the liner is maintained in place on the outer surfaces of the hardenable dental article during hardening, it may protect the outer surfaces from, e.g., exposure to oxygen before and during the hardening process. If the liner is to be retained in place during hardening, the liner may be flexible to allow the dentist to customize or shape the hardenable dental article before hardening (if desired).
  • the liner may also function as a portion of the packaging of the hardenable dental articles manufactured of hardenable dental materials in accordance with the present invention.
  • the liner in intimate contact with the outer surfaces of the hardenable dental article
  • the liner may function as a package cover while a package base is attached to contain the hardenable dental article therein (in a manner similar to a “blister pack”).
  • mold cavities formed in reusable mold bodies made of conventional materials such as metals, etc. may be used in connection with manufacturing of hardenable dental articles of the present invention
  • the present invention may also include the use of mold cavities located in sacrificial mold bodies that include, e.g., lines of weakness formed therein, such that after molding or forming of the hardenable dental material into the shape of the selected hardenable dental article, the sacrificial mold body can be separated along the lines of weakness to remove the hardenable dental article from the mold cavity.
  • Other sacrificial mold bodies may be manufactured of materials that can either be stretched or torn to remove the hardenable dental article in the absence of defined lines of weakness.
  • sacrificial mold bodies may be manufactured of materials that can be softened or dissolved by contact with a solvent (such as, e.g., water) that does not significantly adversely affect the hardenable dental article.
  • a solvent such as, e.g., water
  • sacrificial mold bodies could be manufactured of water-soluble materials such that exposure to water (by, e.g., sprays, baths, etc.) softens or dissolves the sacrificial mold body such that the hardenable dental article can be removed—preferably without distorting the shape of the hardenable dental article. All of such mold bodies are described as “sacrificial” because they cannot be reused due to their destruction during the removal process.
  • Removal of a hardenable dental article from a sacrificial mold body may be performed as part of the manufacturing process, with the shaped hardenable dental article being packaged for delivery to a customer after the hardenable dental article has been removed from the sacrificial mold cavity.
  • the sacrificial mold body itself may form a part of the packaging of the hardenable dental article located therein, with removal of the hardenable dental article from the sacrificial mold cavity being performed by, e.g., the dentist or an assistant, at the point of use of the hardenable dental articles.
  • Such sacrificial mold bodies may be used in connection with mold liners as well.
  • the term “dental article” includes, but is not limited to, dental restoratives and dental prostheses, including, e.g., temporary, intermediate, and permanent crowns and bridges, inlays, onlays, implants, dentures, and artificial teeth, etc., as well as orthodontic appliances (e.g., retainers, night guards, etc.), tooth facsimiles or splints, maxillofacial prostheses, and other customized structures.
  • dental restoratives and dental prostheses including, e.g., temporary, intermediate, and permanent crowns and bridges, inlays, onlays, implants, dentures, and artificial teeth, etc., as well as orthodontic appliances (e.g., retainers, night guards, etc.), tooth facsimiles or splints, maxillofacial prostheses, and other customized structures.
  • a “hardenable dental article” may optionally be defined as a self-supporting structure of a hardenable dental material that is dimensionally stable and will maintain its shape (e.g., the preformed shape of a dental crown) without significant deformation at room temperature (i.e., about 20° C. to about 25° C.) for at least two weeks when free-standing (i.e., without any external support).
  • the hardenable dental articles of the present invention are dimensionally stable at room temperature for at least about one month, and, more preferably, for at least about six months.
  • the hardenable dental articles of the present invention are dimensionally stable at temperatures above room temperature, more preferably up to about 40° C., even more preferably up to about 50° C., and even more preferably up to about 60° C. This definition applies in the absence of conditions or materials that would otherwise act to harden the hardenable dental article and in the absence of an external force other than gravity.
  • the present invention provides a method of manufacturing a hardenable dental article by providing a mold cavity in a shape of a hardenable dental article, wherein the mold cavity has an opening; forcing a hardenable dental material into the mold cavity through the opening; providing a liner between the hardenable dental material and the mold cavity; and removing the hardenable dental material and the liner from the mold cavity, wherein the hardenable dental material has the shape of the hardenable dental article.
  • the present invention provides a packaged hardenable dental article including a mass of hardenable dental material in the shape of a hardenable dental article, wherein the hardenable dental article has a base and outer surfaces extending from the base; a package cover conforming to and in intimate contact with the outer surfaces of the hardenable dental article, wherein the package cover includes a polymeric film plastically deformed by the mass of hardenable dental material; and a package base facing the base of the hardenable dental article; wherein the package cover and the package base are attached together about a periphery of the base of the hardenable dental article such that the hardenable dental article is contained within the package base and the package cover.
