The present disclosure provides computing device implemented methods, computing device readable media, and systems for motion compensation in a three dimensional scan. Motion compensation can include receiving three-dimensional (3D) scans of a dentition, estimating a motion trajectory from one scan to another, and calculating a corrected scan by compensating for the motion trajectory. Estimating the motion trajectory can include one or more of: registering a scan to another scan and determining whether an amount of movement between the scans is within a registration threshold; determining an optical flow based on local motion between consecutive two-dimensional (2D) images taken during the scan, estimating and improving a motion trajectory of a point in the scan using the optical flow; and estimating an amount of motion of a 3D scanner during the scan as a rigid body transformation based on input from a position tracking device.

Systems and methods for intraoral scanning include determining, by an appointment management system, a condition that a completed in-home dental impression kit has not been received from a user, generating and communicating a message to the user based on the condition where the message prompts the user to schedule an appointment at an intraoral scanning site, receiving a request to schedule an appointment at the intraoral scanning site where the intraoral scanning site has an intraoral scanner configured to conduct an intraoral scan of a mouth of the user, scheduling the appointment based on the request, and conducting the intraoral scan using the intraoral scanner at the intraoral scanning site where the intraoral scan generates three-dimensional data of the mouth of the user.

A method for analyzing a quality of a dental aligner includes receiving, by a processor, a digital dental aligner generated based on a fabricated dental aligner, analyzing, by the processor, the digital dental aligner to identify a quality characteristic of the fabricated dental aligner, determining, by the processor, that the quality characteristic is anomalous, and flagging, by the processor, the fabricated dental aligner indicating that the fabricated dental aligner is rejected in response to determining that the quality characteristic is anomalous.

Disclosed are a charging cradle and a portable radiography device including the same, which is capable of displaying the residual battery capacity when the portable radiography device is being charged and even when not being charged and, more specifically, displaying the possible number of times of radiography in real time by using the residual battery capacity, such that a user can exactly determine when to charge. The portable radiography device includes a radiography device main body having a rechargeable battery, a first communication unit provided in the main body to transmit battery charging state information, a charging cradle configured to receive external power to supply charging power to the battery, a second communication unit provided in the charging cradle to receive the battery charging state information from the first communication unit, and a display unit provided in the charging cradle to display the battery charging state information.

An HTML web browser based imaging system which supports acquisition of 2D x-ray radiographs and which includes either a 2D x-ray imaging device or a 2D color imaging device and a client device located in a dental office. Software operating upon the client device and a cloud server with dental imaging software installed and means to receive and store images or image data. The client device and the cloud server are connected either directly or indirectly via either an internet connection or a VPN connection. The client device has capability of the HTML web browser so that it does not require either an add-on extension or plug-in in order to control acquisition of images from a dental x-ray sensor. The software communicates with the dental x-ray sensor and receives image or image data from the dental x-ray sensor. The software receives direction to initiate acquisition and/or to receive image or image data via communication from the application server and/or from the HTML web browser.

An probe body comprising: one or more light sources; one or more light sensors; an x-ray detector configured to detect, using at least one of the one or more light sensors, light from a scintillator for converting extra-orally applied x-rays to light; and a lower energy light detector configured to detect, using at least one of the one or more light sensors, light from an object illuminated by at least one of the one or more light sources.

A method, system and computer readable storage media for segmenting individual intra-oral measurements and registering said individual intraoral measurements to eliminate or reduce registration errors. An operator may use a dental camera to scan teeth and a trained deep neural network may automatically detect portions of the input images that can cause registration errors and reduce or eliminate the effect of these sources of registration errors.

The present invention is an improved barrier-contained radiological sensor holder. In particular, the present invention is directed to radiological sensor holder contained in a barrier to reduce or prevent contamination. The radiological sensor holder preferably comprises a sensor holder at least partly contained within a barrier having a closed end and an open end. The barrier preferably comprises elastomer latex material and the sensor holder preferably comprises a polymer-based material with a treated surface or material characteristics amenable to anchorage of the elastomer. Alternatively, the holder is a wood pulp-based material with naturally coarse or irregular surface characteristics providing anchorage infusion of the elastomer. The sensor holder preferably has a sleeve with a base, first and second sides, and an opposing face and a bite wing integrally formed with the sleeve along a spine on the base. The sensor holder may alternately include an expansion slot along the opposing face.

A dental imaging system may include an X-ray source, a first optical alignment device, and a dental image collection device. The dental image collection device may include a mouthpiece, at least one electronic X-ray sensor carried by the mouthpiece, and a second optical alignment device carried by the mouthpiece and cooperating with the first optical alignment device to facilitate optically aligning the mouthpiece with the X-ray source. The system may also include a dental image processing device coupled to the at least one electronic X-ray sensor.

Systems and methods for arranging an intraoral scanning at a selected location. A user can request an appointment at a selected intraoral scanning site from a plurality of intraoral scanning sites. In requesting the appointment at the intraoral scanning site, the user can provide various information for reserving the appointment. The user can make the request online (e.g., via an internet scheduling website associated with the intraoral scanning site). The request can also include a selected time for the appointment. The schedule for the selected intraoral scanning site can be analyzed to determine that the selected time for the appointment is available. When the appointment is scheduled for the user, one or more automatically generated messages can be communicated to the customer.
