摘要:
A dental appliance comprising a veneer, bridge, or crown with an integrated brace together formed as a single piece of material. The braces, crowns, veneers, and bridges may be printed with 3-dimesional (3D) software and SLA milling. Embodiments of the present invention provide the printed veneer, crown or bridge with an orthodontic portion (“brace” or “bracket”) that is all one piece. This can be used to move teeth orthodontically and provide a degree of esthetics. The appliance may include identification marks, which may guide placement of the appliance in a patient's mouth. The brace and identification marks can be removed, leaving the veneer, crown, or bridge behind.

A dental restorative device is shown as comprising a first cured or hardened layer in the form of an occlusal surface of the tooth being restored and a second uncured dental composite layer joined to the first layer enabling a dental professional to perform direct dental restoration procedures with results replicating indirect direct dental restoration procedures. A system comprising the multi-layered dental restorative device and packaging provides for sufficient support and protection of the uncured second layer and facilitates positioning and finishing of the dental restorative device by cooling the uncured portions to a rigid state while in the packaging, positioning the dental restorative device, and modifying the second layer to fit, curing the second layer and permanently placing the fully cured and hardened dental crown on the tooth being restored.

Provided is a method for producing a temporary prosthesis that can be easily performed at a dental clinic and that at the same time enables fabrication of a temporary prosthesis that is less susceptible to wear and damage. The present invention is achieved by fabricating an occlusal surface with a dental composite resin that has higher strength compared to a conventional room temperature polymerization resin. The method includes fabricating a prosthesis model, using an impression material to take an impression of a prepared tooth model having the prosthesis model mounted thereon, applying a layer of dental composite resin material to a portion that is to become a crown within the impression that has been removed from the prepared tooth model and polymerizing the composite resin material, putting a powder-liquid mixture of a powder-liquid type room temperature polymerization resin into the impression, refitting the prepared tooth model to the impression, and curing the room temperature polymerization resin.

Described herein is a method of treating the hair. The method includes applying to the hair a hair treatment composition including one or more fluorescent compounds and rinsing the hair with water. The one or more fluorescent compounds each include a fluorophore, one or two permanent cations, and one to four incipient cations. The incipient cations are pendant to the core structure and are neutral. The one or more fluorescent compounds enter the hair shaft after the hair treatment composition is applied to the hair. The hair treatment composition has a pH of from about 7 to about 11. The pH of the hair after rinsing is from about 3.5 to about 6. The rinsing of the hair causes one or more of the one to four incipient cations to change from neutral to positively charged inside of the hair shaft.

A process for making a dental restoration includes forming a dental restoration base, selecting a decal representing a natural oral cavity characteristic, and attaching the selected decal to the base. Thereafter, the decal and the dental restoration base are conditioned to create a finished dental restoration having desired oral cavity color and characteristics such as teeth, enamel, dentin, crazing lines, stains, veins, blood vessels, bony coloration, hyper-calcification, mucosal tissue or gum tissue. In an alternative embodiment, the process may include placing a sealant over the decal and at least a portion of the dental restoration base. Additionally, a secondary decal may be attached over the sealant, followed by glazing the secondary decal.
摘要:
The invention relates to glass-ceramics based on the lithium disilicate system which can be mechanically machined easily in an intermediate step of crystallization and, after complete crystallization, represent a very strong, highly-translucent and chemically-stable glass-ceramic. Likewise, the invention relates to a method for the production of these glass-ceramics. The glass-ceramics according to the invention are used as dental material.

In one aspect the present disclosure relates to a process for producing a dental article comprising at least two parts, Part A (e.g. coping) and Part B (e.g. veneer), Part A and Part B each having a 3-dim. structure and an outer and an inner surface, the outer surface of Part A having a shape which essentially corresponds to the shape of the inner surface of Part B, Part B comprising a material with a porous section and being produced with the aid of a rapid-prototyping technique, the process comprising a first heating step, wherein Part A is serving as support structure for Part B during said heating step.
摘要:
A method and apparatus are disclosed enabling an orthodontist or a user to create an unified three dimensional virtual craniofacial and dentition model of actual, as-is static and functional anatomy of a patient, from data representing facial bone structure; upper jaw and lower jaw; facial soft tissue; teeth including crowns and roots; information of the position of the roots relative to each other; and relative to the facial bone structure of the patient; obtained by scanning as-is anatomy of craniofacial and dentition structures of the patient with a volume scanning device; and data representing three dimensional virtual models of the patient's upper and lower gingiva, obtained from scanning the patient's upper and lower gingiva either (a) with a volume scanning device, or (a) with a surface scanning device. Such craniofacial and dentition models of the patient can be used in optimally planning treatment of a patient.
摘要:
A method and process for at least partially forming a medical device. The present invention is generally directed to a medical device that is at least partially made of a novel alloy having improved properties as compared to past medical devices. The novel alloy used to at least partially form the medical device improves one or more properties (e.g., strength, durability, hardness, biostability, bendability, coefficient of friction, radial strength, flexibility, tensile strength, tensile elongation, longitudinal lengthening, stress-strain properties, improved recoil properties, radiopacity, heat sensitivity, biocompatibility, improved fatigue life, crack resistance, crack propagation resistance, etc.) of such medical device.
