The present disclosure provides methods, computing device readable medium, devices, and systems that utilize a cheek retractor and/or a mobile device holder for case assessment and/or dental treatments. One cheek retractor includes a first and a second lip holder, both including imaging markers of a predetermined size to determine a scale of teeth of a user, where each imaging marker is located a predefined distance from the remaining imaging markers, and where the lip holder is to hold a cheek away from a mouth of a user to expose teeth of the user. A mobile device holder can include elements to receive a mobile device to capture images of the patient's teeth.

The present invention provides an improved orthodontic bracket with integrated piezosensor chip determining even the slightest change in initial installation setup of orthodontic bracket system and further notifying the subscriber electronically comprising of orthodontic bracket, for holding the tooth; at least one wire, for connecting the orthodontic brackets; and at least one sensor chip placed on the bracket and/or on the wire, wherein, at least one pulse oximeter is installed at the periphery of the bracket base to ensure force applied are within biological limits; the invention provides a detachable wireless frequency transmitter to be placed on the bracket of tie-wing to permit clinical recycling of the bracket; and optionally allowing a handheld laser scanner/photospectrometer to measure the frictional coefficient between the archwire and bracket to determine exact amount of force required for tooth retraction; to determine the bonding technique for detecting voids in adhesive; and to determine the distance between forces applied and center of mass of the tooth.

Systems and methods are disclosed for processing and storing acquired data relating to one or more dental conditions. The methods can include acquiring a first oral feature in a first data acquisition using a data acquisition device, determining a first oral feature first reference point from the first data acquisition, diagnosing a first dental condition upon confirming that the first oral feature first reference point is associated with the first dental condition, acquiring the first oral feature in a second data acquisition using the data acquisition device, determining a first oral feature second reference point from the second data acquisition, and tracking the progression of the first dental condition by determining a discrepancy between the first oral feature first and second reference points.

A method for monitoring the positioning of the teeth including production of a three-dimensional digital initial reference model of the arches of the patient and, for each tooth, definition, from the initial reference model, of a three-dimensional digital reference tooth model; acquisition of updated image of at least one two-dimensional image of the arches in actual acquisition conditions; analysis of each updated image and production, for each updated image, of an updated map; optionally, determination, for each updated image, of rough virtual acquisition conditions approximating the actual acquisition conditions; searching, for each updated image, for a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, for each tooth model, comparison of the positionings of the tooth model in the initial reference model and in the reference model obtained at the end of the preceding steps to determine the movement of the teeth.

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.

The present disclosure includes method, system, apparatus, and indicator embodiments. One apparatus includes an appliance for placement over one or more teeth and a release agent receptacle including an outer portion provided on appliance surface, an inner portion provided within the outer portion, and one or more apertures formed in the outer portion.
