A dental tool configured for being held by a dental apparatus, the dental tool having at least one material-removing edge in a front portion thereof and a gripping portion in a rear portion thereof, wherein the dental tool comprises a transponder. A system may be provided for receiving data from the transponder and displaying an indication thereof to a user and/or process the data to assist a user in dental activities.

A connecting element, a base unit and a cleaning head for use in an oral care appliance are disclosed. The connecting element is configured to engage operatively with the cleaning head and the base unit to form a first connection and a second connection respectively.

Described herein are systems and methods for marking models for dental aligner fabrication. A method for producing a physical model of teeth including a three-dimensional marking includes receiving a first digital model of teeth in an alignment position and selecting a location for marking a physical model of the teeth in the alignment position with a three-dimensional marking, the physical model to be fabricated based on the first digital model. The method also includes generating a second digital model of the teeth in the alignment position based on the first digital model, the second digital model representing the physical model and including the three-dimensional marking at the marking location, and using a three-dimensional fabrication method to fabricate the physical model including the three-dimensional marking from the second digital model.

The invention provides a unitary cordless dental drive apparatus in a first embodiment having a handpiece with a cantilever arm 18 extending outward and positioned to allow a dental nose cone 26 to be connected. An activating switch 20 is located at the free end of the cantilever arm 18 in a position that is convenient for manipulation by a user. In a second embodiment, a contactor 22 is mounted below the cantilever arm 18 to contact the nose cone 26 when pressed. In a third embodiment, a standard dental office foot pedal 90 is connected to a wireless transmitter 80 for sending a signal to a receiver 92 located within the handpiece 70 for activating the handpiece 70.

The present disclosure provides an oral data collection device comprising a mouthguard and at least two sensors, a medical analytics system comprising the device, and methods of using the device and system to provide a personalized treatment protocol, stage a health condition, measure a response to therapy, phenotype for selection to participate in drug trials, measure stability of an anatomical structure, or predict a rate of change of a health condition in a subject in need thereof.

A microchip denture implant kit, system, and method. The kit, system, and method include a microchip having a transmitter for transmitting a wireless signal containing information relating to a user or a dental prosthetic, and an external reader scanner in communication with the microchip. The microchip mounts in a dental prosthetic item for oral use. The external reader when activated can scan and display or otherwise provide access to the information relating to the user. The microchip and dental prosthetic item, when installed in the mouth of the user, are configured to provide access to the information relating to the user at a given time.

The present disclosure provides an oral data collection device comprising a mouthguard and at least two sensors, a medical analytics system comprising the device, and methods of using the device and system to provide a personalized treatment protocol, stage a health condition, measure a response to therapy, phenotype for selection to participate in drug trials, measure stability of an anatomical structure, or predict a rate of change of a health condition in a subject in need thereof.

According to one example, a medical tray for a surgical procedure is disclosed. The medical tray can optionally comprise: a housing; and one or more tray inserts configured to be received within the housing and having a first major surface and one or more support. The one or more tray inserts are configured to receive a plurality of dental surgical instruments via a plurality of receptacles formed therein. The plurality of receptacles having corresponding openings in the first major surface. The one or more tray inserts configured to be at least one of: removable from the housing and configured with the one or more supports so as to be positionable exterior to and independent of the housing, or the plurality of receptacles are angled such that the dental surgical instruments when received therein are positioned at an acute angle relative to the first major surface.

A lubrication information management device includes: a lubrication detector provided to a lubrication unit; an instrument wireless tag provided to an instrument; and a read-write unit which is either an antenna or a reader-writer. Moreover, the read-write unit communicates lubrication information to the instrument wireless tag when the lubrication detector detects any of lubrication of the instrument and an operation for lubrication. This makes it possible to reliably manage the lubrication of a dental instrument.

A drivetrain assembly (100, 200) for a personal care device (10), the drivetrain assembly including a resonator (110) connected to a transmission component (24) configured to transmit oscillations to the removable attachment; and a drive coil (120) configured to oscillate the resonator in a first direction; where the drive coil is configured to generate an installation or removal signal in response to installation or removal of the removable attachment, the installation or removal of the removable attachment generating movement of the resonator in a second direction; and where the drivetrain assembly is configured to communicate the generated signal to a controller.
