Prior approaches to providing oral appliances with appropriate ornamental aspects can be less than ideal in at least some respects. Objects placed in the mouth should be biocompatible and the mouth can present a challenging environment for materials in at least some respects. At least some of the prior approaches to inkjet printing can be less than ideally suited for oral applications.
Ultraviolet light cured (UV) inkjet printing is a digital printing technology that is gaining popularity in recent years due to its combination of high speed, reliability, high image quality and exceptional image durability. UV inkjet printing can be useful for decorating thin plastic films since it does not require special coatings or layers, operates at low temperatures and prints without any mechanical impact to the substrate.
Typical UV inkjet inks have very low viscosity to be jetted through the small nozzles of the printhead. In order to achieve this, UV inkjet inks may contain a low molecular weight reactive monomer and low molecular weight photoinitiator. After jetting through the printhead the monomer is polymerized and hardens on the print substrate when exposed to UV light. In general, the polymerization reaction does not convert all the monomer and photoinitiator, leaving the unreacted portion to easily migrate to the surrounding environment. In at least some instances, the composition of these monomers and photoinitiators can be regarded as unsafe for human consumption and their use may be limited to applications such as food packaging or medical device decoration. UV inkjet inks referred to as low migration inks are available as an alternative and are designed to limit potential migration of residual ink compounds. They typically use a combination of highly reactive yet low viscosity monomers and photoinitiators that are diffusion hindered. This combination can provide a high degree of polymerization with decreased levels of extractable compounds and can be used for food-safe packaging decoration.
At least some of the prior approaches can be less than ideally suited for use with oral appliances. Decorating irregularly shaped articles such as dental appliances can rely on a thin, flexible and conformable film as the image carrier. However, handling such films during printing and subsequent converting steps can limit the type of film that can be used, and at least some of the prior films are less than ideally suited for use with oral appliances.
One potential challenge associated with UV inks is that oxygen inhibition can result in less than ideal curing. Due to the relatively low viscosity of UV inks, they can be especially prone to oxygen inhibition, which may slow the cure response of the ink. To overcome this, one prior approach has been for an inkjet ink to contain higher levels of photoinitiators to enable a sufficiently cured ink film to be produced. However, such high concentrations of photoinitiators could potentially decrease the food safe nature of the ink and the final properties of the cured ink.
In light of the above, there is a need for improved methods and apparatus for use with oral appliances.
In some embodiments, the ornamental indicia carrier comprises an ultraviolet light (“UV”) cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier can be configured for use with a mouth for an extended period of time and can be used in conjunction with a dental appliance.
All patents, applications, and publications referred to and identified herein are hereby incorporated by reference in their entirety, and shall be considered fully incorporated by reference even though referred to elsewhere in the application.
A better understanding of the features, advantages and principles of the present disclosure will be obtained by reference to the following detailed description that sets forth illustrative embodiments, and the accompanying drawings of which:
The following detailed description provides a better understanding of the features and advantages of the inventions described in the present disclosure in accordance with the embodiments disclosed herein. Although the detailed description includes many specific embodiments, these are provided by way of example only and should not be construed as limiting the scope of the inventions disclosed herein.
The presently disclosed surface printed ornamental indicia carriers can be used with many objects such as oral appliances. Examples of suitable oral appliances include, sports guards, mouthpieces, aligners, tooth positioners, retainers, apnea devices, jaw repositioning devices, and palatal expanders. Although reference is made to oral appliances, the presently disclosed ornamental carriers can be used with many objects in addition to oral appliances.
In some embodiments, a dental appliance can include a multi-layer material having a first layer with a first elastic modulus and a second layer with a second elastic modulus less than the first elastic modulus. A dental appliance can also include various combinations of materials, including alternating configurations of hard and soft material (e.g., hard, soft, hard material combinations; soft, hard, soft material combinations; etc.). Suitable polymeric materials for a first polymer layer can include a polyester, a co-polyester, a polycarbonate, a thermoplastic polyurethane, a polypropylene, a polyethylene, a polypropylene and polyethylene copolymer, an acrylic, a cyclic block copolymer, a polyetheretherketone, a polyamide, a polyethylene terephthalate, a polybutylene terephthalate, a polyetherimide, a polyethersulfone, a polytrimethylene terephthalate or a combination thereof (e.g., a blend of at least two of the listed hard polymeric materials). In some embodiments, a first polymer layer of a dental appliance can include polymeric materials, such as a polycarbonate, a co-polyester, a polyester, and a thermoplastic polyurethane. In some embodiments, a first layer can be composed of multiple layers, e.g., two or three polymer layers co-extruded to form one layer.
A first polymer layer can have a variety of physical properties that can, e.g., improve treatment options for a practitioner. For example, physical properties such as tensile strength, elongation at yield, elongation at break, tensile modulus, flexural modulus, stress relaxation over time, and light transmission can each be specifically tailored for a particular application. In some embodiments, a first polymer layer of the appliances can have a physical property of at least one of a tensile strength at yield of between about 4000 pounds per square inch (psi) and 6500 psi, an elongation at yield of greater than about 4%, an elongation at break of greater than about 70%, a tensile modulus of greater than about 150,000 psi, a flexural modulus greater than about 150,000 psi, a stress relaxation at 24 hours testing in a wet environment (e.g., between about 90%-100% relative humidity) is greater than 10%, and a light transmission between 400 nm and 800 nm of greater than about 75%.
Suitable polymeric materials for a second polymer layer can include a styrenic block copolymer (SBC), a silicone rubber, an elastomeric alloy, a thermoplastic elastomer (TPE), a thermoplastic vulcanizate (TPV) elastomer, a polyurethane elastomer, a block copolymer elastomer, a polyolefin blend elastomer, a thermoplastic co-polyester elastomer, a thermoplastic polyamide elastomer, or a combination thereof (e.g., a blend of at least two of the listed polymeric materials). The second polymer layers can be the same material or a different material. In certain embodiments, different layers in a dental appliance are the same polymeric material.
A second polymer can have a variety of physical properties. For example, physical properties such as hardness, ultimate tensile strength, elongation at break, tensile modulus, compression set, flexural modulus, and light transmission can each be specifically tailored for a particular application. In some embodiments, a second polymer layer can independently have a physical property of at least one of a hardness of about 60 A to about 85 D, an ultimate tensile strength of greater than about 5000 psi, an elongation at break of greater than about 200%, a compression set at about 70° C. of greater than 40% after 24 hours, a flexural modulus of greater than about 35,000 psi, and a light transmission between 400 nm and 800 nm of greater than about 75%.
As described herein, the layers of the appliances can include a first polymer layer disposed between two second polymer layers. In one embodiment, the multilayer appliances can include a first polymer layer of one type of material (e.g., a co-polyester), and two second polymer layers of other types of material that can be the same or different (e.g., two second polymer layers of thermoplastic polyurethane elastomer). In some embodiments, the multilayer appliances can also include a first polymer layer of at least two layers of polymer material. For example, the first polymer layer can include several polymer layers laminated together to form the first polymer layer. The laminated first polymer layer can include at least two layers of any combination of the following polymer materials: a polyester, a co-polyester, a polycarbonate, a thermoplastic polyurethane, a polypropylene, a polyethylene, a polypropylene and polyethylene copolymer, an acrylic, a cyclic block copolymer, a polyetheretherketone, a polyamide, a polyethylene terephthalate, a polybutylene terephthalate, a polyetherimide, a polyethersulfone, and a polytrimethylene terephthalate. Similarly, in some embodiments, the multilayer appliances can include a second polymer layer of at least two layers of polymer material. In some embodiments, the layers of an appliance can include a second polymer layer disposed between two first polymer layers. Any of the foregoing materials can be used for this combination.
The one or more ornamental indicia carriers 110 can be placed at any suitable location of the oral appliance 100. The ornamental indicia carrier 110 comprises suitable materials for use with an oral appliance 100. Although reference is made to UV curable inks, other print techniques can be used such as water based inks or solvent based inks.
In some embodiments, the ornamental carrier 110 comprises a polyolefin film to provide a combination of clarity, flexibility and robustness suitable for use with appliances. For example, oriented polyolefin films such as biaxially oriented polypropylene (BOPP) films can be used as thin gauge, high clarity and conformable films for decorating objects such as oral appliances. As a thin film, BOPP films have an appropriate stiffness in the machine direction during printing to decrease stretching of the film when moving through rollers of a printing press. These films can also have coextruded skin layers that can be corona treated to improve print adhesion, in some instances without requiring an additional top-coat layer.
In accordance with embodiments of the present disclosure, a non-contact printing process such as inkjet printing can be used with thin BOPP films with thickness in the range of 35 microns to 60 microns that can be handled through the process without substantial stretching or web breaking.
The inks can be configured to match the BOPP film, printhead, UV curing system and other elements of the printing system and process. The process of designing a finely tuned ink system can involve refining the printed image quality with good physical properties such as adhesion, flexibility and scratch resistance. Based on the teachings disclosed herein, one or ordinary skill in the can design an ink system to deliver a high-quality indelible marking of the indicia with appropriate durability.
In some embodiments, incomplete curing of the ink can be addressed by applying first a UV ink followed by an overprint varnish (OPV) and curing. This approach enables UV inks with lower levels of photoinitiator to be used. This can be achieved by applying an OPV layer (preferably UV curable) onto a previously partially cured ink layer, and then exposing the combined ink-OPV bi-layer to further UV irradiation. The OPV and ink can be formulated in such a way that applying them on top of each other allows the partially cured ink to become fully cured when protected from atmospheric oxygen by the overlaying OPV. In some embodiments, the ink of the OPV bilayer is exposed to a second dose of UV-irradiation that results in further radical generation throughout the underlying ink layer resulting in further conversion of unreacted monomer. In some embodiments, an in-line process for the preparation of decorative indicia by the ink-OPV combination encompasses the deposition of the ink component first, with subsequent preliminary (or ‘pinning’) UV-cure, followed by the deposition of the OPV component, with subsequent cure of the ink-OPV layer with a suitable dose of UV-light. In some embodiments, the OPV component also provides functionality that may not be readily achievable by the inks alone. For example, the OPV can be modified to provide the required slip, abrasion resistance, chemical resistance required of the printed ink-OPV combination.
In some embodiments, an alternate way to achieve indelible marking of indicia is by printing a mirror or reverse image that is visible through the clear flexible film. This approach may decrease the need for an OPV to protect the surface printed inks. Such reverse printed indicia can be produced by printing on the thin BOPP film as described herein, applying the adhesive to the printed side of the film over the ink and laminating the combination to a pre-silicone-coated polymeric film or paper liner. Reverse printed indicia can be further combined with white ink printed over the reverse image to create an opaque background which enhances the color density and graphic quality of the printed indicia. In some embodiments, the opaque background color may not be white. In some embodiment, the opaque background may have a color selected to match the color and a patient's teeth. In some embodiment, the opaque background may have a color selected within a range of human tooth colors.
Thin flexible BOPP film printed with UV inkjet inks in either surface printed or reverse printed format can be subsequently combined with a pressure sensitive adhesive that adheres well to a variety of materials typically used in medical and dental devices. In some embodiments, the pressure sensitive adhesive is a high tack synthetic rubber-based transfer adhesive designed for medical device applications and is approved for use on skin.
In some embodiments, an ornamental indicia carrier can remain durably adhered to a dental appliance “Durably adhered,” as used herein, may refer to an adherence property of a material (e.g., an ornamental indicia carrier). Durably adhered, as used herein, may refer to a material remaining adhered to a surface, even under humid and/or wet conditions, and being able to withstand abrasive, rubbing, and/or other mechanical forces. Whether a material is durably adhered to another can be assessed by any number of tests, including abrasiveness tests and/or liquid immersion tests (e.g., water immersion tests). In some embodiments, a process that results in an ornamental indicia carrier remaining adhered at a desired level, such as greater than 75%, greater than 90%, greater than 95%, greater than 99%, or 100%, after a 24 hour water immersion test, including for water at a temperature corresponding to the oral cavity, may be characterized as durably adhered, including for a standard adhesive test such as by a tape test.
“High humidity” or “wet environment,” as used herein may refer to environments having a substantial liquid aspect. For example, the oral cavity of a living animal, including a human, may be considered herein to be a high humidity and a wet environment. Immersion, total or partial, in a liquid may also be considered a wet environment.
Unless explicitly defined otherwise, “substantial,” as used herein, may refer to a value that is within at least 20%, within at least 10%, or within at least 5% of a desired value, or that is equal to a value.
“Soak time,” as used herein, may refer to the time elapsed between ink application/contact with the substrate and the process of curing. A precise soak time may depend on process conditions and material variables, including temperature, ink composition, material composition and/or shape (e.g., adhesive composition and/or shape), for example. Similarly, an application of interest in which an ornamental indicia carrier will be used may influence soak time. For example, applications requiring stronger adhesion may have a longer soak time than applications where a lesser adhesive force is suitable.
“Operably coupled,” as used herein, may refer to a configuration between two or more components such that the functionality of each component is maintained. Operably coupled may include configurations in which components are directly connected to each other as well as configurations where components are indirectly connected to one.
“Polymer,” as used herein, may refer to a molecule composed of repeating structural units connected by covalent chemical bonds often characterized by a substantial number of repeating units (e.g., equal to or greater than 3 repeating units, optionally, in some embodiments equal to or greater than 10 repeating units, in some embodiments greater or equal to 30 repeating units) and a high molecular weight (e.g. greater than or equal to 10,000 Da, in some embodiments greater than or equal to 50,000 Da or greater than or equal to 100,000 Da). Polymers are commonly the polymerization product of one or more monomer precursors. The term polymer includes homopolymers, or polymers consisting essentially of a single repeating monomer subunit. The term polymer also includes copolymers which are formed when two or more different types of monomers are linked in the same polymer. Useful polymers include organic polymers or inorganic polymers that may be in amorphous, semi-amorphous, crystalline or semi-crystalline states.
“Polymer network,” as used herein, may refer to a polymer composition comprising a plurality of polymer chains wherein a large portion (e.g., >80%) and optionally all the polymer chains are interconnected, for example via covalent crosslinking, to form a single polymer composition. In an embodiment, there is provided a radiopaque polymer in the form of a crosslinked network in which at least some of the crosslinks of the network structure are formed by covalent bonds.
“Monomer,” as used herein, may refer to a reagent which can undergo polymerization under one or more specified conditions. A monomer reagent may comprise at least one monomer molecule, where a monomer molecule is a molecule which can undergo polymerization, thereby contributing constitutional units to the structure of a macromolecule or oligomer. In an embodiment, a monomer reagent may be represented by an average or dominant chemical structure and comprise monomer molecules having that chemical structure but may also contain components with other chemical structures. For example, a monomer reagent may comprise impurities having chemical structures other than the average or dominant structure of the reagent. An oligomer or oligomeric reagent is also a reagent which can undergo polymerization under appropriate conditions. An oligomeric reagent comprises an oligomer molecule, the oligomer molecule comprising a small plurality of units derived from molecules of lower relative molecular mass. In an embodiment, certain hyperbranched crosslinking reagents suitable for use with the invention may be regarded as oligomeric reagents.
The term “biocompatible” refers to a material that does not cause immune rejection or detrimental effect, which is referred to herein as an adverse immune response, when disposed within an in vivo biological environment. For example, In embodiments, a biological marker indicative of an immune response changes less than 10%, or less than 20%, or less than 25%, or less than 40%, or less than 50% from a reference value. when a human or animal is exposed to or comes into contact with the biocompatible material. Alternatively, the immune response can be determined histologically, in which the localized immune response is assessed by means of visual assessment markers, which include immune cells or markers that are involved in the path of the immune response, in and adjacent to the material. In one aspect, a biocompatible material or device does not observably change the immune response as determined histologically. In some embodiments, the present invention provides biocompatible devices configured for long-term use, such as on the order of weeks to months, without invoking an adverse immune response. Biological effects can be initially assessed by measuring cytotoxicity, sensitization, irritation and intracutaneous reactivity, acute systemic toxicity, pyrogenicity, subacute/subchronic toxicity and/or implantation. Biological tests for supplemental evaluation include tests for chronic toxicity.
