Abstract: A method includes determining depth values associated with a first set of pixel locations in a first image of a mouth. One or more function is generated for one or more color channels based on intensities of the one or more color channels at the first set of pixel locations and depth values associated with the first set of pixel locations. Image data comprising a new representation of the teeth is received, wherein the image data comprises a second set of pixel locations and new depth values associated with the second set of pixel locations. A new image is generated based on the image data and the one or more functions.

Abstract: Non-sliding orthodontic appliances may include an archwire having male fasteners for locking in place with brackets in a non-sliding manner and interproximal loops for exerting forces on the brackets. Appropriate forces may be calculated according to vectors between initial and ideal tooth positions. The brackets may be transferred to a patient's teeth using indirect bonding trays which contain slots for holding and aligning each bracket. The trays may include integrated handles for facilitating handling, may be sectioned into smaller pieces for easier application, and/or may be labeled for facilitating proper registration. Superposition of a digital placement plan and clinical model after bonding may illustrate the accuracy of bracket placement. The archwire may comprise atraumatic ends to avoid patient discomfort. A color registration system can be used to facilitate the attachment of the archwire to the brackets. The archwire may be locked into place with the brackets using crimpable stops.

Abstract: A finger shield combination and method for using the same for improved dental hygiene during the flossing of teeth. First and second finger shields have tubular sheaths for receiving first and second fingers. Adhesive tabs can be adhered partially to the tubular sheaths and partially to the fingers of the user to constrict the tubular sheaths and retain the finger shields. The adhesive tabs can be angled proximally past the proximal ends of the finger shields and can separably couple the first and second finger shields. The first finger shield can be applied to a forefinger, the second finger shield can be applied to a thumb, and a third finger shield can be applied to the middle finger. At least one stave disposed longitudinally along the tubular sheath of one of the finger shields can prevent constriction by the dental floss.
