Height measurement and feedback control keep the tooth-base material interface precise despite shrinkage and tolerance variation.
Separate brushing and rinsing motors enlarge the handle; an integrated sonic motor shares the drive for a more compact oral care device.
Different-wavelength LEDs and a solid convex mixing element create uniform irradiation for more reliable dental material curing.
Multiple measurement electrodes segment the root canal to detect lateral branches simultaneously, eliminating time-consuming gradual insertion processes.
An aerial drone platform carries a communication device alongside an electric toothbrush to enable wireless operation during brushing.
An acoustic motor oral care device integrates a flushing flow path through its power output shaft to reduce overall volume.
A dental light irradiation device switches between curing and camera modes to conserve battery power.
