Abstract: Example fiducial markers include features that make them particularly useful in dental scanning methods for analyzing jaws of a patient, wherein the dental scanning methods involve taking multiple scans of the jaws, and/or models thereof, and then shifting the image of one scan to match that of another. Prior to scanning, the fiducial markers are attached to the patient's jaws to accurately identify and track the relative position of the jaws.

Abstract: Example radiographic dental jigs include a generally vertical post traversed by a generally horizontal beam to create a cross that can be used for marking a dental patient's midline (vertical line centered between the eyes), incisal edge plane, and forward lip position. The jig is radiographically scanned along with multiple fiducial markers on the patient's jaw to generate a first scan result. In some examples, physical models of the patient's jaws are also scanned to generate upper and lower jaw images. The upper and lower jaw images are shifted to coincide with the first scan result. Portions of the first scan result, including an image of the dental jig, are superimposed onto the properly shifted upper and lower jaw images to create a composite image. The composite image shows the dental jig in proper relation to the patient's upper and lower jaws, thereby rendering a conventional stick bite virtually obsolete.

Abstract: Example dental scanning methods for analyzing jaws of a patient involve taking multiple scans of the jaws, and/or models thereof, and then shifting the image of one scan to match that of another. In some examples, fiducial markers are attached to the patient's jaws beforehand to accurately identify and track the relative position of the jaws. The methods provide a way for creating a precise image of an upper jaw and a lower jaw in their proper bite registration, even though the resulting image may show an insufficient number of teeth to readily do so. The final, properly shifted image serves as a virtual 3D jaw model that can be manipulated and analyzed to aid in various orthodontic and other dental treatments.

Abstract: Example dental scanning methods for analyzing jaws of a patient involve taking multiple radiographic scans of the jaws, and/or models thereof, and then applying digital image analytics to shift the image of one scan to match that of another. The resulting properly scaled and shifted image serves as a virtual 3D jaw model that can be manipulated and analyzed to aid in various orthodontic and other dental treatments.

Abstract: Example dental methods involve using a marker transfer jig that captures the location of one or more fiducial markers on a patient's jaw and then helps position an alternate marker, tool, fixture or some other chosen device on a cast model of the patient's jaw. The cast model with the attached alternate marker, tool, fixture or other chosen device is radiographically scanned and analyzed to aid in various orthodontic and other dental treatments.

Abstract: A dental tool for guiding a drill or biopsy punch during a dental implant procedure includes a drill bushing pivotally attached to a bushing holder. The bushing holder, in turn, is attached to a surgical stent that fits a patient's teeth, gums, and/or jaw. The pivotal connection between the drill bushing and the bushing holder allows the angular orientation of the drill bushing to be adjusted, so the trajectory of the drill or biopsy punch can be aimed directly into the patient's jawbone. Once the drill bushing is properly oriented, the bushing is bonded to the bushing holder to prevent further movement between the bushing and the holder.

Abstract: A fish bite alert device includes a 3-position adjustable gripper that provides a positive line gripping action in a set mode yet completely releases the line, entirely free of the fish bite alert device, in a release position. The gripper is illuminated for night fishing. The fish bite alert device also includes a 3-mode selector switch to choose light-only operation, light and buzzer operation, and an off position. The light assists the hearing impaired, while the buzzer is beneficial to the sight impaired.
