A visual tooth cleaning, grinding and polishing instrument includes a host, an oral observation instrument and a cleaning and polishing tool. The host can drive the cleaning and polishing tool and supply a power source and a control system for an illuminating system, an observation system and the oral observation instrument. A picture shot by a camera of the observation system can be transmitted to a display of the observation system in time, so as to achieve the purposes of cleaning the teeth while observing a process of cleaning the dental calculus, dental plaque and pigmentation on the surface of the teeth with the cleaning and polishing tool and the cleaning effect instantly on a mobile phone, thereby effectively cleaning, grinding and polishing the teeth. A flusher or an electric toothbrush head or other interdental cleaning tools may also be mounted on the host or the oral observation instrument.

An oral body device is provided for attaching to and detaching from an oral appliance that has an electrical connection portion. The device includes a body, and an attachment/detachment operation unit that has an electrical connection conductor and is configured to detachably attach the oral appliance to the body portion by operating application and release of force to the oral appliance. Moreover, the attachment/detachment operation unit fixedly attaches the oral appliance in a state in which the electrical connection portion is electrically connected to the electrical connection conductor by applying a force to the oral appliance, and releases the fixation by releasing the force applied to the oral appliance to detach the oral appliance.

An intraoral scanner comprises a light source, a moveable opto-mechanical module, an axial actuator, and an image sensor. The light source is configured to generate light that is to be output onto an object external to the intraoral scanner. The moveable opto-mechanical module comprises integrated projection/imaging optics and an exit pupil, the projection/imaging optics having an optical axis, wherein the projection/imaging optics are entirely integrated into the moveable opto-mechanical module. The axial actuator is coupled to the projection/imaging optics and configured to move the moveable opto-mechanical module comprising an entirety of the projection/imaging optics in the optical axis to achieve a plurality of focus settings. The image sensor is configured to receive reflected light that has been reflected off of the object external to the intraoral scanner for the plurality of focus settings.

A method of multimodal scanning may include generating surface scan data of an intraoral structured using structured light. The method may include generating volumetric scan data of an internal structure of the intraoral structure with OCT scanning. The OCT scan data may be aligned with the surface scan data. A three-dimensional volumetric model of the patient's dentition may be generated based on the aligned OCT scan data and the surface scan data.

A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

A scanner for scanning a dental site comprises a base, a detector mounted to the base, and an optical element to redirect light reflected off of the dental site towards the detector along a detection axis in a first direction. Two or more flexures couple the optical element to the base, wherein the two or more flexures maintain an alignment of the optical element to the detector with changes in temperature.
