The aligner manufactured includes an edge that correlates with the trimline according to the machine code. A margin point may be proximate a gingival zenith. At least one tooth cooperates with the modeled gingiva to define a line around the tooth.

Systems and methods of defining a trimline in relation to modeled teeth including a three-dimensional model of one or more intraoral surfaces of the patient. The trimline is for use to manufacture an aligner. For one or more pairs of adjacent teeth, a scallop plane is defined based on a scallop factor. The scallop plane is used to determine the position of scallop points on a line around each tooth adjacent to an interproximal region of the pair of teeth. Transition points are then defined on the line around each tooth apically of the scallop points, and the points connected to form an initial connector curve. The initial connector curve is projected on to a mesh of the three-dimensional model, and smoothing applied to the resulting segmented connector curve. The smoothed connector curves are then joined by teeth curves to form the trimline.

Moving includes at least one of rotating and translating an imagery (30, 50) and may be relative to a characteristic feature (118) of the tooth (66) in the imagery (140). The tooth may be an anterior tooth, such as an incisor (62). Cross-sectioning may be at the characteristic feature (118) in a sagittal plane (124), a transverse plane (128), and a coronal plane (126). And, moving may include at least one of rotating and translating the imagery (30, 50) on a plane-by-plane basis in each plane (124, 126, 128). The method may include evaluating an error in the position of the imageries (30, 50) and repeating moving the imageries (30, 50). A dental registration system (200) includes a first imaging system (14, 40) and a second imaging system (14, 40) to capture different imageries (30, 50) of the teeth.

Aesthetic orthodontic bracket and method of making same
An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and movable member are made from a transparent or translucent ceramic for improved aesthetics. The bracket body may include one or more stop surfaces that limit movement of the moveable member in the gingival direction. The bracket body may include a support surface that is positioned lingually of a labial edge of the archwire slot. The moveable member may include a bracket-engaging portion having a first surface confronting the bracket body and a slot-covering portion having a second surface confronting the archwire slot, the first and second surfaces being offset from one another.
A method for continuously evaluating the effectiveness of debridement of a root canal of a tooth, the tooth having an open access cavity and an apex end, includes delivering a fluid to the open access cavity of the tooth, evacuating the fluid near the apex end of the tooth such that the fluid flushes most of the root canal before being evacuated, and continuously evaluating the evacuated fluid for at least one of a presence of debris, a concentration level of the debris, or a type of the debris. An apparatus for use in debriding a root canal of a tooth includes a microcannula or a macrocannula configured to evacuate a fluid in the root canal, and a sensing mechanism fluidically coupled to the microcannula or the macrocannula, the sensing mechanism configured to continuously sense debris in the evacuated fluid in real time.

Digital orthodontic setup using a prescribed ideal arch form
The invention generally relates to methods, systems, and computer program products for digital orthodontic setup using a prescribed ideal arch form. The invention may include an imaging system, an orthodontic device production system, and an orthodontic treatment system interconnected by way of a network. The orthodontic treatment system may facilitate manipulating one or more reference teeth into a position by the dental practitioner. The orthodontic treatment system may further facilitate selection of an ideal unit-less arch form and scaling of the ideal unit-less arch form into a scaled ideal arch form to fit the reference teeth. After the selected ideal unit-less arch form is scaled to fit the reference teeth, the remaining teeth are positioned with respect to the scaled ideal arch form, either manually by a dental practitioner or automatically by an alignment algorithm.
