An ultrasonic unit manufacturing system and process are based on a universal ultrasonic generator unit that operates interchangeably with either one of piezoelectric and magnetostrictive ultrasonic devices, and optionally as well as with either on-off or power level control footswitches. The ultrasonic units use a generator unit having a detector that determines whether the connected device is piezoelectric or magnetostrictive, and activates the generator for the appropriate piezoelectric or magnetostrictive operating mode. The ultrasonic units so made and methods of using them are also disclosed.

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.

Embodiments of the invention provide a system of controlling a dental laser system. The system can include a dental laser and a control system for controlling certain functions of the dental laser. A graphical user interface can be used to provide input to the control system. The graphical user interface can include a first display and an second display with selectable segments, and a menu navigation portion located adjacent the second display. Treatment categories, procedures or laser control options can be selected using the interface, and the interface can be updated based on data from the station.

The invention relates to a method and an arrangement for the cleaning of a circumferentially closed canal by means of a light guide conducting a laser beam. The entry of the laser beam into the light guide is interrupted when the free end of the light guide is outside of the canal and/or the movement of the light guide within the canal is monitored and that if there is no movement or the movement is below a threshold value then a signal is triggered and/or the laser radiation is turned off or its output is reduced.

An image of a dental arch comprising a preparation tooth is generated by an image capture device associated with an augmented reality (AR) display. The image of the dental arch is registered to previous image data associated with the dental arch. A visual overlay associated with a dental prosthetic to be placed on the preparation tooth is generated based on the registering of the image of the dental arch to the previous image data associated with the dental arch. The visual overlay is output to the AR display, wherein the visual overlay is superimposed over a view of the preparation tooth on the AR display.

A method for wireless transmission of data in a medical or dental system which has a foot control and at least two devices which can selectively be controlled wirelessly by the foot control, each device being assigned a specific identification code, wherein a controller provided in the foot control selects on the basis of data packets the device to which operating data are wirelessly transmitted, wherein each of the devices has its own data packet which comprises the specific identification code of the device and an individual rank assigned to this device of a ranking of the devices.

A motor driven syringe dispenser which has a syringe mounting part, a slider, and a connection for an endodontic motor. The syringe dispenser connects to an endodontic motor which is used to drive a plunger of a syringe placed in the syringe mounting part thereby expressing irrigant into a root canal for root canal therapy.

A portable oral irrigator includes a charging seat assembly, a water container assembly, a housing assembly and a pump assembly. The charging seat assembly includes a charging seat base, a transparent charging seat member on the charging seat base, a first control board in the charging seat base, a first light guide line in the transparent charging seat member, a second light guide line in the charging seat base, a charging seat cover on the transparent charging seat member, and a charging socket projecting out of the charging seat cover. With provision of the charging seat assembly, the water container assembly, the housing assembly and the pump assembly, the pump unit draws water from the water container body and exits the water through the nozzle. The first and second light guide lines and the light guide strip emit light to indicate a current state of the oral irrigator.

Various configurations for a pump for oral irrigators. In one embodiment, a pump is disclosed that includes a connecting rod and a piston. The piston includes a sidewall defining a piston cavity and a rod cutout defined in the sidewall where the rod cutout enables insertions of a portion of the connecting rod into the piston cavity, where after insertion the connecting rod extends from the piston cavity past a bottom edge of the sidewall.

A dental treatment apparatus includes a handpiece holding a cutting tool in its head, a drive portion driving the cutting tool held by the head, and a control portion controlling the drive portion in accordance with a drive sequence. The drive sequence includes at least one forward rotation drive for rotating the cutting tool in a cutting direction to cut a treatment portion and at least one reverse rotation drive for rotating the cutting tool in a non-cutting direction. Under the control of the drive portion in accordance with the drive sequence, a cumulative amount of rotation which is an accumulation of an amount of rotation in forward rotation drive and an amount of rotation in reverse rotation drive does not exceed a set value at any time point.
