A method, system and a computer readable storage media for operating dental machines through an augmented reality control interface A hands free interface may enable the control of a dental machine during dental treatment by using dexterous parts of the body other than the upper limbs (e.g. by using the lower limbs) on a first user/control interface to send instructions corresponding to a second user/control interface that is different from the first user/control interface.

The present invention provides a working angle guiding device for dental implant and a method thereof. The working angle guiding device includes an intraoral securing device, a hand-held tool, a first triaxial attitude information sensor, a second triaxial attitude information sensor, and a controller. The working angle guiding method includes a preparing step, an installing step, a correcting step, a moving step, and a working angle adjusting step. The relative angle information of the first triaxial attitude information sensor and the second triaxial attitude information sensor is utilized to assist and guide the dentist to acquire the angle of implant drilling. The present invention has advantages in that the triaxial angle of the drill hole can be confirmed even after the patient dodges, tilts or moves his/her head, and that the first triaxial attitude information sensor can be flexibly mounted in the mouth or outside the mouth.

A dental unit, which comprises connections for instruments and a control device and a microprocessor, which is arranged to control the dental unit. According to the invention, the microprocessor is arranged to control the dental unit according to a user specific user profile and the dental unit comprises a function for reading the user profile or a part of the user profile from an external record. The external record can be e.g. an USB memory stick or a record readable via a data network.

A laser beam treatment system that delivers laser beam pulses to a dental treatment area according to a particular pattern is described. In various instances, the spacing of the pattern (e.g., locations at which pulses are delivered and the distances therebetween) and/or the timing of the pattern (e.g., amount of time between the delivery of pulses to a first location and a later location that abuts the first location) can have a demonstrable effect on ablation performance. The effects can include, for example: improved ablation efficiency, improved surface smoothness, improved material removal rate, and/or the absence of melt, carbonization or other negative surface features.

The present invention provides for devices and methods of treating wounds, including general wounds, gum disease and gingival tissues post scaling/root planning, using a diode laser which generates a beam of light having a wavelength in the visible portion of the electromagnetic spectrum (400 nm-700 nm). Further disclosed are devices and methods capable of stimulating tissue regeneration at the site of a wound.

An oral irrigator has a first liquid container, a nozzle outlet, a pump driven by a drive to pump liquid from the liquid container to the nozzle outlet so that a liquid jet is emitted via the nozzle outlet, a first switch arranged so that the drive is powered when the first switch is actuated once and the oral irrigator is switched into an ON state, and so that powering of the drive is stopped and the oral irrigator is switched into an OFF state when the first switch is actuated once again, and a second switch arranged so that the drive is powered only while the second switch is continuously actuated by the user and powering is stopped when the second switch is released.

This disclosure relates to various systems and methods related to preventative laser-based treatment of a dental tissue; for example, to prevent a patient from forming cavities. In some instances, a laser-based treatment system can generate a laser beam pulse with a fluence profile at a treatment site that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. In some instances, the laser-based treatment system can direct the laser beam to various locations within a treatment site according to a temporal and/or spatial pattern, that results in either an increase in acid resistance of the tissue or removal of carbonate from the tissue, without melting or ablating the tissue. Many other systems and techniques for preventative and other laser-based treatment are also described.

Embodiments relate to a systems and methods for preventative irradiative dental treatment. In accordance with one embodiment, a system and method include using a radiation source to generate a radiation; using an optic disposed to accept the radiation to internally reflect he radiation at a first end; using at least one side of the optic to contact a dental hard tissue; using the optic to couple some of the radiation into the dental hard tissue; and, using a controller to control a parameter of the radiation to heat a surface of the dental hard tissue.

A light source for emitting light, a light conduit in electromagnetic communication with the light source for communicating light from the light source to the area of interest in three dimensions, and a controller combined to the light source for controlling the intensity of the light emitted to the area of interest.

A method treating a root canal in a tooth by introducing into the pulp chamber of a tooth and pulsing a laser light into the fluid reservoir so as to disintegrate pulp within the root canal without generation of any significant heat in said liquid fluid so as to avoid elevating the temperature of any of the dentin, tooth, or other adjacent tissue more than about 5° C.
