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.

Apparatus and methods for providing three-dimensional printed oral stents are provided for head and neck radiotherapy. Movement of the jaw of the patient is simulated via a computer processor. Simulating movement of the jaw of the patient comprises rotating and translating a mandible of the jaw. A digital negative impression is transformed into a digital oral stent by adding support structures to the digital negative impression. The support structures facilitate three-dimensional (3D) printing of the patient-specific oral stent.

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.

An approach is disclosed that involves creating an updated master dental model of a patient's mouth after an implant surgery by aligning new postoperative oral scan data to pre-existing preoperative oral scan data that is more comprehensive (e.g., it includes bite registration). Before surgery a multi-piece stackable surgical guide set is created using the preoperative oral scan data. The surgical guide set is used to facilitate the surgery. After the surgery at least one piece of the surgical guide set is placed back in a patient's mouth and may act as a reference marker because it was created using the preoperative oral scan data, but is also part of the postoperative mouth configuration since it was used to facilitate the surgery. The affected portion of the mouth may then be digitally scanned directly or indirectly by way of a physical impression with the reference marker in place to determine the new characteristics resulting from the surgery such as new implant installation locations and orientations. The new postoperative oral scan data may be combined with the pre-existing preoperative oral scan data by way of the reference marker (since it is a constant between the two sets of scan data) without having to do such things as take a new bite registration, on which a new implant restoration can be easily created.

A dental imager includes an elongated handle with a rotatable head coupled to a distal end thereof and having a central platform with a plurality of arcuate scanning arms pivotally coupled thereto by a hinge. The arcuate scanning arms are of a shape and size for general deployment around a tooth and each include at least one scanner and a roller guide that comfortably rolls along the surface of the tooth or gums to bias the scanners a desired distance from the surface of the tooth, conducive for imaging thereof. In this respect, such a dental imager may be used in a process to scan and record the contours of an intraoral surface, the data of which may be used to create a digital three-dimensional surface impression printable by a 3D printer or the like.

A method to visualize and correct alignment errors between paired 2D and 3D data sets is described. In a representative embodiment, a display interface used for dental implant planning includes one or more display areas that enable the operator to visualize alignment errors between the paired 2D and 3D data sets. A first display area renders 3D cone beam data. A second display area renders one or more (and preferably three (3) mutually orthogonal views) slices of the cone beam data. A third display area displays a view of a 2D scanned surface map (obtained from an intra-oral scan, or the scan of a model). According to a first aspect, the view of the 2D scanned surface map in the third display area is textured by coloring the 2D surface model based on the intensity of each 3D pixel (or voxel) that it intersects.

Disclosed is a method for calibrating at least one 2D X-ray image of an object to be imaged, which is recorded by an X-ray device in that X-rays produced by an X-ray source radiate through the object and are recorded by an X-ray detector. An already existing 3D model of a structure of the object is compared to the 2D X-ray image, wherein an actual image positional relationship of the X-ray source and the X-ray detector relative to the object, and/or relative to one another, is determined for the 2D X-ray image.

The application relates to an X-ray imaging unit for a medical imaging. The unit includes a rotating part with a first X-ray source and an X-ray imaging detector unit configured to provide an image with at least a rotational movement (R) around a rotation axis of the rotating part. The unit includes an upper shelf configured to enable the rotating part to move with respect to the upper shelf with a linear movement (L) and to be attached to a column with a pivoting joint for enabling a pivot movement (P) of the upper shelf around the column. The rotating part is configured to be positioned by the linear movement and the pivot movement during the imaging.

Taking a digital implant or abutment level digital impression by means of intra-oral, computed tomography or other imaging method provides the restorative doctor and laboratory accurate and effective data for determining the implant position, angulation and locking feature orientation without a physical impression. Such data is correlated with a digital library to produce an output which enables design and fabrication of an accurate restorative device such as a prosthetic tooth or crown. In this way the time-consuming, costly and error prone mechanical replication of the relevant dental anatomy is obviated.

A system for creating customized root canal obturation cores is provided. The system receives a 3D image data set representing one or more teeth. The system then displays an image of a tooth of the one or more teeth. After receiving at least one user input, the system constructs a 3D output data set from the 3D image data set based on the at least one user input. Next, the system converts the constructed 3D output data set to control data. A computer controlled manufacturing system can use the 3D output data set to manufacture a customized root canal obturation core.
