An intraoral scanner system includes an intraoral scanner having an imaging device and a sensing face, and a computing device, communicatively coupled to the intraoral scanner. The computing device receives a first intraoral images of a three-dimensional intraoral object of a patient generated by the intraoral scanner corresponding to an intraoral scanning of the three-dimensional intraoral object of the patient. The computing device registers a first intraoral image of the first intraoral images relative to a second intraoral image of the first intraoral images using a model of the three-dimensional intraoral object that existed prior to the intraoral scanning.

A control device for controlling a surgical handpiece is suitable for controlling the surgical handpiece according to control parameters. The control device comprises local control means present on the control device, wireless communication means suitable for communicating with remote control means by a wireless communication link. The local control means and the wireless communication means is suitable for receiving instructions to adjust each control parameter. Selector means is provided for selecting either the local control means or the wireless communication means for adjusting each control parameter.

The invention relates to the field of dentistry and is used for reinforcing composite materials to eliminate various defects of dental hard tissues of carious and non-carious origin in the process of direct/indirect and reinforced/non-reinforced composite restorations. The claimed method includes vibrational mechanical activation of composite materials by vibrationally acting upon portions of composite material shaped by manual mechanical activation (e.g., roll/ball) and applied layer-by-layer to the region of a defect. A device for vibrational mechanical activation of a composite material includes at least one working portion for applying a composite material to the region of a defect, the working portion fixedly attached to a handle, which is connected by a framework to a micromotor that creates vibrations which are transferred via the working portion to a layer of composite material by distributing the same across the entire surface of the defect and achieving the simultaneous surface plastic deformation thereof.

A device and a method for making space between teeth that can efficiently form a necessary space between adjacent teeth in a short time and reduce the physical burden on both the patient and the person who gives treatment. The device for making space includes an ultrasonic oscillator, an ultrasonic vibrator which receives a driving signal from the ultrasonic oscillator and vibrates ultrasonically, a grinding tip to which the vibration from the ultrasonic vibrator is transmitted, and a power supply device which supplies power to the ultrasonic oscillator. The opposing surfaces of the adjacent teeth T are ground by ultrasonic vibration of the grinding tip inserted between the two adjacent teeth T.

A medical/dental handpiece comprises a housing having distal portion, the head portion having a bottom surface defining an opening. A motor and a light source are positioned with the handpiece, and the handpiece removably receives a light guide in alignment with the light source, to receive light from the light source. The light guide includes a probe which can be positioned adjacent or within a treatment area. The handpiece can be operated to activate only the light source, such that light is directed through the probe to or into the treatment area, to activate only the motor to rotationally or reciprocatingly drive the light guide, or to activate both the light source and the motor.

A mouthpiece cleaning device includes a U-shaped mouthpiece skeleton that defines opposing channels to receive a user's teeth therein. The channels each have a respective teeth facing surface, and transducers are disposed along the channels at the respective teeth facing surfaces. UV LEDs are disposed along the channels at the respective teeth facing services. The UV LEDs are interspersed with the transducers.

The present disclosure relates to a patient anxiety management system for managing patient anxiety during a dental procedure. In one example, a patient anxiety management system is presented. The patient anxiety management system includes a control module that a patient can use to disactivate a medical device used by a dental professional by way of a trigger mechanism. Upon deactivating the medical device, a recording device, in communication with the control module, plays a recorded message to the patient during a programmable timeframe. Once the patient is calm, the system resets the medical device to an initial operation state by reconnecting but not reactivating the medical device so that the dental professional may resume the procedure when it is safe to proceed.
