Methods and tools for expanding a precursor hole in a host material to receive an anchor or fixture. The precursor hole is enlarged by a rotary tool having helical flutes and interposed lands. The lands each have a working edge that densities bone when the tool is rotated in a non-cutting direction. When the tool is used with a copious wash of irrigating fluid, hydraulic pressure builds inside the precursor hole. The operator can modulate the hydraulic pressure by axially stroking the rotating tool. The working edges sweep against the interior surface of the hole to gently expand its diameter by incremental plastic deformations with little to no removal of host material. The host material may be bone and the hole formed may be an osteotomy that is prepared with dense, compacted sidewalls to receive a bone implant with a high degree of primary stability.

Provided is a detection tool that detects a temperature of air. The detection tool includes a detection section that detects a temperature of air released from an air turbine handpiece, and a main body that includes a surface. The detection section is provided on the surface to allow the air turbine handpiece to be brought close to the detection section.

This invention is achieved to provide a water-flow ultrasonic oral-cavity cleaning device. In the water-flow ultrasonic oral-cavity cleaning device (1), cleaning liquid (W1) from a cleaning-liquid supplying device (2) is supplied into a transducer case (21) through a supply port (26). Ultrasonic waves (S1) are propagated into the cleaning liquid W1 from an ultrasonic transducer (22) mounted in a transducer mounting part (23) inside the transducer case (21). The water-flow of the cleaning liquid (W1) is collected at the apical-part inside the transducer case (21), and then emitted from the issue (27) into the oral cavity, wherein power supply of 100W or less is supplied to the ultrasonic transducer (22) of 50 mm or less in diameter to propagate the ultrasonic waves (S1) of 100 kHz or more to 3 MHz or less in frequency into the cleaning liquid (W1).

The present disclosure relates to a tooth cleaning device having an internal fluid conduit 58 formed therein, and the tooth cleaning device includes: a main body 10 which has a tube T1 provided in the main body 10 and selectively connectable with a drive unit 100; and a cleaning body 50 which is assembled to one side of the main body 10, and has the internal fluid conduit 58 formed in the cleaning body 50 and connectable with the tube T1, in which at least one nozzle 65 is formed to be opened at one end of the internal fluid conduit 58. Further, when the main body 10 and the cleaning body 50 are assembled, one end of the tube T1 is connected to one end of the internal fluid conduit 58 so as to form a single continuous flow path, and through the single continuous flow path, a cleaning solution may be discharged or a fluid is sucked and then discharged to the outside. According to the present disclosure as described above, the main body 10 and the cleaning body 50, which constitute the tooth cleaning device, may be assembled and disassembled, and as a result, it is possible to repair, replace, or wash some components such as the tube T1 and the internal fluid conduit 58 by disassembling the components.

A tip-based computer controlled system for a dental delivery device is disclosed. The system automatically controls an operating characteristic such as power control or fluid flow based on tip identification and history. The operating characteristic may also be controlled in response to particular conditions throughout the dental procedure, such as (but not limited to) temperature, dental hygiene material, fluid type, etc. The system may provide an alert or shut off if unsafe conditions occur and/or error circumstances are detected. An operator interface is provided to configure the system and augment/override an executing control algorithm during a procedure. A method and a computer-readable storage medium are also disclosed.

A valve assembly for a dental suction system. The valve assembly includes a valve body having an inlet, an outlet and a fluid flow path extending between the inlet and the outlet. The valve assembly also includes a valve plug positioned at least partially within the valve body and including a through-passage. The valve plug is rotatable relative to the valve body to selectively alter a flow of fluid along the fluid flow path. The fluid flow path exhibits a varied cross-sectional area along a length of the fluid flow path.

The appliance includes a jet source of fluid, and a nozzle assembly (10) through which the fluid is directed and then out for application to the teeth. A flow interrupter assembly is mounted within the nozzle assembly, such that the interrupter assembly (20) is responsive to the fluid flow to produce momentary successive interruptions of the fluid flow by the action of the interrupter assembly moving from an original position to a flow interrupting position and then returning to its original position as the flow decreases and then is interrupted, due to the fluid flow itself, resulting in a cyclical perturbation in the fluid flow from the nozzle, by flow action alone.

A tailpiece for a dental valve device is disclosed which has a body having a valve receiving end, a hose receiving end, and an intermediate elbow portion between the valve receiving end and the hose receiving end. A tailpiece for a dental valve device is also disclosed which has a body having a valve receiving end, a hose receiving end, an intermediate elbow portion between the valve receiving end and the hose receiving end, a lumen formed in the body between the valve receiving end and the hose receiving end, and a check valve positioned in the lumen.

A dental treatment system can include a console, a tooth coupler, and an interface member that provides at least one of fluidic, electrical, mechanical, and data communication between the tooth coupler and the console. The tooth coupler (which may comprise a handpiece or a treatment cap) can act as a working end of the system to administer a suitable treatment procedure, such as a cleaning procedure, an obturation procedure, a restoration procedure, etc. The tooth coupler can removably engage the interface member such that the clinician can easily engage and disengage the tooth coupler and interface member.

Embodiments of the invention include a handpiece system including a detachable cable that can receive at least power, and a detachable cable connector, where the detachable cable connector and detachable cable are reversibly attachable to each other. In some embodiments, the system includes an interchangeable laser module, where the laser module and detachable cable connector are reversibly attachable to each other. Further, the interchangeable laser module is configured and arranged to receive at least the power via the cable connector when coupled to the cable connector, and to be removed from the detachable cable connector and replaced with another laser module. In some embodiments, the system further includes an interchangeable handpiece which is reversibly attachable to the interchangeable laser module. Further, the interchangeable handpiece is configured and arranged to be removed from the interchangeable laser module and replaced with another interchangeable handpiece.
