Provided herein are devices and methods generating a panoramic rendering of a subject's teeth. Methods and processes are provided to image the subject's teeth with a dental scan. Methods and processes are also provided to automatically 3D render the subject's teeth with the scan images. Methods and apparatuses are also provided to generate simulated panoramic views of the subject's dentition from various perspectives.

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different “faces” of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.

An intraoral scanning system that includes a housing and a sleeve. The housing includes optical components, a head, and a defogging unit that includes a heating unit. The head includes a primary aperture and is configured to be inserted into an oral cavity of a patient. The sleeve includes a secondary optical component arranged at a secondary aperture that is configured to be positioned in alignment with the primary aperture when the sleeve is coupled with the housing. The heating unit is configured to generate heat in response to application of electrical power to the heating unit. When the sleeve is coupled with the housing, the secondary optical component is configured to be arranged such that the generated heat is transferred from the heating unit to the secondary optical component through thermal conduction between the heating unit and secondary optical component.

A computer-implemented method/system of determining a trim-line includes receiving a 3D digital dental model; combining the one or more virtual teeth; determining a distance field; determining a first iso-line; determining a back distance field; determining a second iso-line to generate a trim-line. A computer-implemented method/system of segmenting the 3D digital dental model includes receiving a 3D digital dental model; determining an initial virtual tooth location of one or more virtual teeth; constructing a virtual crown line; determining a long axis of one or more virtual teeth; constructing a virtual root line; determining a virtual tooth virtual bounding box; performing an initial segmentation; performing final segmentation.

The method for generating dental data suitable for manufacturing of a dental aligner, includes storing 3D scan data of a dental arch, determining (140) a curve in an occlusal plane, determining a positioning of the nodes of the teeth of the dental arch on the curve, determining an elevation of the nodes of the teeth of the dental arch, and determining an orientation of the teeth of the dental arch; said manufacturing data are calculated at least on the basis of the 3D scan data as well as the determined positioning, the determined elevation, and the determined orientation.

A unique CAD subtract body intended to create a design of a mating surface for a veneering overlay and a dental implant framework wherein the unique CAD subtract body is derived from a diagnostic wax-up surface model. The diagnostic wax-up surface model is created from at least one of scanning a diagnostic wax up or denture tooth set up, CAD models in a virtual set up, an intraoral scan of a diagnostic wax up or denture tooth set up taken in a patient's mouth, a CT scan or series of CT scans of a patient's mouth, a CT scan or series of CT scans with the use of a radiographic stent in a patient's mouth, and wherein the unique CAD subtract body can be used to create the tool path for the manufacturing of the veneering overlay and allows for the fabrication of a dental implant from at least one of a metallic material, a ceramic material, an acrylic material, a biocompatible material.

Dental retainer devices are provided. The dental retainer devices can be customized based on patient specific dental anatomy and dental treatment plans. Methods of making the dental retainer devices are also provided. The methods can included additive manufacturing. Methods are also provided for customization of a dental retainer device based on the patient specific anatomy. The methods for customization can include providing a dentist with different options for anterior teeth coverage, posterior teeth coverage, and palatal configurations for the dental retainer devices.

A method for obtaining images for assessing oral health using a mobile device (103) having a screen (205) on one side of a housing of the mobile device (103) and a camera (207) on the opposite side of the housing (103), comprising: —on the mobile device (103) performing a dialogue with a user (101) of the mobile device (103), —determining an area of the user's oral cavity with symptoms based on the dialogue, —instructing the user (101) to position him-/herself in front of a minor (102) for capturing an image of the area of the user's oral cavity with symptoms, —capturing at least one image of the area of the user's oral cavity with symptoms with the camera (207) as instructed, and—either processing the at least one image locally on the mobile device (103), or—transmitting the at least one image or a representation thereof to a remote server (409).

The invention relates to a computer system for providing a treatment proposal for a dentition of a patient. The computer system is configured to provide an current state model of the dentition and a target state model of the dentition; to provide a set of treatment options for treating the dentition, to check the provided treatment options, wherein the checking comprises determining whether the dentition of the patient is meeting the feasibility requirements assigned to the treatment option being checked; in case the dentition is determined to meet the feasibility requirements assigned to the treatment option being checked, to provide the treatment proposal identifying the respective treatment option and implementation parameters determined for the measures of the identified treatment option for modifying the current state model such that one or more discrepancies of the current state model relative to the target state model are compensated.

Embodiments relate to the methodology of direct manufacture of a customized labial/lingual orthodontic tube by using a ceramic slurry-based additive manufacturing (AM) technology. For example, a method of manufacturing customized ceramic labial/lingual orthodontic tubes by additive manufacturing may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three-dimensional computer-assisted design (3D CAD) model of the patient's teeth, and saving the 3D CAD model, designing a virtual 3D CAD tube structure model for a single labial or lingual tube structure based upon said 3D CAD model, importing data related to the 3D CAD tube structure model into an additive manufacturing machine, and directly producing the tube with the additive manufacturing machine by layer manufacturing from an inorganic material including at least one of a ceramic, a polymer-derived ceramic, and a polymer-derived metal.
