Abstract

A device for holding small objects used in dentistry is disclosed. The device is suitable for use to hold a dental veneer, inlay, onlay, or crown before and during placement. In some implementations, the device includes a handle and at least one removable suction tip attached thereto that can adhere to small objects. In other implementations, the device includes a handle and at least one removable restoration carrier tip attached thereto. The handle may be an independent component that is configured to have one or two removable suction tips or restoration carrier tips attached thereto or may alternatively be part of a curing light. The device is composed of a clear or translucent soft material with a Shore A durometer hardness of between about 30 and about 50. The device allows a user to polymerize a light curable adhesive through the body of the removable tip or restoration carrier tip.

Abstract

The present disclosure describes a device used to determine the optimal post-curing exposure time for 3D printed products and methods of using the same. The disclosed device is a self-contained multi-chamber radiometer for continuous monitoring of electromagnetic radiation transmitted through 3D printed objects during a post-curing process. The device includes multiple detector ports, including a control port and one or more sample ports. The detector ports may preferably be photocells configured to generate a voltage proportional to the intensity of the incident electromagnetic radiation at specific wavelength(s). The transmittance is directly correlated with the voltage and may be measured using the determined voltages. The disclosed device may further comprise a microprocessor, a memory module for storage of data obtained by the sensors, and one or more communication modules configured to enable wireless communication with a data storage device such as a computer.

Abstract

A combination heater assembly made of positive temperature coefficient (PTC) material such as barium titanate ceramic that may be self-regulating. A dental compule may be generally cylindrical, or another shape, and may hold a dental (e.g. composite) material. The compule may be made from conventional plastic or thermally conductive plastic. A compule may also be made from electrically conductive plastic that is self-heating when an electric current is passed through the compule. A compule may be generally cylindrical and include an electrically conductive polymer that may exhibit PTC characteristics while generating heat when electric current is applied to the polymer through two flat contact areas each disposed along one portion of the generally cylindrical compule, an orifice or opening positioned at one end of the compule, an inner chamber; and extrudable dental material held within the inner chamber.
