Described herein is a dental material applicator system comprising a segmented capsule and handpiece. The capsule separately holds a powder and a liquid such that upon activation in the handpiece by an operator, the powder and liquid are mixed into a paste. The operator then triggers the handpiece so that the mixed paste is extruded.

The disclosure is directed to systems and methods for treatment of periimplantitis using ultraviolet light. In some embodiments, the ultraviolet light is ultraviolet c light with a wavelength between 100 and 280 nanometers. In some embodiments, the ultraviolet c light makes the surface of the implant hydrophilic and more receptive to cell protein attachment. In some embodiments, an apparatus for treating periimplantitis using ultraviolet light includes a handpiece with a flexible neck and a rotatable tip at the end of the flexible neck. In some embodiments, the handpiece includes a contra angle dental handpiece or a straight dental handpiece which can couple to and direct ultraviolet light from either an end firing tip or a side firing tip. In some embodiments, the handpiece is sized to enable UVC light to be directed to an exposed area of an implant facing toward one or more posterior portions of the oral cavity.

The present disclosure provides a device having a circuit. The circuit includes at least one boost converter receiving power from an energy source, a square wave driver in series with the boost converter, an inductor in series with the square wave driver for converting a square wave to a sinusoidal wave, and a piezoelectric transducer in series with the inductor, the piezoelectric transducer connectable to a load. The device further includes a phase-locked loop coupled to the circuit to determine a resonance frequency of the piezoelectric transducer when the piezoelectric transducer is connected to the load.

A system comprises an image capture device, an augmented reality (AR) display to display, and a processing device. The processing deice receives image data of a dental arch from the image capture device and processes the image data using a plurality of detection rules, where each detection rule detects one or more dental conditions. The processing device determines a dental condition for the dental arch based on the processing, determines a position of an area of interest on the dental arch, wherein the area of interest is associated with the dental condition, generates a visual overlay comprising an indication of the dental condition at the position of the area of interest, and outputs the visual overlay to the AR display, wherein the visual overlay is superimposed over a view of the dental arch on the AR display at the position of the area of interest.

The invention comprises a light curing device with a light source (30) and a light guiding device, in particular a light guiding rod (18) with a light entry surface (31) that extends next to the light source (30) if regarded in the emission direction of the light source (30), and with at least one sensor (36) that is arranged next to the light entry surface (31), and with a control device (32) that is arranged within a handpiece (14) of the light curing device (10). The light curing device (10) further comprises a base station (12) of the light curing device (10). The base station (12) is provided with a second light source (24) and a second light sensor (26) for the bidirectional optical communication with the handpiece (14), which bidirectional communication takes place through the light guiding device (light guiding rod), in particular in the frequency range of visible light or UV light and in particular in a modulated manner.

Provided herein are computer-implemented methods, computer-implemented systems, and a non-transitory computer-readable storage media for directing an automated dental drill (ADD) for preparation of a target tooth of a patient under the control of a practitioner

The present invention concerns a control system (1) for a micro-motor for dental or surgical use comprising a control box (10) provided with an adjustment knob (2), mounted in a way rotatable about a rotational axis (A-A). The adjustment knob (2) is made up of a control support (20) integral with an encoder (3) integrated in the said box (10), and a sterilizable button (21) coupled in a removable way to the said control support (20).

A lightweight, small footprint, composite extraction pen, for the delivery of dental filling composite from commercially available composite filled carpules. An electric linear actuator is housed in a slender, pen-like housing configured to accept, constrain and allow the rotational positioning of commercially available composite filled carpules. The carpules are contained within an adaptor that connects to the body of the pen. The linear actuator extends and retracts a piston through a bore in the carpule so as to exert pressure on the composite contained therein. The pen provides precise composite delivery while maintaining a highly visible dental environment.

A method for continuously evaluating the effectiveness of debridement of a root canal of a tooth, the tooth having an open access cavity and an apex end, includes delivering a fluid to the open access cavity of the tooth, evacuating the fluid near the apex end of the tooth such that the fluid flushes most of the root canal before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris, a concentration level of the debris, or a type of the debris. An apparatus for use in debriding a root canal of a tooth includes a microcannula or a macrocannula configured to evacuate a fluid in the root canal, and a sensing mechanism fluidically coupled to the microcannula or the macrocannula, the sensing mechanism configured to continuously sense debris in the evacuated fluid in real time.

A tracking and guidance arrangement for a surgical robot system and related method are provided. The arrangement includes a patient-interacting device including an instrument engaged a distal end of a guide arm and a fiducial marker coupled to maxillofacial anatomy of the patient. A detector is connected to an articulating arm and co-operable therewith to be positioned adjacent to the fiducial marker, with the detector being configured to interact with the fiducial marker. A controller device is configured to receive data from the detector relative to the interaction thereof with the fiducial marker, to determine a spatial relation between the fiducial marker and the detector based on the data, to determine a spatial relation of the instrument relative to the fiducial marker, and to direct the instrument to interact with the maxillofacial anatomy of the patient according to the determined spatial relations.
