Systems and methods for providing at least one fixture for use in an image guidance system for determining a registration coordinate mapping between a human jaw and a volumetric image of that jaw. The system includes one or more channeled trays and a moldable thermoplastic material for inserting into a channeled tray. The moldable thermoplastic material is hardenable into an impression part such that when mated to the at least a portion of the human jaw and held within the channel of the channeled tray, the impression part resists displacement relative to the human jaw. At least one channeled tray in the system includes a fiducial region detectable in the volumetric CT image in a fixed spatial relation relative to the coupling surface region and at least one channeled tray is pose-trackable by the image guidance system.

Systems and methods for rapidly and reliably determining an arch with of a patient's dental arch. A patient's dentition may be scanned and/or segmented. Arch width may be determined between points of intersection on the occlusal surface and a long axis of each tooth between one or more of: canine, first bicuspid, first primary molar, second bicuspid, second primary molar, and permanent first molar. Arch widths of different modified versions of the patient's dentition may be dynamically compared the patient's starting dentition, or to each other, and may be dynamically updated as the user modifies or switches between one or more 3D models of the patient's dentition.

A kit of dental instruments for intraoral scanning includes first instrument and second instruments for a patient’s left and right side lower arches, respectively, at least a third instrument for the upper arch. The first instrument includes a first handle with rectangular profile and rounded edges and two arms, the latter being a first left lateral arm on whose body a scanner slides, and a second front arm, the arms being extractible and interchangeable. The first lateral arm inserts in the handle through holes, the second instrument being the mirrored copy of the first instrument and including a second handle analogous to the first handle and with rounded edges and two arms, the latter being a first right lateral arm and a second front arm analogous to the second front arm for the left side, the kit further including at least a third instrument for the upper mouth arch.

A computer system and method for intelligent diagnosis are provided. The system comprises at least one processor and a memory storing instructions which when executed by the processor configure the processor to perform the method. The method comprises receiving an initial appoint request, receiving a first scanning appointment request, sending a movable practice to patient location, receiving scanning data, and sending the scanning data to remote server for processing.

An off-the-shelf oral splint that is operatively secured to the maxilla and mandible to assist in reduction and provide maintenance of reduction of maxillary and mandibular fractures in the edentulous or partially edentulous patient. The oral splint is fabricated into a plurality of standardized sizes. These sizes are determined by imaging a population of jaws, measuring dimensions thereof, manipulating (e.g., calculating the mean) these dimensions, and generating a size that is representative of a subset of that population. This can be done for all sizes that would represent individuals in that population. The splint itself is fabricated virtually by creating “U-shapes”, splitting them horizontally into halves, creating an evacuation channel, and generating a coupling mechanism to hold the halves together. The splint can then be printed or otherwise manufactured.

Embodiments for estimating a surface texture of a tooth are described herein. One method embodiment includes collecting a sequence of images utilizing multiple light conditions using an intra-oral imaging device and estimating the surface texture of the tooth based on the sequence of images.

Disclosed are methods and digital tools for deriving tooth condition information for a patient's teeth, for populating a digital dental chart with derived tooth condition information, and for generating an electronic data record containing such information.

A method of collecting dental measurements comprising: receiving optical measurement data of at least a portion of a subject's mouth; contacting a portion of a measuring device to portions of the subject's mouth to collect position measurement data, where the measuring device includes a tracker; and combining the optical measurement data and the position measurement data.

The disclosed technology provides for setting up teeth, such as dentures and dental appliances, based on motion data. A method can include receiving, by a computing system, a digital representation of the patient's jaw movement, receiving a digital model of at least a portion of the patient's upper and lower teeth, receiving user input indicating selection of at least a first tooth in the digital model as moveable, at least a second tooth as fixed, and at least a third tooth as ignored, moving the at least portion of the upper teeth and the lower teeth along movement pathways indicated by the digital representation of jaw movement, and automatically adjusting a position of the selected first tooth based on detecting the position of the selected at least first tooth as colliding or interfering with one or more other teeth represented by the digital model along one of the movement pathways.

An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.
