Continuous adjustment appliances are provided that can store a large number of geometries that can be successively accessed throughout orthodontic treatment, with each geometry can correspond to an arrangement of the patient's teeth. An appliance according to the present disclosure can be stimulated to transition among the myriad geometries, which can include changes to the overall shape of the appliance as well as the position and geometry of the cavities corresponding to a patient's teeth. Methods of creating the continuous adjustment appliances and methods of treatment using the continuous adjustment appliances are also revealed.

A three-dimensional printing system includes a resin vessel, a support tray, a motorized carriage, a light engine, and a controller. The resin vessel has a lower side with a transparent sheet which provides a lower bound for photocurable resin contained within the vessel. The support tray has a lower face for supporting an object being fabricated. The motorized carriage is for supporting and vertically positioning the support tray. The light engine is for projecting radiation up through the transparent sheet to a build plane. The controller operates the motorized carriage and the light engine to fabricate the object. The object includes a vertical arrangement of dental arches suspended from the lower face and a plurality couplings that connect pairs of the dental arches.

A dental device system includes a dental device configured to transmit data via a narrowband network to a computing device that outputs a notification indicative of a device management operation. The dental device system includes a computing device and a dental device. The dental device includes a sensor configured to generate a signal indicative of a condition of the dental device and communication circuitry configured to receive the signal from the sensor and transmit data indicative of a health of the dental device via a narrowband network to the computing device. The computing device is configured to determine, based on the data indicative of the health of the dental device, the health of the dental device; determine, based on the health, a device management operation; and output a notification indicative of the device management operation.

Disclosed is an anatomical drape, such as a dental drape, for covering a treatment area of an anatomical part. The drape includes an elastomeric material capable of conforming to the contours of the anatomical part. The drape preferably includes a curing agent. Activation of the curing agent, for example by a light source, causes selective hardening of the stretched material to at least partially set the drape in a configuration conforming to the anatomical part. The semi-rigid set drape preferably is liquid impermeable but gas permeable. A method of manufacturing the drape is also disclosed.

The present disclosure describes systems and methods for radiometry in dental applications. The disclosed systems include a radiometer, a dental curing light, a composite material reader module, and a restoration data storage device, where one or more of the radiometer, dental curing light, composite material reader module, and restoration data storage device include one or more communication modules that enable wireless communication between one or more of the radiometer, curing light, composite material reader module, and restoration data storage device. In some preferred embodiments, the radiometer includes at least one communication module and the curing light includes at least one communication module. In such embodiments, the communication modules may be used to transmit information between the radiometer and the curing light, and between one or more of the radiometer and curing light and one or more of the composite material reader module and restoration data storage device.

An autoclavable medical device is provided that includes a metal housing having an electrical conductor embedded in an inorganic fixing material. The conductor and fixing material define an electrical feedthrough that extends from an interior of the housing through at least a portion of the fixing material. The electrical feedthrough forms part of a sensor of an actuation means for the autoclavable medical device.

The invention relates to a polymerization and post-tempering device (10) for tempering, in particular post-tempering, dental restoration parts (54) made of polymerizable plastics. At least one light source (38) which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door (14) to the light chamber are provided. The door (14) comprises a window (20) with a window pane (22) which consists of at least two layers (56, 58) whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.

Dental devices and systems and methods for making dental devices are described herein. In some embodiments, denture base material may be adapted to fit a model of a patient's mouth, and a pre-set arch of denture teeth may be adjusted the model. The pre-set arch may be impressed into the denture base material to create a channel. In some embodiments, the cure may be a partial cure and/or a releasing agent may be used such that the pre-set arch may be removed, if needed for further adjustments, after assessing the fit of the denture device. If the fit is correct, another cure may be performed to finish the denture device. If the fit is incorrect, a new bite registration and/or adjustments to the denture base material and/or pre-set arch of denture teeth may be made.

Methods produce a three-dimensional dental block of material from a dental, polymerizable material. The methods include at least: transferring the polymerizable dental material into a radiolucent three-dimensional casting or press mold; irradiating the polymerizable dental material substantially from all sides with light in the UV/Ms spectral region forming polymerized outer surfaces of the dental material in the form of a solid outer shell of the dental material, wherein the shell is present in the defined three-dimensional geometry of the material whilst the inner region of the material is not polymerized or partially polymerized; heating the material with solid shell being present in defined three-dimensional geometry, to 60 C. to 150 C. for at least 90 minutes; and obtaining a dental, polymerized block of material having defined three-dimensional geometry.

A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode (LED) portion of the curing light. The device body is one-piece body formed from a continuous seamless piece of thermally conductive material extending between a proximal end and a distal end. The one-piece body includes a gripping handle portion extending to the proximal end and a light-emitting head portion extending to the distal end. The one-piece thermally conductive body acts as a heat sink to efficiently conduct heat away from the LED dies during use. The one-piece body eliminates problems of multi-segmented curing lights that include one or more joints between adjacent segments. Eliminating joints increases thermal conductivity of the body, eliminates crevices where microbes can grow, and eliminates the risk of accidental separation if the curing light is dropped.
