Abstract:
PROBLEM TO BE SOLVED: To provide an improved method and system for repositioning teeth from an initial tooth arrangement to a final tooth arrangement. SOLUTION: The system for repositioning teeth comprises a plurality of individual appliances 100. The appliances 100 are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The system of appliances 100 is usually configured at the outset of treatment so that the patient may progress through treatment without the need to have a treating professional perform each successive step of treatment.

Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method for identifying a mass-customized part by encoding a part identification into a multi-dimensional bar code and using a stereolithography apparatus (SLA) to make the part with a multi-dimensional bar code embedded therein. SOLUTION: An identification system includes a means for encoding the part identification into the multi-dimensional bar code, a means for synthesizing the bar code and three-dimensional (3D) part data into a synthesized 3D configuration, and the stereolithography apparatus (SLA) for receiving the synthesized 3D configuration and making the part according to the embedded multi-dimensional bar code. The multi-dimensional bar code is preferably a three-dimensional bar code. The multi-dimensional bar code preferably includes a plurality of layers. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide appropriate embedded functions and methods of a dental appliance. SOLUTION: Traditional orthodontic treatment involves the use of basic repositioning devices, and the use of supplementary devices, components or accessories to achieve desired end results. The components may be mounted on fixed and non-removable devices, or may be part of a removable appliance typically worn prior to the application of the fixed device. As with traditional treatment is used, it may be desired to use the similar components when teeth are repositioned with removable elastic repositioning appliances. Due to the nature of elastic appliances, the components may take a variety of forms ranging from readily available traditional accessories to specially created devices. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a system and a method suitable for dental treatment planning. SOLUTION: Computer-implemented systems and methods implement a dental treatment plan by specifying tooth movement patterns using a two-dimensional array; and generating treatment paths to move the teeth in accordance with the specified pattern. Further this invention provides a computer system including a processor, a data storing device coupled to the processor, a computer executable code for specifying the tooth movement patterns using the two-dimensional array, and a computer executable code for generating treatment paths to move the teeth in accordance with the specified pattern.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved dental appliance system (100) and a method for using and fabricating the improved appliance (100). SOLUTION: This appliance (100) includes a polymer overlay or shell (102) having a tooth-receiving cavity 120 formed therein. This dental appliance (100) has the necessary stiffness or strength to firmly secure the appliance (100) onto a tooth and provide controlled force required for repositioning the tooth, until such time as removal of the appliance (100) is desired. This appliance (100) may be configured for use with a removal mechanism which provides for selective release of the appliance (100) from the tooth as the removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved device, system and method for orthodontic treatment using elastic repositioning appliances capable of concurrent executing and/or improving dental and periodontal therapies. SOLUTION: The system is for tooth repositioning and replenishing an agent 15 into the oral environment. The system comprises: at least three tooth repositioning devices 20 which include polymeric shells 12 with cavities, the shells can be removably set on teeth, wherein the cavities of the continuous shells are formed so as to be capable of repositioning a tooth from an arrangement to the next; and a means which replenishes the agent into the oral environment when the device is positioned at a predetermined position by a tooth and is connected to at least a part of the device.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved system and a method for removably attaching a dental positioning appliance. SOLUTION: The improved system and the method are for removably attaching the dental positioning appliance 105 to the dental features of a patient during orthodontic treatment. The appliance 105 is preferable over conventional braces for its comfort, appearance, and easiness. The appliance 105 functions by applying force to specific surfaces of teeth or the dental feathers 103 as a cause for direct movement. However, the level of the force applied, or the type of movement, is usually dependent on the surface characteristics and the position of the dental features 103. This aspect is inadequate to provide a sufficient anchoring or to impart a considerable force on the teeth 103 to be repositioned. Such limitations may be reduced by use of one or more attachment devices which may be positioned to the teeth or the dental features 103 to provide appropriate physical features.

Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method to remove a gingiva from a tooth. SOLUTION: The method executed with a computer to detach the gingiva from the tooth comprises a process to determine a severing surface along the gingiva, and a process to provide the tooth with the severing surface to detach the gingiva from the tooth with single severance. In one embodiment, the severing surface curves. In another embodiment, the severing surface is expressed with a function. In another embodiment, the severing surface is expressed with a spline function and a quadratic function. In another embodiment, the severing surface is expressed with a spline function and a parabolic function. Moreover, in another embodiment, the severing surface is adjusted reciprocally.
